REED: Recyclage-Energie-Dévelopement Durable on Windows Pc

Recycling is the process of converting waste into new materials and objects. It is an alternative to "conventional" waste disposal that can save materials and help reduce greenhouse gas emissions. Recycling can prevent the wasting of potentially useful materials and reduce the consumption of fresh raw materials, thus reducing energy use, air pollution (from incineration) and water pollution (from landfill).



Recycling is a key element of modern waste reduction and is the third element in the "reduce, reuse and recycle" waste hierarchy. Thus, recycling aims at environmental sustainability by substituting raw material inputs for the economic system and redirecting the waste produced.



There are certain ISO standards related to recycling, such as ISO 15270: 2008 for plastic waste and ISO 14001: 2015 for the control of environmental management of recycling practices.



Recyclable materials include many types of glass, paper, cardboard, metal, plastic, tires, textiles and electronics. Composting or any other reuse of biodegradable waste, such as kitchen or garden waste, is also considered recycling. The materials to be recycled are either sent to a collection center or retrieved from the sidewalk and then sorted, cleaned and reprocessed into new materials for manufacturing.



Strictly speaking, the recycling of materials would produce a fresh reserve of the same material. For example, used office paper would be converted to new office paper or used polystyrene foam into a new polystyrene. However, as it is often difficult or too expensive (compared to the production of the same product from raw materials or other sources), the "recycling" of many products or materials involves their reuse for the production of different materials ( for example, cardboard). Another form of recycling is the recovery of some complex product materials, either because of their intrinsic value (such as lead from car batteries, or gold from printed circuit boards), or because of their dangerous nature (for example, the removal and reuse of mercury). thermometers and thermostats)

Waste sorting can be done manually at home and collected as part of selective collection systems, or automatically separated in material recovery facilities or mechanical biological treatment systems. Manual waste sorting is the first method used in the history of waste sorting.



The waste can be solid, liquid or gaseous and each type has different methods of disposal and management. Waste management waste management concerns all types of waste, including industrial, biological and household waste. In some cases, waste can pose a threat to human health. Waste is produced by human activity, for example the extraction and processing of raw materials. Waste management - Waste management - aims to reduce the harmful effects of waste on human health, the environment and aesthetics.



Waste management practices are not uniform among countries (developed and developing countries); regions (urban and rural) and the residential and industrial sectors may take different approaches.



Much of the waste management practice is municipal solid waste, which is the bulk of waste generated by domestic, industrial and commercial activities.
