Waste is a material, substance or byproduct eliminated or discarded as no longer useful or required after the comletion of a process.
Waste is one of the most challenging problems that humanity is currently facing.
Along with the industrial revolution, technology has developed gradually and in the meantime, waste production has increased rigorously. Technology, heavy industry and production got ahead, so as the waste production. Due to these developments in the industry, waste disposal became the common problem of humanity.
World population is expected to reach 7.7 billion by the end of 2020. Arbitrary and unplanned urbanisation can cause public spaces’ and natural resources’ impairment, air and water pollution and excessive waste production.
Rapid population growth, industrial developments and urbanisation brought the “waste” problem within themselves. Due to this problem, waste management system (collection, transportation and disposal of waste) in big cities cannot process seamlessly, it needs extra effort to keep our environment clean.
There are mainly 3 types of waste;
Household waste ( domestic waste / municipal solid waste)
Commercial Solid Waste
Industrail solid waste
What we throw away does not go away...
Non biodegradable products like plastic, metal and glass stay on the planet for up to 4000 years.
8 billion plastic bags are used and disposed of annually in the world
2.2 billion tons of waste is produced annually
90% of the things we buy are thrownaway as waste in just 6 months
50% of the waste comes from single-use products
12% of landfills consist of textile waste where 95% of textile waste is recyclable.

The world generates 2.01 billion tonnesof municipal solid waste annually,with at least 33% of that is not managed in an environmentally safe manner.
Worldwide, waste generated per person per day averages 0.74 kilogram but ranges widely, from 0.11 to 4.54 kilograms.
Though they only account for 16% of the world’s population, high-income countries generate about 34 percent, or 683 million tonnes, of the world’s waste.
When looking forward, global waste is expected to grow to 3.40 billiontonnesby 2050. ( Worl Bank Group "A Global Snapshot of Solid Waste Management to 2050")
More than one-third of waste in high-income countries is recovered through recycling and composting.
80% of the water pollution is caused due to domestic sewage like throwing garbage on open ground and water bodies. – Conserve-energy-future.com)
1 liter of waste oil can contaminate 1 million liters of water.
A nickel cadmium battery can contaminate up to 600.000 liters of water.
