Waste Management

Arising quality of life, and high rates of resource consumption patterns have had a unintended and negative impact on the urban environment - generation of wastes far beyond the handling capacities of urban governments and agencies. Cities are now grappling with the problems of high volumes of waste, the costs involved, the disposal technologies and methodologies, and the impact of wastes on the local and global environment.

But these problems have also provided a window of opportunity for cities to find solutions - involving the community and the private sector; involving innovative technologies and disposal methods; and involving behaviour changes and awareness raising. These issues have been amply demonstrated by good practices from many cities around the world.

There is a need for a complete rethinking of "waste" - to analyse if waste is indeed waste. A rethinking that calls for

WASTE to become WEALTH
REFUSE to become RESOURCE
TRASH to become CASH



There is a clear need for the current approach of waste disposal that is focussed on municipalities and uses high energy/high technology, to move more towards waste processing and waste recycling (that involves public-private partnerships, aiming for eventual waste minimization - driven at the community level, and using low energy/low technology resources. Some of the defining criteria for future waste minimization programmes will include deeper community participation, understanding economic benefits/recovery of waste, focusing on life cycles (rather than end-of-pipe solutions), decentralized administration of waste, minimizing environmental impacts, reconciling investment costs with long-term goals.

1. Composting

This process involves turning food and yard waste into nutrient-rich compost that can be used as fertilizer. Composting can be done at home using a compost bin or composting machine.

2. Smart trash cans

These trash cans have sensors that can detect when the can is full and automatically compact the waste to create more space. They can also remind you to take out the trash and track your waste generation over time.

3. Recycling machines

These machines can turn plastic waste into new products, such as bottles or toys. Some machines can also crush and melt aluminum cans to make them easier to recycle.

4. Food waste disposers

These devices can be installed under the sink to grind food waste into small particles that can be flushed down the drain. The food waste can then be treated at the wastewater treatment plant and turned into biogas or fertilizer.

5. Reusable products

Using reusable products, such as water bottles, bags, and containers, can help reduce the amount of waste generated at home. There are many eco-friendly and sustainable options available on the market.

6. Smart kitchen appliances

Some kitchen appliances, such as refrigerators and dishwashers, now have smart features that can help reduce food waste and energy consumption. For example, a smart fridge can track expiration dates and suggest recipes based on the ingredients you have on hand.

7. Eco-friendly cleaning products

Using eco-friendly cleaning products can help reduce the amount of harmful chemicals that end up in landfills and waterways.

8. Zero-waste lifestyle

Adopting a zero-waste lifestyle involves minimizing waste by refusing, reducing, reusing, and recycling materials, as well as composting and utilizing waste-to-energy systems.

9. Water filtration systems

Water filtration systems can be installed in your home to purify tap water and eliminate the need for bottled water, which can create a significant amount of waste.

10. Waste-to-energy systems:

Waste-to-energy systems are small-scale systems that can convert organic waste into energy that can be used to power your home.

11. Smart bins:

Smart bins are equipped with sensors that can detect when the bin is full and automatically notify the homeowner when it's time to take out the trash. Some models also include odor-eliminating features.

12. Use tech for good

Apps are taking the fight to food waste. Olio connects neighbours and local retailers so surplus food can be shared;
Too Good To Go enables cafes and restaurants to sell uneaten meals at reduced rates; while Farmdrop connects you with sustainable local farmers. To recycle kitchen scraps, find neighbours with a compost bin (or chickens) at sharewaste.com.
