Rubber and plastic it is important for both environmental and economic reasons, there is a continuing broad based interest in recycling of scrap rubber and development of recycling technologies. The major application of scrap rubber, particularly as crumb, is outside the conventional rubber industry. More than half of the scrap is burned for its fuel value for generation of electricity and as a component in cement production. The utilization in extension of asphalt in road construction is now recognized to provide superior road performance and reduced cost. Scientists have estimated that the potential commodity value of waste plastic may be in excess of $300 per ton when used in process pathways yielding high-value chemical products or to produce electricity in efficient IGCC (Integrated Gasification Combined Cycle) processes.

Recycling wastes in agriculture is an essential disposal method, and according to waste characteristics can produce supplementary organic-matter resources (sewage sludge, compost) for crop production, or valuable soil amendments (coal fly-ash). However, since heavy-metal content in waste materials is often higher than in the soil, application rates have to be carefully controlled, to obviate the possible accumulation of toxic metals in agricultural soils. The risk of the possible pollution of crops by heavy metals makes it necessary to use guidelines for waste utilization. Food waste is food that is lost during any of the four stages of the food supply chain: (1) producers, (2) processors, (3) retailers, and (4) consumers.

Industrial and chemical waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations. Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States. In the U.S., the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), as well as state and local regulations also regulate chemical use and disposal.

Solid waste refers to the range of garbage arising from animal and human activities that are discarded as unwanted and useless. Solid waste is generated from industrial, residential and commercial activities in a given area, and may be handled in a variety of ways. Solid waste management is a term that is used to refer to the process of collecting and treating solid wastes. It also offers solutions for recycling items that do not belong to garbage or trash. As long as people have been living in settlements and residential areas, garbage or solid waste has been an issue. Waste management is all about how solid waste can be changed and used as a valuable resource.

E-Waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. The rapid expansion of technology and the consumption driven society results in the creation of a very large amount of e-waste is every minute.

Effect of 3Rs on Climate Change depends on Reduce, reuse and reuse to decrease ecological change. Natural change is any genuine change in proportions of climate, which consolidate temperature, precipitation, precipitation, snow and wind. When we use the environment as a waste dump, we take away land from wildlife, pollute the environment, and deplete natural resources. One way people are doing their part to protect the environment is adopting the Reduce, Reuse, and Recycle Waste Program.

Waste Management has made investments to put the waste we manage to reuse. In some case, that means recycling, while in other cases that means creating energy. At about 130 disposal sites, we use naturally-occurring landfill gas to power homes and businesses. Just recently, we even developed the technology to convert landfill gas into a fuel our fleet vehicles can run on. Using landfills, It has produce over 550 megawatts of electricity, which is enough to power more than 440,000 homes. This amount of energy is equivalent to offsetting over 2.2 million tons of coal per year.

Waste to Energy (WTE), is a term that is used to describe various technologies that convert non-recyclable waste into usable forms of energy including heat, fuels and electricity. WTE can occur through a number of processes such as incineration, gasification, pyrolysis, anaerobic digestion, and landfill gas recovery. Currently, the world generates 1.3 billion tonnes of Municipal Solid Waste (MSW) annually.

Used oil can be developed into lubricants, processed into fuel oils, and used as raw substances for the Refining and Petrochemical Industries. Used oil filters include reusable scrap steel, which metal producers can use as scrap feed. To recycle used oil, processors and refiners remove water, insoluble, dust, heavy metals, nitrogen, chlorine, and oxygenated compounds from oil tired from motors or other machines. The resulting product-called "re refined" oil-need to meet the identical stringent refining, compounding, and performance requirements as virgin oil for use in car, heavy-responsibility diesel and different inner combustion engines and hydraulic fluids and equipment oils.

The recycling industry has undergone changes during the last 30 years, including market fluctuations, the types of materials managed and how materials are collected and processed. European nations are at present empowering Renewable vitality from regular sources to lessen the ecological contamination.
