At present, China has accumulated 6 billion tons of garbage every year, and more than 200 cities across the country have faced the problem of waste encroaching to varying degrees. The annual domestic garbage in Guangdong Province is up to 9 million tons, and it is also increasing at an annual rate of 8%.
The Guangzhou Institute of Energy of the Chinese Academy of Sciences carries out scientific research on waste issues and seeks for a new type of comprehensive treatment and resource utilization technology for urban waste that suits China's national conditions. The first phase of this demonstration system will process 54,000 tons of domestic waste annually and produce 18,000 tons of organic compound fertilizer. The investment cost is equivalent to one-fifth of foreign technology, equivalent to 1/2 of other domestic technologies. Relevant experts believe that the completion of the system will open up new avenues for the treatment and utilization of municipal solid waste in China and have positive promotion value.
The Eameses constantly made use of new materials. The pair's first plywood chair-the Eames Lounge Chair Plastic (LCW)-made use of a heavy rubber washer glued to the backrest of the chair and screwed to the lumbar support. These washers, which have come to be called 'shock mounts', allow the backrest to flex slightly. This technology was brought back in the 670 Lounge chair. The backrest and headrest are screwed together by a pair of aluminum supports. This unit is suspended on the seat via two connection points in the armrests. The armrests are screwed to shock mounts which are connected only via glue to the interior of the backrest shell, allowing the backrest and headrest to flex when the chair is in use. This is part of the chair's unusual design, as well as its weakest link. The shock mounts have been known to tear free causing catastrophic collapse and damage.
Other creative uses of materials include the seat cushions - which eschew standard stapled or nailed upholstery. Instead, the cushions are sewn with a zipper around the outer edge that connects them to a stiff plastic backing. The backing affixes to the plywood shells with a series of hidden clips and rings. This design, along with the hidden shock mounts in the armrest allow the outside veneer of the chair to be unmarred by screws or bolts. The chair has a low seat which is permanently fixed at a recline. The seat of the chair swivels on a cast aluminum base, with glides that are threaded so that the chair may remain level.
