Waste disposed at the industries clusters can be recycled in a great way as it can be reused to make new products, however, if these waste are not recycled than new products are made by hauling out fresh raw material from the earth through mining and forestry process. Chemical materials like plastic, glass and aluminum can be recycled and can be used in manufacturing other products. For chemical industry, treating waste discharge is a mandatory requirement for using it to make useful products which requires innovative thinking. Aluminum which is a cheaper chemical produced using recycled and scraps aluminum instead of using ores.
Nowadays, recycled products are on augment by many consumers and major industries have adopted this stance and most of the manufacturers are facing mounting pressure to provide products from recycled materials. Carpet manufacturers are also facing this pressure. Major chemical producers such as Honeywell/Allied Signal and DSM Chemicals have developed new technology which can help to recycle approximately 1.8 million tons of nylon carpet each year. This technology allows nylon manufacturers to recover and reuse caprolactam which is a raw material used to make nylon 6.
The recycled materials used in manufacturing process considerably take less energy than required for producing new products from raw material. On the contrary, more energy is saved as extra energy is required to extort, refine, transport and process ready raw material for industry in compare with providing industry ready material.
This process of recycling diminishes the need for mining, quarrying and logging, refining and processing raw materials as each one creates substantial air and water pollution. It also helps in saving energy and cuts down greenhouse gas production which in turn embarks upon the climate change. Currently, recycling in UK has projected to save more than 18 million tonnes of C02 a year which is equivalent of taking 5 million cars off the road.
According to the Tata Strategic Management Group (TSMG) report, approximately 20% of global effluents are liable for the chemical industry, even though it accounts for only 3% of global chemicals industries. Consequently several chemical companies have started to explore green chemistry based routes of synthesis to depose wastage and optimize the usage of raw material consumption.
