An analysis of recycling

result of recycling

Chemical recycling[ edit ] For some polymers, it is possible to convert them back into monomers, for example, PET can be treated with an alcohol and a catalyst to form a dialkyl terephthalate. Gasification is a similar process but is not technically recycling since polymers are not likely to become the result.

Analysis of recycling paper

Recycled resin demand is on the rise as prices for the two major recycled resins, PET and HDPE, continue to hold value or appreciate against their virgin counterparts. The report covers exhaustive analysis on: Market Segments. Based on this information, the processes applied in Vietnam, both in the formal and informal sector, have been analyzed systematically in terms of inputs, outputs, potential emissions and related risks for workers. Data using for calculation It is important to state that data on e-waste in Vietnam are limited as the e-waste handled is scattered among recycling craft villages [ 2 ] and by illegal importation activities [ 1 , 3 ]. The e-waste inventories in Vietnam came from works of URENCO [ 5 ] covering 7 types of appliances additional batteries and interview surveys in 7 major cities, and Nguyen et al. Uranium is a very dense metal that has qualities superior to lead and titanium for many military and industrial uses. Moreover, this production shift towards Asia Recycling operations extremely dependent on production and consumption.

However, there are several barriers hindering the implementation of effective and efficient recycling. Recently, California, Oregon and Washington have adopted bottle deposit programs, and accumulation of recyclable materials in those states has begun.

Other e-waste is shredded to pieces roughly 10 centimetres 3. With all of the cleaning and recycling plants and the majority of consumers traditionally located in the eastern part of the country, development of consumers of recycled flake and down-line products, such as film and sheet, has been slow to develop in the West.

Industrial waste materials are fed back into, and reused in, the same production process. There might be a discussion about this on the talk page.

Analysis of recycling in india

The terephthalate diester can be used with ethylene glycol to form a new polyester polymer, thus making it possible to use the pure polymer again. March It has been suggested that this article be merged with Recycling Costs. They are the easiest type of collection to establish but suffer from low and unpredictable throughput. Gasification is a similar process but is not technically recycling since polymers are not likely to become the result. Plastic Pyrolysis can convert petroleum based waste streams such as plastics into quality fuels, carbons. This article may be confusing or unclear to readers. In the recycling process, television sets, monitors, cell phones, and computers are typically tested for reuse and repaired. In , Eastman Chemical Company announced initiatives of methanolysis and syngas designed to handle a greater variety of used material. Some manufacturers are also forced to import materials from Mexico, India and South America.

Many areas which had developed source separation programs have since switched to what is called co-mingled collection. The plastics industry has developed new markets and applications for recycled resins from both post-consumer and post-industrial sources.

conclusion of recycling

Replay believes a significant answer to America's waste problem lies in creating high value, recycled thermoformable sheet and other extruded products for the packaging market. For example, Shinkuma and Huong [ 3 ] invested the e-waste illegal routes between Vietnam and China, and Vietnam and Cambodia; Nguyen et al.

Analysis of recycling of water

Recycled resin demand is on the rise as prices for the two major recycled resins, PET and HDPE, continue to hold value or appreciate against their virgin counterparts. The construction industry may recycle concrete and old road surface pavement, selling their waste materials for profit. Ships may also be sunk to create an artificial reef. Type 6 is polystyrene and makes up meat trays, egg cartons, clamshell containers, and compact disc cases. An eddy current ejects non-ferrous metals, which are sorted by density either by a centrifuge or vibrating plates. Types 1 and 2 are the most commonly recycled. Among all the aforementioned segments, tire and rubber segment is expected to witness 4. However, Iron and steel is another sub-segment of metal which is estimated to account for Levels of metals recycling are generally low. Packaging is expected to be the largest market segment for recycled plastics, with sheet and lumber following.
