SUMMARY REPORT

Period Covered : 25 Nov 2002 to 1 Dec 2002

Item 1

San Francisco moves ahead on green energy goals

Summary

The city of San Francisco awarded the first contract in its efforts to produce solar power from panels atop municipal buildings. Voters approved two propositions in November 2001 to permit bond issuance to raise funds for renewable energy generation projects.

San Francisco Public Utilities Commission (SFPUC) is spearheading the renewable energy efforts by placing solar panels on San Francisco's public buildings. Its first project from the two propositions is the solar power development efforts on the Moscone Center, a prominent convention center.

Solar power generation and energy efficiency are the two parts of the Moscone project. Solar power installation on the Moscone Center's roof will produce 825,000 kilowatt-hours each year. Energy efficiency improvements to the Center should save about 4.5 million kilowatt-hours of electricity a year. These two efforts are projected to save the city enough electricity to power 1,000 homes.

Item 2

More aid to phase out ozone-depleting substances

Summary

More than 100 governments meeting in Rome are expected to negotiate more than US$500,000 in aid to developing countries to help them to reduce the use of the chlorofluorocarbons (CFCs) and other ozone-depleting substances, an action called for in the Montreal Protocol.

The phase out of CFCs by developing countries is the top priority today for the Montreal Protocol on substances that deplete the ozone layer. Scientists believe that only when all countries meet their Montreal Protocol targets, the stratospheric ozone layer will stabilize and then return to full health within 50 years.

Developing nations are slated to reduce their use and manufacture of CFCs by 50% in 2005 and 85% in 2007 under the Protocol. Developed countries have almost completely switched away from using CFCs in 1996.

The Protocol's Multilateral Fund will be replenished for 2003-2005, but negotiators must decide on the amount. The fund is used by developing countries to close down CFC production facilities, increase production of ozone-friendly chemicals, and switch to more ozone-friendly products such as CFC-free refrigerators and air conditioners

Item 3

Japan to stiffen curbs on dioxin emission from incinerators

Summary

Japan will stiffen regulations on the highly toxic dioxin in gas discharged from incinerators and empower prefectural governors to order commercial operators of incinerators to observe the new standards, from 1 Dec 2002.

The new directives stipulate that the level of dioxin from large incinerators with the daily capacity to burn 200 kilograms or more in garbage and industrial waste must not exceed 1 nanogram per cubic meter of an incinerator's exhaust gas.

Item 4

Biological reactor that converts food waste into biodegradable plastic

Summary

Scientists in Hawaii have developed a biological reactor that converts a slurry of food waste into a biodegradable plastic.

According to the scientists, food waste is mixed with water to create a slurry and stored in a warm, airtight container. Bacteria would then break down the organic molecules in the food waste, releasing acids as by-products. The acidic products are then siphoned off and fed into a sack-like sheath dangling inside a second vessel. The bacteria in the second vessel would then convert the acids into biodegradable polymer. The bioplastic polymer makes up around 70 per cent of the bacterial mass harvested from the process. About 22 to 25 kilograms of polymer can be produced for every 100 kilograms of slurry.

The polymer created could be used to make greener packaging, disposable products such as bottles, or even pills that dissolve slowly to release drugs in the body.

Item 5

Coal-based gasoline process to be available in 5 - 10 years

Summary

The U.S. Department of Energy (DOE) announced that it has awarded $5.6 million to a consortium of universities studying ways to make clean transportation fuels from coal. The award will advance ongoing research on C1 chemistry. C1 chemistry refers to technology that uses synthesis gas produced from coal or natural gas as feedstocks for producing ultra-clean liquid transportation fuels and hydrogen.

According to professor Gerald Huffman from University of Kentucky, recent research advances indicate that C1 chemistry will soon be able to produce such fuels from coal and natural gas at a price that is competitive with the cost of transportation fuel produced from oil. Additionally, the use of these ultra-clean fuels produced by C1 chemistry will also have a very beneficial effect on the environment.

Item 6

Electronics firm develops revolutionary plastic recycling technology

Summary

Japanese electronics firm Matsushita announced that it has developed a method of recycling the plastic casings for electronic equipment.

The plastic is crushed and then heated to 160 - 200oC until it becomes soft. This is a relatively low temperature, which means that the physical characteristics of the plastic are not damaged, says Matsushita. A solvent is then added that melts only the flame retardants, which are then separated from the plastic using the company's newly developed kneading technology. The plastics can then be molded into the shape required for the new product.

Matsushita plans to release a commercial version of the technology during the 2003/4 financial year.

Item 7

New sliver cell offers revolution in solar power

Summary

A joint venture between the Australian National University and Origin Energy has developed a new type of solar cell with the potential to revolutionise the global solar power industry.

A solar panel using Sliver Cell ™, uses just one tenth of the costly silicon in conventional solar panels while matching power, performance and efficiency.

The new technology reduces costs in two main ways - by using much less silicon for similar efficiency and power output, and needing less capital to build a solar panel plant of similar capacity.

Item 8

Mercury in fish linked to heart attacks

Summary

In a collaboratively study of eight European countries, scientists have found that eating fish from mercury contaminated waters may counteract the health benefits of omega3 fatty acids, also present in fish.

By measuring mercury in toenail clippings of heart attack patients and healthy volunteers across Europe, scientists correlated mercury intake with docosahexaenoic acid (DHA) body levels. DHA in body fat is a marker of fatty fish intake. Mercury and DHA levels were found to be related, indicating that fish is likely to be the main source of toenail mercury in the populations studied, with mercury levels 15% higher in coronary patients than in the healthy volunteers.

However scientists add that a fish diet is still healthy, provided the fish has safe levels of mercury.

Item 9

EPA proposes final air toxics standards

Summary

The US EPA has proposed the final 10 air toxics standards as required under the Clean Air Act. Air toxics, also known as hazardous air pollutants are known to cause cancer and other serious health problems in humans. In 1990, Congress required EPA to control emissions of 188 air toxics from more than 100 different types of industries.

The standards being proposed are:

  • auto and light duty truck surface coating;
  • combustion turbines;
  • industrial, commercial and institutional boilers and process heaters;
  • iron and steel foundries;
  • lime manufacturing;
  • metal can surface coating;
  • plywood and composite wood products manufacturing;
  • primary magnesium refining;
  • reciprocating internal combustion engines; and
  • taconite iron ore processing.

Item 10

Phytoplankton implicated in global warming

Summary

Researchers at the Scripps Institute of Oceanograpy in San Diego, California, used modeling and satellite imagery to show that solar radiation that would otherwise be reflected back into space was being absorbed by phytoplankton, contributing to global warming.

The Scripps study found that the radiation absorbed by phytoplankton raises global average temperatures by 0.1 to 0.6 degrees Fahrenheit (0.06 to 0.33 degrees Celsius) compared with computer models without phytoplankton.

Phytoplankton are microscopic plant-like organisms that free-float on the world's oceans, and are the major source of sustenance for animal life in the seas. They had not previously been associated with climate change.

The scientists argue that the 'phytoplankton effect' needs to be considered in future predictions of climate change.
