Solid Waste Projection

Major Sectors of Waste

Basic Concepts of SWM

Waste Hierarchy –It refers to the 3Rs reduce, reuse and recycle

Polluter Pays Principle-It is a principle where the polluting party pays for the impact caused to the environment.

Management Strategies National 3R Strategies: The national 3R

goal for waste management is to achieve higher levels of waste reduction, reuse, and recycling

Objectives of the National 3R Strategy: Address the key issues of waste

management Define the roles of various actors Guide the creation of enabling conditions

for success

Priority Sector for 3R: Municipal solid waste Industrial waste Biomedical waste Agricultural waste

3R Related Policy Guidelines

Policies-Adopted 6 policies (1998-2008) Acts -Enactment of 2 acts (1995-2006) Rules Strategies-•Adopted 4 rules

(1997-2010) Strategies -Promotion of 3 strategies

(2005) Action Plans-Promoted 3 action plans

(1995-2005)

Few Examples of Good Practices

Who’s Responsible?

The owners, operators, and/or occupants of any premises are responsible for the satisfactory and legal disposal of all solid waste generated or accumulated on the property.

Groups at risks due to solid waste

The groups at risk from the unscientific waste disposal include:

Populations in areas where there is no proper waste treatment method.

children Waste workers Populations living close to waste dump Animals

Impacts of solid waste on health:

Chemical poisoning through chemical inhalation

Uncollected waste can obstruct the storm water runoff resulting in flood

Low birth weightCancerCongenital malformationsNeurological disease

PREVENTIVE MEASURES:

Proper management of solid waste Involving public in plans for waste

treatment and disposal Provide the public accurate, useful

information about the whole projects, including the risks and maintain formal communication with public

Educate people on different ways of handling waste.
