Green Materrs: Urban Legends and Illusions

Published with the permission of the American Women's Club of Zurich

When Switzerland introduced the trash bag tax in the early 90s, an urban legend calling on householders to put paper in their trash bags achieved amazing popularity. Rumor had it that incineration plants need paper in their trash mix in order to heat up to the required temperature. Ultimately, the operator of a major incineration plant was given full-page newspaper space to explain why “it just ain’t so.” Now another urban legend is making the rounds.

Let me set things straight: whatever you may have heard, incineration plants do not need to burn glass to achieve efficient burning temperatures. The explanation for this is the same as for the earlier rumor—incineration plants don’t need to burn any of the materials we can sort and recycle. We don’t need to worry about the burning temperature either. Plastic waste has replaced paper as a heat source for the furnaces. In fact, plastic waste is such a large percentage of household garbage that, instead of being an aid to efficient burning, these large amounts of plastic produce extremely high furnace temperatures and increase incinerator wear-and-tear. Recycling paper and glass is certainly cheaper than paying trash bag tax unnecessarily, and recycling helps the environment by reducing pollution and lowering our energy and resource consumption. Please put empty glass jars and bottles--you may leave the paper labels on them--in your town’s recycling bins.

Battery recycling is another subject that often needs clarifying. Contrary to a current misconception, battery recycling consumes energy rather than saving it. This is because batteries, whether they are being manufactured, used, or recycled, consume more energy than they give out. They are convenience items and should only be used when it is impossible to draw current directly from the electric outlet for your purposes. Recycling batteries is important because the recycling process enables reuse of important materials such as iron, nickel, manganese, and zinc and also keeps toxic heavy metals such as lead and cadmium out of the environment. Recycling also means less mining and transport of these materials and thus lowers batteries’ environmental impact. Avoid buying Nickel-Cadmium batteries whenever possible. These contain large amounts of toxins, as do many button batteries, which often contain mercury. “Buttons” are particularly dangerous because they can be easily swallowed by small children. Recycling batteries is simple. Every store that sells batteries, including grocery stores, is required to provide recycling containers for customer convenience.

“Yes, Virginia,”….recycling plants really do recycle. The suggestion that they don’t is an urban legend in its own right. The lesson I learned from researching these urban legends is that we can trust the Swiss recycling system. It has been tested and proven practical, environmentally desirable, and economically sound. The technology is reliable and up-to-date, and towns do their best to make recycling as straightforward and convenient as possible. I spent quite a few mornings last year attending citizens’ advisory committee meetings in our town. Our committee was asked to help with the revision of local disposal and recycling infrastructure and procedures. Newcomers may find these procedures complicated at first, but I confidently affirm that every effort was made to simplify them as much as possible.

Illusions of another ilk have to do with us humans. How many times have you heard someone say that an environmentally helpful activity, such as using public transport or recycling, is “only a drop in the bucket?” To say that is to suggest that our contribution (in this case to the environment) doesn’t matter and implies that we are powerless. Whenever we begin to think about global problems, most of us feel pretty small. We aren’t.

A psychologist friend of mine counsels many people who suffer from personal difficulties. When I asked her how their pain affected her, she said something I will never forget: “Yes, it’s hard, but I don’t give up or feel discouraged because I can always do something to help.” Each of us can always do something to help even if what we do seems small to us. As a matter of fact, students of history often tell us that big changes happened because so-called “ordinary” courageous people worked for and supported them. Margaret Mead’s profound insight still rings true: “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.” Women are good at seeing what needs to be changed. We care for (and about) future generations and the world they will inherit. All of us can play a part in building a better world.

Technology and Sustainable Resources

Floating Windmills with Umbilical Cords

Norway is putting windmills on floats and setting them out to sea. Norway’s experience with offshore drilling ensures that the windmills won’t go too far; the windmills have long shifting anchors, similar to those used with oil rigs. To transport the collected energy back to shore for storage and onward transportation, engineers have added a reverse umbilical cord of sorts, a cable which carries the nourishing energy back to the motherland.

The Global Concerns group spent an intense afternoon crawling through the nooks and crannies of energy-related technologies. Our speaker was Gina Domanig, Managing Director of Emerald Technologies; Gina is a venture capitalist in the area known as ‘Cleantech’, a term used to describe energy technologies and services which focus on improvements in process efficiency, pollution reduction, or the use of renewable resources such as sun, wind, and waves.

In the world of venture capitalists, the emphasis today, we learned, is on sun, wind and waves. For those who missed the lecture, bio-fuels are out. The challenges and the opportunities are many, but they always come back to collection, transportation, and storage. Collecting solar energy in a dessert seems like a good idea. But the collected energy must be transported to the consumer, i.e. fed into an electricity grid, which can then move and store electricity until the consumer needs it. Many of the world’s deserts are simply too far away from the consumer markets and their grids.
Not so with Portugal; this country enjoys sunny skies and is a part of Europe’s dense integrated electricity grid. And Portugal has a green energy vision. By the end of 2011, Portugal will be equipped with a network of electric-car recharging stations and a fleet of battery-powered vehicles to make use of them. To meet the energy demand, Portugal is in the process of building what will be the largest solar photovoltaic plant on the planet. Looking at the details, we learn about a novel way to counter-balance the consumption peaks that might be caused when too many cars ‘tank up’ at the same time: the cars will not only store energy, they will also sell back energy to Portugal’s power-grid.
After and during a well thought-out talk, Gina fielded many questions, a few of which are repeated here:
  • Could Portugal become a net energy exporter? What impact might that have on nuclear power sellers in other countries?
  • Will robots resolve the problems of cleaning solar collectors and repairing offshore windmills?
  • Switzerland has little sun, no sea, and its wind will not be easy to capture. Which are the technologies that Switzerland might pursue to take advantage of the rising green tide? Hint: membrane technologies, geo-thermal processes, bio-tech areas such as fermentation.

DISINFORMATION

What Is Disinformation?

According to Wikipedia, 'Disinformation is false or inaccurate information that is spread deliberately. It may include the distribution of forged documents, manuscripts, and photographs, or propagation of malicious rumors and fabricated intelligence. Disinformation should not be confused with misinformation, information that is unintentionally false.' http://en.wikipedia.org/wiki/Disinformation


Disinformation is part of our life – in what we read, hear, or see. It can make people feel insecure and doubtful, make people believe that a matter is clear when it is not. Areas where disinformation is commonplace:

  • Economics and finance
  • Media
  • Science
  • Education
  • Governments
  • Environmentalists
  • Medicine
  • Real Estate
  • Politics
  • Companies
  • Marketing

In summary - everywhere!!!!

How can we find out if our information is genuine, i.e. not a deliberate clouding of the facts? How can we know if and when an information is presenting only one side of a multifaceted issue? Some simple measures include:

  • Talking to people of varied educational backgrounds, cultures and countries.
  • Reading on the topic in as many different magazines out of as many different countries, with varied political interests, and in as many languages as possible.
  • In the area of science, look for peer reviews and comments
  • Rely on people one trusts out of personal experience.
  • Use the web, but discriminately. Not everything on the web is true.
  • While reading, look for certain phrasings in the text that may carry a hint that what sounds clear-cut and firm is actually anything but.

The following article, Detecting disinformation without radar, by Gregory Sinaisky and published in the Asia Times, is a helpful starting point.
