Paper recycling process
The paper recycling process has several benefits, including saving waste paper from occupying homes and producing methane as it breaks down. It also keeps carbon, which is contained in paper fibre, locked up and out of the atmosphere.
Paper recycling involves several steps. Firstly, the collection of used paper is the first step in the process. It is important to note that paper for recycling needs to be gathered separately from other waste, as contaminated papers are not suitable for recycling.
Once collected, the paper is transported to a materials recovery facility (MRF) to be sorted and measured. At this stage, contaminants are removed, and paper is separated from other recyclable materials. The paper is then baled and sent to a paper mill, where the recycling process truly begins.
At the paper mill, the paper is shredded into small scraps and mixed with large amounts of water and chemicals to break it down into separate paper fibres. This mixture is known as pulp, the raw material used to make recycled paper. The pulp is then de-inked and passed through rollers to squeeze out the excess water. The pulp is then heated to form long rolls of continuous sheets of paper, which are then sent to manufacturers to be made into new paper products.
It is important to note that the quality of paper decreases each time it is recycled, as the fibres break down. Therefore, a higher percentage of new fibres must be added, or the paper is down-cycled into lower-quality products.

Plastic recycling process
Plastic recycling is the process of converting plastic waste into other products. It helps to reduce dependence on landfills, conserve resources, and protect the environment from plastic pollution and greenhouse gas emissions. However, it is important to note that recycling rates for plastics lag behind those of other materials such as aluminium, glass, and paper.
The plastic recycling process can be broadly divided into the following steps:
Collection
Collectors from the government or private companies gather all post-consumer plastic materials from various sources, including homes, schools, and other institutions.
Sorting
Sorting is done to group plastics into their respective types. This step is crucial as different types of plastics need to be processed separately. Sorting can be done manually or by machines at recycling plants, based on factors such as chemical composition, colour, thickness, and intended usage.
Washing
The sorted plastics are then washed to remove impurities such as product labels, adhesives, and food residue that may disrupt the recycling process.
Shredding
The washed plastics are then broken down into smaller-sized pieces, which can be used as additives or sold as raw materials. Shredding also helps remove additional impurities like metals.
Melting and Pelletizing
The shredded plastic is then melted and formed into pellets or "nurdles". This step may involve filtering to remove small solids and processing with special equipment.
Moulding
Finally, the pellets are moulded into new products. The specific process may vary depending on the type of plastic and the intended end product.
It is important to note that some types of plastic, such as PVC, are rarely recycled due to their toxicity during processing. Additionally, products made from a combination of plastics or mixed materials may not be recyclable in most facilities.

Environmental impact of paper recycling
Paper recycling is the process by which waste paper is turned into new paper products. It is an important part of sustainable development and has several environmental benefits. Firstly, it saves waste paper from occupying people's homes and producing methane as it breaks down. Recycling also keeps carbon locked up for longer and out of the atmosphere, as paper fibre contains carbon originally absorbed by the tree from which it was produced.
Recycling paper uses less energy than creating new material from raw materials, and it reduces the need for raw materials. It also creates less pollution, with the United States Environmental Protection Agency (EPA) finding that recycling causes 35% less water pollution and 74% less air pollution than making virgin paper. Pulp mills can be sources of both air and water pollution, especially if they are producing bleached pulp. However, modern mills produce considerably less pollution than those of previous decades.
Recycling paper saves natural wood stock, reduces water consumption, and preserves the environment. For example, one ton of waste paper can replace approximately 2.5 cubic metres of wood. It also saves enough energy to power the average American home for six months. However, a critical issue in paper recycling is the impact of energy use in manufacturing, as processing waste paper requires energy derived from fossil fuels, which can reduce the potential environmental benefits of recycling.
The full benefits of paper recycling can only be realised if the process is powered by renewable energy. While recycling requires less energy than making new paper, it often relies on fossil fuels and high-carbon electricity from the grid. In contrast, the production of new paper is powered by a low-carbon by-product of pulping trees. If all waste paper was recycled using renewable energy, it is estimated that emissions would be reduced by 96%.
Paper recycling rates have been increasing over the years. In 2018, paper and paperboard accounted for 67.39 million tons of municipal solid waste (MSW) generated in the US, down from 87.74 million tons in 2000. As of 2018, paper products are the largest component of MSW generated in the US, making up 23% by weight. Paper is the most commonly recycled material, with 68.2% of paper waste recovered in 2018, up from 33.5% in 1990.

Environmental impact of plastic recycling
Plastic recycling has significant environmental impacts. It helps keep plastic out of streets, parks, and oceans, reducing the environmental threat posed by plastic waste. Recycling can also help minimise pollution, conserve energy, and build a more sustainable future.
However, plastic recycling is a complex process that can have negative consequences for the environment. For example, plastic waste is often exported from high-income countries to poorer parts of the world, leading to environmental injustice and potential harm to human and animal health. Additionally, the recycling process itself can release toxic chemicals, such as dioxins and endocrine disruptors, which can contaminate air, water, and food, posing risks to both the environment and human health.
Furthermore, the recycling of plastic requires careful assessment due to the presence of toxic chemicals in the original material. These chemicals can remain in the recycled plastic, potentially causing harm even after the item is recycled. The production of plastic itself has significant environmental impacts, including water pollution, global warming, resource depletion, and microplastic pollution.
Despite these challenges, recycling plastic can help reduce the demand for new plastic production, which has a significant environmental impact. It also promotes a circular economy by keeping resources in use for as long as possible, minimising waste, and encouraging the use of recycled plastic in new products.
Overall, plastic recycling has a complex environmental impact, with both positive and negative consequences. While it helps reduce pollution and conserve resources, it also faces challenges related to toxic chemicals, energy consumption, and the complex global recycling stream.

Paper and plastic recycling rates
Paper recycling refers to the decomposition and recycling of discarded paper to create new paper goods without harming trees or forests. Paper recycling has several benefits. It saves waste paper from occupying homes and producing methane as it breaks down. It also keeps the carbon locked up for longer and out of the atmosphere because paper fibre contains carbon. Recycling paper also uses less energy, creates less pollution, and reduces the need for raw materials.
Paper is one of the most commonly recycled materials. In 2018, 68.2% of paper waste was recovered in the US, up from 33.5% in 1990. The paper recycling rate has met or exceeded 63% each year since 2009. In 2021, the paper recycling rate was 68%. The recycling rate for old corrugated containers (OCC), also known as cardboard, was 93.6% in 2022, an increase over the previous year's rate of 91.4%. In 2023, the cardboard recycling rate was 71% to 76%, and nearly 33 million tons of cardboard was recycled.
The paper recycling rate in Europe was 54.6% or 45.5 million short tons in 2004. The recycling rate increased to 64.5% in 2007 and 71.7% in 2014. The industry self-initiative European Recovered Paper Council (ERPC) was set up in 2000 to monitor progress toward meeting the paper recycling targets set out in the 2000 European Declaration on Paper Recycling.
Plastic recycling, on the other hand, lags behind that of other recoverable materials such as aluminium, glass, and paper. Plastic recycling is the processing of plastic waste into other products. From the start of plastic production through to 2015, the world produced around 6.3 billion tons of plastic waste, only 9% of which has been recycled, and only 1% has been recycled more than once. Plastic recycling is more costly and energy-intensive than creating plastic from raw materials, contributing to the low recycling rates. In some countries, burning is the dominant form of plastic waste disposal, especially where landfill diversion policies are in place.

Frequently asked questions
Paper recycling is the process of turning waste paper into new paper products. Paper is chopped up, heated, and broken down into strands of cellulose, which are then strained, cleaned, de-inked, bleached, and mixed with water to create a slurry. This slurry is then used to make new recycled paper.
Plastic recycling is a more complicated process than paper recycling due to the greater variety of plastics. Plastics are sorted by resin type and sometimes by colour, then shredded, and impurities like glue and paper labels are removed. The plastic is then melted and formed into pellets, which are used to make new plastic materials.
Paper recycling has several important benefits. It saves waste paper from ending up in landfills and producing methane as it breaks down. It also keeps carbon, which is contained in paper fibre, out of the atmosphere. Paper recycling also uses less energy, creates less pollution, and reduces the need for raw materials compared to creating new paper from raw materials.
