Disposal
There are no legal regulations governing the disposal of incandescent lamps, as the environmental impact of almost all substances they contain is negligible due to their nature and the amounts involved. Therefore almost all incandescent lamps are disposed of in the household waste. The disposal of compact fluorescents, however, is regulated. In 1996, the German Waste Avoidance, Recycling and Disposal Act came into effect. It places discharge-type lamps in the case of disposal and recycling into...
Styrene Economic impact and market data
Worldwide demand for styrene is estimated to be more than 20 million tons and growing by 5 annually Rohden 2001 . In 20 the styrene industry did face a 1.8 lapse in demand, but by the following year demand had again increased by 5.1 Childre 2003 . An overview of the development of styrene production is provided in Table 21 and Table 22. Table 21. Production data and capacity in Western Europe67 Styrene Production and Capacity in Western Europe 1000 tons Capacity Production Table 22. Styrene...
Variant 5 Nanoparticle clearcoat from the firm NTC
The newly developed nanoparticle coating differs in many respects from conventional coatings. The process is fundamentally different. Like traditional liquid clearcoats it consists of a binder, a liquid carrier, fillers, and additives. The binder, however, does not have the usual organic structure, but is instead a so-called inorganic-organic hybrid polymer. The nanopar-ticle coating is manufactured by means of the sol-gel process. The sol-gel process has been in existence for a long time,...
Life cycle inventory analysis Rja
In the life cycle inventory analysis, the material and energy relationships between the display technology being studied and the environment are recorded, i.e., the input flows from the environment and the output flows that are returned to the environment are noted. The goal of the life cycle inventory analysis is to establish a data inventory based on functional equivalents for the selected variants. Complete quantitative life cycle inventory data are available for the CRT and LCD. On this...
Life cycle analysis of nanomaterials
As already remarked, possible harm by nanoparticles may occur especially in environmentally open applications. A look at the life cycle of nanomate-rials reveals several points where such a release may take place 1. Nanomaterials production processes vary greatly. Industrially manufactured nanomaterials are not generally produced by combustion processes with the exception of CVD DVD and flame-assisted deposition , but mainly in liquid or closed gas-phase reactors. Therefore, direct exposure to...
Life cycle inventory analysis 1
In the life cycle inventory analysis, the material and energy relationships of the various styrene production processes are noted, with a view to possible environmental impacts, i.e. inputs from the environment and outputs into the environment are recorded. The goal of the life cycle inventory analysis is to establish a data inventory based on functional equivalents for the selected variants. Life cycle assessment data are available in summary form for traditional styrene production. The data...
