What is the 5R principle and should be followed as a responsible citizen?
The 5R principle of waste management is reduce,reuse,recycle,recover and residual management.In all biological waste treatment processes some surplus sludge is produced. The objective of residual management is reduction of water content, stabilization of sludge solids, reduction in sludge solids volume. Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. Recycling can benefit your community and the environment.
