China has a severe shortage of skilled talent and, in a policy reversal, has decided to open its doors to talent from around the world. This could mean that the brilliant NASA scientists the U.S. laid off, could find new employment — and a new home — in Shanghai or Beijing.
Chinese research labs have long had difficulty recruiting qualified workers to perform necessary research and development, and its corporations struggle to find competent managers. The situation will likely get worse as China’s high-tech industries grow and it increases its national R&D spending from the present 1.62 percent of GDP, according to the Chinese government, to the planned 2.5 percent by 2020. China’s President Hu Jintao, in May 2010, declared talent development a national priority in order to fill the void. The goal is to dramatically increase the education level of China’s workforce and to build an innovation economy.

LED’s Poised to Take Over CFL’s
According to experts in the LED industry, the LED lighting market is strong and constantly changing as the technology evolves. Only one year ago some bulbs would have cost almost double what they are priced today. Since LED technology is advancing so rapidly, newer LED bulbs are coming out brighter and cheaper than they were before. LED lighting has continued to gain market share in 2011 as governments around the world have adopted policies in favor of LED lighting because of growing environmental concerns. LED light bulbs for the home are one of the easiest ways to save up to 90% on your home lighting bills if you are switching from incandescent bulbs.

The most popular way to extend the range of an electric vehicle is to add a small gasoline engine coupled with a generator as done in the Chevrolet Volt plug-in hybrid. The most popular way to extend the range of an electric bus is to add a fuel cell that generates added electrons. During the Winter Olympics, 100,000 riders were transported up Whistler’s 12 percent grades on 20 hydrogen fuel cell electric buses. Now SUVs made by Hyundai-Kai, General Motors and Toyota are also testing Fuel Cell Electric Vehicles (FCEV). More…
The ultimate model which addresses all possible aspects of environmental sustainability in rubber recycling is still Devulcanization but should start right from the collection of tires. This means the starting point should be at the tire collection centers or in the US possibly at the landfills. Here we are not talking about solid waste management anymore but effectively managing a vital raw material in process.
Addressed properly the tires would not be dumped in the open but would be separated out between passenger car and commercial vehicle (truck) tires, making it possible to split up the feedstock into types ie. Mostly Natural Rubber (80/20) from Commercial vehicle tires and Mostly Synthetic (60/40) for passenger car tires. This important step also makes it possible to shoe horn in a step which could see the eventual removal of the Butyl inner liners by grinding or peeling off. The resultant by-products would be butyl scrap feedstock and butyl free scrap tire feedstock, an interesting and very significant change to the current situation.
MOVE WITH PURPOSE, COMMITMENT
We live in a world that has taken its bounty and blessings entirely for granted for a very long time. The most basic levels of reciprocation to maintain balance in our environment were ignored and we might have pillaged our way to a point of no return. The only option left beyond packing up and leaving mother earth is to do away with polluting processes and address sustainability in any and all our activities.
The challenge before us is to make sustainable activity in the form of greentech and applications related to the improvements in efficiency and energy conservancy, cost effective and profitable. Fortunately, we do have solutions that can go a long way towards mitigation. Some challenges require us to invent, others called for applying common sense and using existing Smart solutions.

TYRES. They are on our cars, buses, trucks and motorcycles. Yet, how many of us actually know what happens to them once they outlive their usefulness?
The issue of scrap tyre recycling is often placed down the pecking order after the primary worries of illegal logging, open burning and other forms of pollution. Granted, they may form only a small part of our lives but stacking these unwanted rings of rubber up into a pile will give a sense of what many nations are struggling to deal with – or get rid of.
Two industry organizations are objecting to a proposal by the Environmental Protection Agency (EPA) that would designate scrap tires as a “solid waste.” If the regulations are adopted, manufacturers that currently utilize tire-derived fuel (TDF) — such as cement kilns and paper mills — will have to operate under the tougher standards directed at commercial incinerators.
TDF-burning facilities would fall under more stringent Section 129 emissions regulations in the Clean Air Act, which would mean revamping or replacing current combustion units. The fear is that these firms would reject using TDF in favor of more traditional fuels — thus lessening demand for old tires. Read more
The smell of a burning tire is unforgettably putrid, but so far recycling technology has been unable to resurrect dead wheels. Millions and millions get discarded every year. Now a Malaysian startup says they have an answer. Read More
Moving aggressively forward in our work with tyre manufacturers in 2011. While we may be at varying stages of evaluation with several tyre manufacturers globally we are breaking into 2011 straight into tyre building trials with a major producer. This effectively means a fast forward in terms of our move to addressing the global scrap tyre problem while establishing the SRI Compound Masterbatch as a standard industrial raw material.
Devulcanized content in tires will not be about fillers and the proportions will be measured against total compound and not against raw rubber content, moving towards substantial volumes and huge strides in Cleantech. The market for fine powders will also see a major change as if they are able to maintain feedstock and purity they will suddenly become raw material of choice for devulcanization with their volumes taking a major increase with year round offtake and far less dependence on state subsidies.
