Waste Management Strategies (group 02)

Waste Management Strategies



Waste management is the process of collection, transportation, and disposal of garbage, sewage, and other waste products. Waste management encompasses management of all processes and resources for proper handling of waste materials, from maintenance of waste transport trucks and dumping facilities to compliance with health   codes and environmental regulations.

  1. 3R Strategy 
  • Reduce


Reduce is to make something smaller or use less, resulting in a smaller amount of waste. “Source reduction” is reducing waste before you purchase it, or by purchasing products that are not wasteful in their packaging or use.A key part of waste“ reduction” is “conservation” – using natural resources wisely, and using less than usual in order avoid waste. You can reduce the amount of waste you create by choosing what rubbish you throw away. 

  • Reuse


Reuse is to use again or more than once. Reuse materials and items so that they have longer life spans and do not get thrown away after the first use. Many items found around the home can be used for different purposes. So before you throw those items away, think about how they can be reused.

  • Recycle


Recycle is to convert materials\waste into reusable material. Landfills are full of items that could be recycled. Recycling puts objects through a process that allows them to be used again


2. Waste Management Hierarchy



The 3R – reduce, reuse and recycle are meant to be a hierarchy, in order of importance. Waste hierarchy classifies waste management strategies according to their desirability. The aim of the hierarchy is to extract the maximum practical from products are to generate the minimum amount waste.

3. Extended Producer Responsibility ( EPR)



A strategy designed to promote the integration of all costs associated with products into the market price of the product. Cost related to whole life cycle of products are considered. Firms which manufacture, import and\or sell products are required to be responsible for the products after their useful life as well as during manufacture. EPR shifts responsibility for waste from government to producers, importers and\or sellers. Generally financial incentive are provided by the government to encourage manufacturers to design environmental friendly products. EPR may take the form of reuse, buy – back, recycling program or energy production from waste materials.

4. Polluter pays principle (PPP)



The “Polluters Pays” principal is the commonly accepted practice that those who produce pollution should bear the costs of managing it to prevent damage to human health or the environment. For instance, a factory that produces a potentially poisonous substance as a by product of its activities is usually held responsible for its safe disposal.

This principle underpins most of the regulation of pollution affecting land, water and air. Pollution is defined in UK law as contamination of the land, water or air by harmful or potentially harmful substances.

Part of a set of boarder principles to guide sustainable development worldwide (formally now as the 1992 Rio Declaration), the polluter pays principle has also been applied more specially to emissions of greenhouse gases which cause climate change.

5. Precautionary Principle



If an action or policy has a suspected risk of causing harm to the public or to the environment, I the absence of scientific consensus that the action or policy is harmful, the burden of proof that it is not harmful falls on those taking the action.

6. Product stewardship



Product stewardship is an environmental management strategy that means whoever designs, produces, sells, or uses of product takes responsibility for minimizing the product’s environmental impact throughout all stages of the products’ life cycle, including end of life management. The greatest responsibility lies with whoever has the most ability to affect the full life cycle environmental impacts of the product. This is most often the producer of the product, through all within the product chain of commercial have roles.

7. Proximity Principle



The principle of proximity is the tendency for people to form social relationships with individuals who are physically closer to them. Proximity means how close an object or person is physically to you. Someone sitting next to you on a bench is closer is proximity than a person sitting three rows away. The principle of proximity shows that individuals are more likely to form social relationships with people who are closer in proximity to them. You are much more likely to be friend your neighbor or coworker because you are exposed to them more so than a person who lives further away or who works at another place. People who are around each other more are more likely to develop a social relationship.
