Recycling includes processing of used materials into innovative products so as to reduce raw materials consumption and energy use, preclude waste of useful materials, reduce water and air pollution by decreasing the demand on conventional disposal of waste, and reduce greenhouse gas emissions in comparison with virgin production.
By reduction of the quantity of energy employed by the industry, recycling can lessen greenhouse gas emissions and help repress global climate change. This happens because the great amount of energy utilised in transportation and industrial processes involves combustive fossil fuels such as coal, diesel and gasoline, which are the most significant carbon sources. Other advantages come from decreased emissions from landfills and incinerators and by slowing the harvest of trees, which are one of the carbon sinks. During 2004, greenhouse gas emissions were reduced by two million metric tonnes value of carbon equivalent because of recycling.
Besides greenhouse gases, a variety of pollutants in water and air can be reduced by recycling. By reducing the necessity of processing and extracting new raw materials from the ground, recycling can eradicate pollution related to product development’s initial stages. Examples are the extraction of material, its refinement and processing, which are actions polluting the water, land, and air with toxic materials like sulphur dioxides, methane, carbon monoxide and ammonia. Other reductions are attained by saving energy, consequently lessening greenhouse gas emissions and other air pollutants. Additionally, in studies recycling reduced air emissions by a total of 587,000 tonnes, while water emissions were reduced by approximately 9,000 tonnes.
