Innovations inWASTE MANAGEMENT

INTRODUCTION

What is waste management?

Waste management in simple words means

collecting waste products, transporting it and processing it into a new product or decomposing it for

good

LANDFILL INCINERATOR

conventional METHODS OF WASTE MANAGEMENT

COMPOSTING

Mechanical TREATMENT And Recycling

PYROLYSIS GASIFICATION

Rapid development and industrialisation Increase in population

Increase in waste generation

Many landfill sites reaching capacity

THE NEED FOR innovativeWASTE MANAGEMENT

New types of waste such as e-waste or WEEE becoming new threats

dumped by developed nations in developing nations; violation of humanrights

Price of land significantly increase

Increase in pollution due to harmful emissions and contaminated and littered water bodies

NEW TECHNOLOGIES AND ALTERNATIVE SOLUTIONS

LANDFILL BIOREACTOR

'Controlled land filling' process

controlled additions of liquid and leachate recirculation

accelerates the decomposi-tion process of waste

enhances the growth of the microbes responsible for waste decomposition

Conventional landfills keep waste as dry as poss-ible; delays decomposition

covered with plastic membrane to prevent escape of land fill gas

Reliable energy generation

reduced pollution threat; reduction of greenhouse gas emissions

landfill life extension; reduced post-closure maintenance

MICROWAVE PLASMA GASIFICATION

organic and other waste heated by microwaves- heavily ionises; forms plasma cloud

organic substances are combusted and transformed into a syngas;

gas provides enough energy to power microwaves

only 20% of the recovered energy

metals, glass and minerals not gasifiable; melted into an inert slag residue

recyclable by-product; building material; very light; mouldable 60% more efficient; can produce diesel from waste; produce 70% diesel as a by-product

Strains of bacteria capable of breaking down plastics into biodegradable polymers

Isolated from soil samples collected from recycling plants

Polyhydroxyalkanoates (PHAs) synthesized by bacteria in high carbon sources or nutrients e.g., nitrogen, phosphorous, sulphur, oxygen

PLASTIC DEGRADING BACTERIA

Plastic carry bags, blood bags and plastic granules completely degraded

Similar properties to poly-Ethene and polypropylene

PHAs an environment friendly alternative to petrochemical-based plastic

Applications in packaging, coating materials, medical equip-ments

No trash sent to landfills, incinerators, etc.

smarter designs for products; to become resources

New rules and policies- responsible approach to using and conserving natural resources change in attitudes, lifestyles and practices

ethical, economical, efficient and visionary; creates jobs

ZERO WASTE PHILOSOPHY
