Green Shopping Basics - What You Should Know Before You Shop Green


Green Shopping Basics - What You Should Know Before You Shop Green

Going green always starts with good intentions, but the massive amount of green terms can sometimes be overwhelming. Here’s some of the common green terms you’ll hear and what they mean.

Organic
The term organic can often be used very broadly, but typically refers to products that have only organic components, produced without pesticides, herbicides, insecticides, or fertilizers or other harmful chemicals.
Look for: USDA Certified Organic

Sustainable
Products or materials that are described as being sustainable contain materials that do not deplete the Earth of its resources and is easily replenished. There are many common types of materials that are considered sustainable:

Bamboo - Bamboo is a fast-growing and renewable resource that can be used to make fabrics, flooring, furniture and other products.

Jute - Jute is a long and shiny vegetable plant fiber that can be woven into a strong thread or twine. It is commonly used to create cloth or used within carpets, and rugs.

Hemp - Hemp is a fast-growing plant that is most commonly used for its strong fibers to create cloth used in bags and clothing. It can grow organically and also be used to create oils for cosmetic products as well as be used in food.

Sustainable Wool - There are many types of sustainable animal wools such as alpaca fibers or merino wool that can be used to create strong fibers commonly used in clothing.

Energy-Efficient
Products that are energy-efficient are design to consume less energy when operating without sacrificing performance, reducing long-term environmental and cost impacts. Energy-efficient products can range from appliances to light bulbs as well as contain different levels of efficiency.
Look for: Energy Star Qualified, EPEAT Rated

Post-Consumer Recycled
Once a product has completely served its purpose, what remains are post-consumer materials that would otherwise be disposed as waste but are instead recycled. This would include products such as old packaging, glass bottles, aluminum cans, and plastics. When you recycle from your home these products become post-consumer recycled.

How is this different vs recycled? Regular recycled materials can contain a combination of materials, often coming a scraps or other by-products as a result of manufacturing. This could include both pre-consumer and post-consumer waste.

Recyclable
A recyclable product means that it can be recycled and be used to create future products. Polypropylene #5 is a common plastic to look for in products which is one of the most easily recyclable plastics.
Look for: Polypropylene #5

Reusable
Reusable products mean that a product can be used multiple times before the product is discarded or recycled. Some common reusable products are shopping bags, water bottles and tableware.

Fair Trade
Fair Trade is a social movement that promotes certain standards of sustainability practices and empowering producers in developing nations. Fair trade supports fair prices, fair labor conditions, community development and environmental sustainability.

Volatile Organic Compounds (VOCs)
VOCs are organic chemical compounds that have high vapor pressure and easily evaporate at room temperature. VOCs can be released from many household items such as paints, flooring, upholstery, and cleaners. These VOCs are not only air pollutants but have also been known to cause health effects as well.
Look for: Low-VOC, Zero-VOC

Bisphenol A (BPA)
BPA is an organic compound that is used in the creation of many plastics and resins. Most commonly you will find BPA used polycarbonate bottles. While there is some controversy about the effects of BPA, some research has raised serious health concerns about the usage of BPA.
Look for: BPA-free

Biodegradable
Biodegradable means that a substance can be naturally decomposed by biological processes. If a product is biodegradable, this means that it can be disposed of with no negative environmental impacts.

Solar-Powered
Solar powered products are powered using energy from the sun. Solar power can be used in a range of products from small household gadgets to entire home heating systems.

Cleanliness Analysis


Cleanliness Analysis

You cannot control that which you do not measure.

In more and more industries, the exact knowledge of particle contamination is gaining in importance. Contamination of materials in dimensions of a few micrometers was mainly of concern for the pharmaceutical and semiconductor industries. However, not only manufacturers of circuit board components, but also traditional car parts suppliers face new demands on particle recognition and contamination source identification.

Cleanliness for the automotive parts manufacturers has become a huge topic in today’s ever challenging continuous improvement world. The need to define, measure and control the levels of particulate contamination on product is the new norm for suppliers and automotive OEM’s.

Cleanliness directly relates to product warranties, reliability, performance and safety issues. It has long been known that a dirty product gives us poor quality and low life expectancy. The dirtier the transmission from new, the less time it will last.

It is crucial now to identify particles and their source so that effective elimination can be achieved. Residual contamination consists of particles that persist on the component’s surface after the final step in manufacturing. Such contaminants are introduced via parts from suppliers or arise during processing. After vehicle assembly, the contaminant particles can cause severe damage, loss of function or reduce the lifetime of the product.

Cleanliness is defined as the contamination level of a component surface. Common measures to quantify the cleanliness are mass of the contaminants as well as number, size of the dirt particles. In general, the customer will specify contamination limits. The supplier then has to maintain these levels and document them regularly by means of contamination analysis.

The analysis of the contamination has to be proven to not affect the result and to be effective in evaluating all the contamination present. Methods of extraction and evaluation are specified in the international standard ISO 16232. Particular attention must be paid to the extraction method to ensure no contributing factors are introduced to the evaluation. There are different methods of counting the resulting extracted particles but by far the most accurate, repeatable and cost effective is automated microscope analysis. The microscope with software can scan the filter membrane; sort the particles by size class and even determine basic material composition (metal, non-metal, fiber). Once the data is gathered a custom report can be generated based on the customer requirements.

Why You Should Start Recycling Today


Why You Should Start Recycling Today

Recycling is like exercising - everyone knows we should do it, but not all of us do it as frequently as we should and many of us don’t do it at all. However, there are tons of reasons why you must make an effort to recycle as much as feasible. If you have not been diligent about recycling, this article provides some great reasons why you should start.

1. Recycling cuts back on global warming.
2. Production of certain materials from the start can release serious amounts of CO2 into the atmosphere.
3. Recycling paper saves trees - for each ton of paper recycled, 17 trees are saved. Each of these trees can extract around 250 pounds of carbon-dioxide from the air in a year.
4. Recycling makes us more energy-efficient. It frequently takes a great amount more energy to form something from nothing than to reuse it.
5. It keeps our landfills from overflowing. We are fast running out of space for landfills especially near towns.

Beach towns have been dumping trash into their seas for years to by-pass the difficulty, but with widespread sea ecological collapse, this isn’t longer a practicable option. Worse yet, it’s hard to find land in suburban and agricultural areas whose residents will permit landfills to come into their areas without a fight. The squeeze for rubbish heap land is only going to become worse in the future.

Recycling gives us some hope. Studies show that 60% to 75% of rubbish in landfills can be recycled. That suggests that if everyone recycled, we would have 60% to 75% less rubbish in our landfills, and we’d need at least that far less land for rubbish disposal. The rubbish in landfills is mostly not treated in any way it’s simply thrown in a huge hole and buried over. A lot of this rubbish isn’t environmentally friendly or readily biodegradable and it is unsurprising that contaminants can get into our water. It is also a major reason why it isn’t safe to drink from streams and brooks when you are hiking and camping even when it’s like you are in a spotless environment. It reduces air pollution. A lot of factories that produce plastics, metals, and paper products release poisons into the air.

For instance, plastics are usually burned in incinerators. Plastics are made with oil, and that oil is released into the atmosphere when the plastic burns, creating significant greenhouse-gas emissions. From manufacturing to processing, from collection to invention it’s common knowledge that recycling is an expansion industry, earning billions of bucks yearly. Our desire to recycle is only going to grow more insistent as populations grow and as technology changes. It adds to property worth. It is obvious a rubbish heap near your house can decrease your property values significantly. Recycling decreases the quantity of land required for landfills. This decreases the quantity of homes near landfills, keeping property values up and house owners cheerful. The more folks recycle, the less landfills we need and if enough folks pitch in, recycling should pay off for everyone. It is good business. Pitting business against the environment is a lose-lose situation - everyone suffers.

Commercial factories and processing plants save masses of cash on energy and extraction systems when they use recycled materials rather than virgin resources. They also make sure that basic resources don’t become a scanty commodity, keeping demand and costs down and making sure that their business can continue for years to come. One person can contribute. Many of us think this is true with recycling, too but the reality is that small acts of recycling make a giant difference.

Clean Green Computing

Green and Clean Computing

Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.

The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.

There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.

The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.

The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.

Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.

Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

Water Efficiency - Water Used in Generating US Electricity

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

  • Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
  • Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
  • Geothermal power plants add another 2 billion or so gallons a day.
  • Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day - or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

  • The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
  • At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
  • The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

  • Stretches below dams are often completely de-watered.
  • Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
  • A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
  • By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
  • The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
  • This often eliminates native populations of fish and other wildlife.
  • Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
  • As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.

Gasification Sees a New Dawn


Gasification Sees a New Dawn

If you search for gasification and terms like “wood stove” on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.

So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?

What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.

This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.

Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.

Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.

These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.

Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.

Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.

Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.

Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.

Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Recycle, Reuse and Reduce


Recycle, Reuse and Reduce

Does you family recycle aluminum cans? Do they do it to get a little extra cash or because it is the responsible thing to do? How much do they, and you, know about what happens to the can after the soda is gone? Here is a quick true and false quiz on recycling. It will only take 2 or 3 minutes to find out what you know and what you need to know about the importance of families recycling.

Circle the answer for each of the 6 questions. Now test the other members of the family.

1. In the time it takes you to read this question, 50,000 12-ounce aluminum cans are made.

                  True or False

2. When you recycle one aluminum can you save enough energy to equal a half gallon of gasoline?

                  True or False

3. There is no limit to the amount of times aluminum can be recycled.

                  True or False

4. We use over 80,000,000,000 (billion!) cans a year.

                  True or False

5. At one time, aluminum was more valuable than gold.

                  True or False

6. More aluminum goes into beverage cans than any other product.

                  True or False

Surprise! All of the answers are true.

Did you know that for every $10 spent buying things $1 or 10% goes for packaging that is thrown away. Packaging, and that includes aluminum cans, represents 65% of household trash. Wow. What a waste of money and resources. We can do better than that.

Our family is making a special effort to Recycle, Reuse and Reduce. Will you join us in helping to protecting our earth and natural resources? Maybe your family could put up a special box to save aluminum cans for the recycling center.

USA - China - A G2 For Climate and Economy?


USA - China - A G2 For Climate and Economy?

China appears to view global warming as an economic issue, Obama’s administration is primarily focused on the current economic crisis as well, but climate change is also a serious crisis and a threat to the world’s economic system itself with all its present and predicted impacts. Don’t these global problems require an integrated economic and environmental strategy? The hypothesized summit between Barack Obama and the Chinese president, Hu Jintao, could be an important step to accelerate urgent actions needed both to face the global economic downturn and to build a solid climate pact.

China, in its last 5-year plan, sets targets to reduce national energy intensity (energy used per unit of GDP) by 20% between 2006 and the end of 2010. According to Deborah Seligsohn, China Program Director on Climate, Energy and Pollution of the World Resources Institute, this target seems to be realizable given their latest remarkable record (-1.8% in 2006, -3.7% in 2007, and -4.2% in 2008.) Last month Hillary Clinton met experts from the Asia Society and the Pew Centre for Climate Change that together wrote a report that could help the creation of this US-Chinese partnership on climate change. But the good examples from China, although not directly referred to CO2 emissions, and Obama’s ambitious plan on energy and climate will need decisions from other 13 countries (or federations such as the EU), including Russia, India, Japan to get 80% of world’s emissions “under control”. Nowadays the other 173 countries account for about 20% of total CO2 emissions, but population increase and old development patterns could dangerously increase their “pollution share” in the future: every nation will be then required to cut the CO2, but large amount of money are needed to do so. Where will our leaders take Dollars, Yuan or Euros these days?

Next steps: -264 days to COP15:
Two events along the path to Copenhagen will take place in Bonn from March 29th to April 8th: the 7th session of the AWG-KP (Ad Hoc Working Group on Further Commitments for Annex 1Parties under the Kyoto Protocol) and 5th session of the AWG-LCA (Ad Hoc Working Group on Long-term Cooperative Action under the Convention). As we can read on the UNFCCC website “this is the first of three planned negotiating sessions before COP 15 in December” and can hopefully prepare a good ground for delegations and political leaders to decide upon.

Mobile Car Wash Rules Slated City of Oxnard CA


Mobile Car Wash Rules Slated City of Oxnard CA

The City of Oxnard, California is concerned with the quality of its storm water and rightfully so, as it has made great strides over the years. Oxnard CA is also home to the gateway to the channel islands with some incredible beaches and nice resort style living, and all that storm water leads to the ocean and those beautiful beaches. Thus, the city has chosen to start cracking down on mobile car washes.

This should not come as any surprise to anyone, as the city had previously implemented many programs to help clean the storm water runoff. They had developed a nearly bullet proof NPDES plan to insure clean water. The beaches never looked so good and this recent ruling to finish that job nearly a decade and a half later has come all the way down to washing of cars.

Our company had dealt with this issue in the late 80s and early 90s and helped write all the NPDES BMPs for several counties near there. The devices used are fairly easy to buy, and it really doesn’t take much, further it is my contention that all mobile car washes ought to follow the rules to protect the environment and there ought to be no excuses on that.

Indeed, over the years, we’ve worked with many cities on this, in fact, one thing we did was join the committees to help write the original BMPs for surface cleaners in Ventura County, CA where the City of Oxnard is located. A mobile car wash operator should not only follow the rules but be part of the solution. Think on that.
