Fossil fuels vs. low-carbon by-product
Recycling paper is a critical part of a circular economy, an economic development strategy designed to benefit business, society, and the environment. However, the environmental benefits of recycling paper are not as straightforward as they may seem. While recycling paper saves energy, water, landfill space, and reduces greenhouse gas emissions, the process of recycling paper often relies on fossil fuels and high-carbon electricity from the grid, which can contribute to climate change.
On the other hand, the production of new paper, or "virgin paper", is powered by a low-carbon byproduct of pulping trees. Virgin paper plants burn tree waste products to cogenerate some of their energy, and the remaining part of the tree can be used to make paper. This cogeneration method means that virgin paper plants use less purchased energy from the grid. However, it is important to note that using less energy from the grid is not the same as using less energy overall. When measuring the energy consumed during paper production, recycled paper is more energy-efficient than virgin paper.
According to the Environmental Paper Network's Paper Calculator, it takes about 32 million BTUs of energy to produce one ton of virgin paper fiber. Recycling one ton of newspaper saves about 4,000 kWh (14 GJ) of electricity, which is enough to power a 3-bedroom European house for an entire year. Additionally, the Bureau of International Recycling (BIR) claims a 64% reduction in energy when paper is recycled versus paper made with unrecycled pulp.
Despite the energy savings of recycling paper, the use of fossil fuels in the process can lead to increased greenhouse gas emissions. Researchers from Yale School of the Environment and University College London (UCL) modelled various scenarios for increasing waste paper recycling by 2050 and found that if all waste paper was recycled, greenhouse gas emissions could increase by 10%. However, emissions would be significantly reduced if paper recycling were powered by renewable energy sources instead of fossil fuels.
To reduce emissions from paper recycling and mitigate climate change, a shift to renewable energy sources like wind and solar is necessary. While recycling alone is not enough to reach climate goals, combining it with renewable energy can have a profound effect on reducing emissions. Additionally, the increased demand for paper packaging, driven by the move away from plastics, will likely lead to a rise in global paper use, further emphasizing the need for sustainable paper recycling practices.

Recycling paper uses more fossil fuels than making new paper
Recycling paper is a critical aspect of a circular economy, which is an economic development strategy that benefits businesses, society, and the environment. While recycling paper can help conserve resources and reduce waste, recent studies have shown that recycling paper uses more fossil fuels than making new paper, which can lead to higher greenhouse gas emissions.
According to researchers from Yale and University College London (UCL), if all waste paper was recycled by 2050, greenhouse gas emissions could increase by up to 10%. This is because recycling paper relies more on fossil fuels and electricity from the grid, while the production of new paper uses a low-carbon byproduct of pulping trees. The study also found that modernizing landfill practices, such as capturing methane emissions for energy, had a positive impact on reducing emissions.
The researchers emphasized that recycling has benefits beyond combating global warming. For example, recycling paper can save trees, which are critical for offsetting carbon emissions. However, the extent of this benefit is unknown due to a lack of understanding of global forest carbon stocks and varied causes of deforestation. Additionally, recycling paper can conserve water, which is a critical component of energy savings.
To address the issue of increased emissions from paper recycling, the researchers suggested transitioning to renewable energy sources like wind and solar power. They estimated that this shift, combined with improved landfill practices, could reduce emissions by up to 96%. By powering paper recycling with renewable energy, the environmental benefits of recycling paper can be fully realized, contributing to a more sustainable future.
While the findings of the study highlight the importance of transitioning to renewable energy, they do not diminish the value of recycling as a whole. Recycling paper can still lead to significant energy savings compared to producing new paper from raw materials. It is important to note that reducing the use of fossil fuels in paper recycling and prioritizing renewable energy sources are crucial steps towards mitigating climate change and creating a more sustainable world.

Renewable energy sources
Recycling paper is generally considered to be environmentally beneficial. However, researchers have found that if the energy used to recycle paper comes from fossil fuels, then greenhouse gas emissions will increase. Recycling paper relies on fossil fuels and electricity from the grid, whereas the production of new paper is powered by a low-carbon by-product of pulping trees.
- Solar power: Solar energy is the fastest-growing sector in the renewable energy field. It is derived from sunlight, which is captured on solar panels in a joint chemical and physical reaction known as the photovoltaic effect. Solar energy can be harnessed even in cloudy weather and has a massive potential for growth.
- Wind power: Wind energy has been used for millennia and is the largest producer of renewable electricity in the UK and the US. It harnesses the kinetic energy of moving air using large wind turbines located on land or in water. While wind speeds vary by location, there is ample potential for wind energy deployment in most regions of the world.
- Hydropower: Hydropower is one of the oldest and largest sources of renewable energy, accounting for 28.7% of total US renewable electricity generation. It relies on the flow of water to generate energy and is found at dams, where it generates electricity through underwater turbines. Small-scale hydropower is considered more environmentally friendly as large-scale infrastructure can adversely affect ecosystems.
- Bioenergy: Bioenergy is derived from burning organic matter as fuel. Examples include vegetable oil biofuels and ethanol, which is made from corn. While these sources are considered renewable because they can be regrown, they are not the cleanest option as they require combustion and can contribute to deforestation.
- Geothermal energy: Geothermal energy utilises the thermal energy from the Earth's interior, which is produced by the breakdown of radioactive particles in the Earth's core. It can be used for a variety of purposes, including electricity generation, heating buildings, and even bathing.
