Laws and Regulations
40% waste reduction goal after 2000. State expects to meet the 40% goal. 1998 recycling rate was 36%. State Solid Waste Management Plan sets a diversion goal of 50% by 2005. There is no mandate for recycling or diversion, and no penalties.
~ Reports have city officials in Burlington, Vermont set to enforce a law that prohibits idling of internal combustion engines between April 1st and November 1st, 2007. Burlington Mayor Bob Kiss said that idling has a cumulative effect on greenhouse gas emissions, and that not idling could reduce emissions in a meaningful way. The fine for non-compliance will be 45 bucks. The twist is that the anti-idling law is already on the books, and has been since 1990. Why the powers that be in Burlington have suddenly decided to hold a press conference on enforce this 17-year old law is reportedly due to increasing public demand to do something about global warming, and has nothing to do with political aggrandizement of any kind. Refrigerated trucks full of Ben & Jerry's or ice-cold Labatts '50s are exempt from anti-idling restrictions. http://jalopnik.com/cars/news/no-idling-for-you-251141.php

    Volkswagen unveiled the cleanest ever TDI engine. First test drives demonstrate the high potential of Volkswagen technology, which consequently reduce nitrogen oxide. In the VW Jetta a new 2.0 litre Common Rail diesel engine with a nitrogen oxide reservoir catalytic converter was used, which complies to the Californian emission standard “Tier 2 / Bin 5”. These requirements are considered the most stringent worldwide. The first production run of the “Clean TDI” with nitrogen oxide post-treatment system will be made during 2008 in the USA.
    The central theme of the entire concept is the reduction of nitrogen oxide. The engineers in Wolfsburg reached this goal through internal development of the motor and the use of new emission post-treatment technology. The result: up to 90% less nitrogen oxide emissions (NOx).
    This drastic reduction was necessary in order to comply with the “Tier 2 / Bin 5” norm, which applies to California and four other states in the north-east of America (Massachusetts, New York, Vermont and Maine). This norm limits nitrogen oxide emissions to 70 mg per mile. In order to comply with this standard, completely new emission ­ treatment technology was necessary. Volkswagen has thus developed two systems connected to the oxidation catalytic converter and the particle filter in the exhaust system.
    New NOx reservoir catalytic converter technology is currently being tested for car models below the Passat class. Nitrogen oxide is absorbed like a sponge, leading to a high level of efficiency. As with the particle filter, the system is regularly cleaned without the driver noticing. To do this, the engine management system changes operation modes for a few seconds.
    Larger and heavier models feature the Selective Catalytic Reduction (SCR) catalytic converter. The central element is an aqueous solution such as AdBlue, which is transported in an additional tank made from stainless steel or plastic. 32.5% of this solution is comprised of urea, and is continuously injected into the exhaust system in front of the SCR catalytic converter using a metering valve. The dosage is made according to the gas emission stream.
    The urea solution is finely atomised by a grille and is converted in hot exhaust gas into ammonia before it reaches the catalytic converter. The ammonia then reacts with the nitrogen oxide in the catalytic converter and separates it into nitrogen and water. Unlike pure ammonia, AdBlue solution is non-toxic, odourless and biodegradable. Volkswagen intends to install the additional tank so that the car can be driven without main­tenance between two garage inspections - the garage simply refills the tank at the next scheduled inspection date. According to American regulations, the complete system must be fully functional for at least 150,000 ­miles. http://www.worldcarfans.com/rsslink.cfm/article/2070104.006/ volkswagen/volkswagen-unveils-cleanest-tdi-engine-ever
