Pareto analysis is a formal Pareto analysis is a formal technique useful where many technique useful where many possible courses of action are possible courses of action are competing for attention. competing for attention.

Pareto analysis is a creative way Pareto analysis is a creative way of looking at causes of problems of looking at causes of problems because it helps stimulate thinking because it helps stimulate thinking and organize thoughts. and organize thoughts.

helps to identify helps to identify the top 20% of the top 20% of causes that needs causes that needs to be addressed to to be addressed to resolve the 80% of resolve the 80% of the problems. the problems.

There are many waste types defined by modern systems of waste management, notably including:Municipal waste includes Household waste, Commercial waste, and Demolition wasteHazardous waste includes Industrial wasteBiomedical waste includes clinical wasteSpecial Hazardous waste includes Radioactive waste, explosives waste, and Electronic waste (e-waste)

Surface water contamination: Waste that ends up in water bodies negatively change the chemical composition of the water. Technically, this is called water pollution. This will affect all ecosystems existing in the water. It can also cause harm to animals that drink from such polluted water.

Soil contamination: Hazardous chemicals that get into the soil (contaminants) can harm plants when they take up the contamination through their roots. If humans eat plants and animals that have been in contact with such polluted soils, there can be negative impact on their health.

Pollution:Bad waste management practices can result in land and air pollution and can cause respiratory problems and other adverse health effects as contaminants are absorbed from the lungs into other parts of the body.

By Pareto analysis (80/20 rule)we conclude that the major causes of garbage in cities are as follows:

Solutions

LandfillDisposal of waste in a landfill involves burying the waste and this remains a common practice in most countries. Landfills were often established in abandoned or unused quarries, mining voids or borrow pits. A properly designed and well-managed landfill can be a hygienic and relatively inexpensive method of disposing of waste materials.

IncinerationIncineration is a disposal method in which solid organic wastes are subjected to combustion so as to convert them into residue and gaseous products. This method is useful for disposal of residue of both solid waste management and solid residue from waste water management. This process reduces the volumes of solid waste to 20 to 30 percent of the original volume.RecyclingRecycling is a resource recovery practice that refers to the collection and reuse of waste materials such as empty beverage containers. The materials from which the items are made can be reprocessed into new products.

PyrolysisPyrolysis is a process of thermo-chemically decomposition of organic materials by heat in the absence of oxygen which produces various hydrocarbon gases. During pyrolysis, the molecules of object are subjected to very high temperatures leading to very high vibrations. Therefore every molecule in the object is stretched and shaken to an extent that molecules starts breaking down.

Lessons learnt

The team learnt the importance of pareto analysis when many possible courses of action are competing for attention.

We learnt the importance of Pareto diagrams in our daily lives and its utilization.

The team learnt via Pareto diagram that focusing efforts on the ‘vital few’ causes is usually a better use of valuable resourses.
