[Biology Class Notes] on MCQs on Solid Waste Management Pdf for EXAM

Posted on by engineerLeave a comment

Solid-waste management is a process of collecting, disposing, and treating solid material that is discarded because it has served its purpose or is no longer useful. An improper municipal solid waste disposal can create unsanitary conditions. In turn, these conditions can lead to environmental pollution and to outbreaks of vector-borne disease -which are the diseases spread by insects and rodents. Solid-waste management tasks present complex technical challenges. Also, they pose a wide range of administrative, social, and economic problems that must be managed and solved.

Solid waste management also offers solutions for recycling items that do not belong to trash or garbage. As long as the people have been living in residential areas and settlements, solid or garbage waste has been an issue. Waste management is all about how solid waste can be converted and used as a valuable resource.

Solid waste management should be adopted by each and every household, including business owners across the world. Industrialization has induced a lot of good things and as well as bad things. One of the adverse effects of industrialization is solid waste creation.

There are various methods that are planned towards waste management, and on this common issue, some solid waste management micro-projects have also been introduced by many of the experts. Vegetative segregation is also one among them where it results from partitioning of cytoplasmic organelles and from random replication.
