The Importance of Waste Diversion

Author: جورج كيرنان / Posted: 30th يوليو 2024

Waste diversion is a critical component in the effort to reduce landfill usage and promote sustainability. By redirecting waste from landfills to recycling facilities, we can conserve resources, reduce greenhouse gas emissions, and minimise the environmental footprint of waste management. This page explores various landfill alternatives and the impact of recycling on landfill reduction, aiming for a zero-waste future.

The Impact of Landfill Alternatives on Waste Diversion

Landfill alternatives such as recycling, composting, and waste-to-energy processes play a significant role in waste diversion. In 2018, the United States generated approximately 292.4 million tonnes of waste, diverting around 94 million tonnes through recycling, composting, and other food management pathways, achieving a recycling rate of 32.1%​.

In the European Union, waste management strategies have significantly evolved, resulting in the generation of 2.2 billion tonnes of waste in 2020. Of this, 1.04 billion tonnes were diverted from landfills, reflecting a recycling rate of 47%​.

Recycling: A Key Player in Landfill Reduction

Recycling is one of the most effective landfill alternatives. By processing materials such as paper, plastic, glass, and metals, recycling programmes help to significantly reduce landfill waste. In Germany, the total waste generated in 2018 was 417.2 million tonnes, with a recycling rate of 66%, diverting approximately 275.4 million tonnes from landfills​.
 
In the United Kingdom, 222.2 million tonnes of waste were generated in 2018, with a recycling rate of 44%, diverting approximately 97.8 million tonnes from landfills​​. Japan generated 42.74 million tonnes of waste in 2019, with a recycling rate of 20%, diverting approximately 8.5 million tonnes from landfills​.
 
The Middle East, in general, had an estimated total waste generation of around 150 million tonnes in 2019, with an approximate recycling rate of 10%, diverting about 15 million tonnes from landfills​.

Benefits of Recycling in Achieving Zero Waste Goals

Achieving zero waste means more than just reducing the amount of waste sent to landfills; it involves redesigning the entire life cycle of products to minimise waste and maximise reuse. Recycling is a cornerstone of the zero-waste philosophy. It not only diverts waste from landfills but also supports the creation of new products from recycled materials, fostering a circular economy.

Economic and Environmental Statistics

·      Economic Impact: The recycling industry contributes significantly to the economy. In 2020,
the recycling industry in the United States alone supported over 757,000 jobs and
generated $36.6 billion in wages.
·      Resource Conservation: Recycling one tonne of paper can save 17 trees, 7,000 gallons of
water, and 463 gallons of oil.
·      Energy Savings: Recycling aluminium saves 95% of the energy needed to produce new
aluminium from raw materials.

Landfill Reduction: The Role of Policy and Community Engagement

Government policies and community engagement are crucial in promoting recycling and reducing landfill waste. Programmes such as kerbside recycling, deposit-return systems, and public awareness campaigns have proven effective in increasing recycling rates. For instance, San Francisco has one of the highest diversion rates in the world, at 80%, thanks to robust recycling and composting programmes supported by local policies.

Case Studies: Successful Waste Diversion Programmes

Several cities and countries have implemented successful waste diversion programmes that can serve as models for others:
 
San Francisco, USA: As mentioned, San Francisco diverts 80% of its waste from landfills through comprehensive recycling and composting programmes.
Sweden: Sweden recycles nearly 99% of its household waste, with less than 1% ending up in landfills. This success is attributed to a combination of recycling, composting, and waste-to-energy initiatives.
Germany: Germany has one of the highest recycling rates in the world, at 66%. The country’s Green Dot system, which requires manufacturers to take responsibility for the recycling of their packaging, has been a key factor in this achievement.

Environmental sustainability. As communities and policymakers continue to prioritise recycling and waste diversion, we can look forward to a greener, more sustainable future.
