What You'll Learn
Recycling reduces the need to harvest new raw materials
Recycling is the process of collecting and processing materials that would otherwise be thrown away and turning them into new products. Recycling reduces the need to extract resources such as timber, water, and minerals for new products.
Recycling conserves energy. For example, recycling just 10 plastic bottles saves enough energy to power a laptop for more than 25 hours. Recycling one ton of paper can save 17 trees and 7,000 gallons of water. This doesn’t just save trees but also the energy used in the process of cutting, transporting, and processing the logs. Recycling paper reduces the demand for tree cutting, which is vital in maintaining our planet’s carbon balance. Trees absorb CO2, and when they are cut down for paper production, that stored carbon is released into the atmosphere. By recycling paper, we preserve forests and keep this carbon stored.
Recycling aluminum cans saves 95% of the energy needed to make new cans from raw materials. The mining and refining of aluminum from bauxite ore is highly energy-intensive and results in significant greenhouse gas emissions. In contrast, recycling aluminum requires only 5% of the energy needed to produce the same amount of aluminum from raw materials, resulting in fewer emissions.
Recycling helps to close the loop by buying new products made from recycled materials. More and more of today's products are being manufactured with recycled content. Recycled materials are also used in new ways, such as recovered glass in asphalt to pave roads or recovered plastic in carpeting and park benches.
Recycling also reduces the amount of waste sent to landfills for disposal, which preserves space and extends the life of existing landfills. It also helps to sustain the environment for future generations.

Recycling saves energy
Recycling is a crucial step in reducing pollution and saving energy. It helps conserve energy by reducing or eliminating the need to manufacture products from scratch, which is both labour-intensive and expensive. By using recycled materials, manufacturers can produce the same goods with less energy and at a lower cost. This is because recycled materials have already been refined and processed once, making the second round of manufacturing less energy-intensive.
Recycling aluminium, for example, saves up to 95% of the energy required to produce new aluminium from bauxite ore. Similarly, recycling paper uses 28-70% less energy than producing paper from virgin pulp, and recycling plastic generally requires less energy than producing new plastic products from petroleum. Recycling glass is also beneficial, as it can save 30% of the energy needed to produce new glass from raw materials due to its lower melting point.
The energy-intensive processes associated with extracting, refining, and processing raw materials are bypassed when materials like aluminium, paper, glass, and plastics are recycled. This not only saves energy but also reduces the demand for mining, logging, and drilling activities, which are harmful to the environment and marine life. Recycling helps to conserve natural resources and reduce greenhouse gas emissions, contributing to a more sustainable future.
Additionally, recycling can close the loop by buying new products made from recycled materials. This encourages the use of recycled content in manufacturing, further reducing the need for virgin materials and the associated energy consumption. Recycling also reduces pollution by diverting waste away from landfills and incinerators, minimising the harmful effects of emissions and contaminated water produced during waste disposal and energy production.

Recycling reduces greenhouse gas emissions
The production of new materials generates various forms of pollution, contributing significantly to climate change. Recycling reduces the energy used in this process, which in turn reduces the greenhouse gases emitted. This is beneficial in combating the climate crisis, as greenhouse gases are a primary driver.
Recycling inorganic waste, such as products made from natural resources like water, fuel, metal, and timber, helps reduce carbon dioxide emissions and other pollutants. Similarly, recycling plastic waste reduces greenhouse gas emissions at every stage of its lifecycle. For example, using recycled aluminium saves approximately 95% of the energy needed to produce aluminium from raw materials.
Recycling also reduces the amount of waste sent to landfills, further decreasing greenhouse gas emissions. Landfills contribute to emissions through the waste management process, including transportation and incineration. By limiting waste and increasing recycling rates, we can effectively reduce the greenhouse gases emitted by landfills.
A circular economy, which prioritizes recycling and the use of recycled materials, is key to reducing greenhouse gas emissions. This model requires less extraction of resources, generates less waste, and conserves natural resources. By adopting a circular economy, we can reduce our environmental impact and create a more sustainable future.

Recycling reduces the amount of waste sent to landfills
Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. It is an effective way to reduce the amount of waste sent to landfills and incinerators. By diverting waste from landfills, recycling helps to reduce the harmful effects of pollution and emissions.
Landfills are a significant source of environmental pollution. When waste is sent to landfills, it can release toxic chemicals and pollutants into the air, water, and soil. Organic waste, such as food scraps, decomposes and creates methane and carbon dioxide gas, contributing to greenhouse gas emissions and climate change. Inorganic waste, including products made from natural resources like water, fuel, metal, and timber, also produces greenhouse gas emissions, particularly carbon dioxide.
Recycling helps to reduce the amount of waste sent to landfills by giving new life to old materials. Recyclables are processed and turned into new products, reducing the need for extracting and processing raw materials. This not only saves energy and natural resources but also reduces the pollution associated with the extraction and manufacturing processes. For example, recycling aluminum cans saves up to 95% of the energy needed to produce new cans from raw materials, resulting in fewer emissions.
Additionally, recycling helps to reduce the amount of waste that ends up in landfills by encouraging a circular economy. In a circular economy, materials and products are kept in circulation for as long as possible through reuse and recycling. This reduces the need for extracting new resources and generating waste, as opposed to a linear economy where products are made, consumed, and disposed of.
Furthermore, recycling certain materials, such as paper, helps to reduce the demand for tree cutting, preserving forests and maintaining the planet's carbon balance. Trees absorb carbon dioxide, and when they are cut down for paper production, the stored carbon is released into the atmosphere. By recycling paper, we can help maintain the Earth's carbon cycle and reduce the amount of waste sent to landfills.
Overall, recycling is a crucial step towards reducing the amount of waste sent to landfills and mitigating the harmful effects of pollution. By reusing and repurposing materials, we can conserve natural resources, save energy, and reduce emissions, contributing to a more sustainable future.
