Harare's Plastic And Paper Waste: A Troubling Issue

Paper waste and plastic waste are significant global issues, with plastic waste being particularly problematic. The world produces about 400 million tons of plastic waste a year, and plastic recycling rates are low due to the cost and energy intensity of the process. Paper waste is also a concern, with more than 400 million metric tons produced annually, and while paper is one of the most commonly recycled materials, not all waste paper is properly recycled or disposed of. Businesses and schools are major contributors to paper waste, and improper disposal can have economic and environmental impacts. This waste issue is not limited to paper and plastic, as other materials such as glass, metal, and electronic waste also contribute to the global waste problem.

Paper waste is often overlooked, but it can have a significant impact on the economy and environment

While plastic waste has been at the forefront of global waste disposal concerns, paper waste remains a significant issue that is often overlooked. The impact of paper waste on the economy and the environment is substantial, and it is important to address it.

Paper waste can have a notable economic impact, particularly for businesses. Research by Gartner suggests that paper waste can account for between 1% and 3% of a company's revenue, with printing errors, equipment maintenance, and inefficient use of paper contributing to the high costs. For example, printing mistakes and cartridge leaks can lead to unnecessary expenses, as the typical response is to discard the paper and print again. In addition, a significant portion of printed materials, such as meeting agendas and presentations, are often discarded shortly after use. This waste can be reduced by adopting digital alternatives, such as electronic storage and paperless transactions, and by implementing simple measures like double-sided printing and reducing font and margin sizes.

The environmental consequences of paper waste are also significant. The global paper industry relies on more than 100 million hectares of forests annually, contributing to net deforestation and carbon emissions. While some paper is sourced from sustainably managed forests, other ecologically important forests are exploited, leading to a loss of biodiversity. Additionally, the manufacturing process of paper products generates waste in the form of offcuts and trimmings, which, if not properly recycled and reused, can further contribute to environmental degradation.

Furthermore, improper paper waste disposal exacerbates the problem. In 2019, about 56% of the estimated 110 million metric tons of paper and cardboard waste in the United States was landfilled, with only 38% recycled. This waste constitutes a substantial portion of municipal solid waste and includes items such as newspapers, magazines, books, napkins, junk mail, and packaging. The embodied energy required to manufacture and dispose of this waste is considerable, and the economic and environmental value of these resources is lost when they are landfilled.

However, it is important to recognize that paper waste recycling has gained momentum, with environmental advocates pushing for it for years. Paper is recyclable and reusable, and proper waste management strategies can help retain the value of the resources used in paper production. Recycling paper saves trees, reduces water consumption, and decreases the amount of other resources required in the paper-making process. Additionally, some paper mills have adopted sustainable practices, such as recycling and reusing water, to minimize their environmental impact.

Paper is one of the most frequently recycled materials, but not all waste paper is recycled properly

Paper is one of the most frequently recycled materials, with a recycling rate of 68.2% in 2018, the highest compared to other materials in municipal solid waste (MSW). In 2021, more than 50 million tons of paper were recovered for recycling, maintaining a 68% recycling rate. However, not all waste paper is recycled properly.

In 2019, of the estimated 110 million metric tons of paper and cardboard waste thrown out across the United States, approximately 56% was landfilled, 38% was recycled, and the rest was burned. This category of waste constituted about a quarter of MSW and included items such as newspapers, magazines, books, napkins, junk mail, photographs, pizza boxes, and milk cartons. The U.S. is one of the world's top waste producers, and most of it goes to landfills, resulting in the loss of valuable resources and energy that could be recovered through proper waste management.

Businesses are a significant contributor to paper waste, with around 50% of all waste produced by businesses being paper. This is due to factors such as printing errors, disposing of company documents, and packaging waste from deliveries. Schools also generate considerable paper waste, with the average primary school student producing about 45 kg of waste paper and each secondary school student creating around 22 kg.

To reduce paper waste, individuals and organizations can take several measures. These include double-sided printing, utilizing digital media and cloud-based applications, and practicing proper waste segregation and recycling methods. By implementing sustainable waste management practices, the economic and environmental benefits can be significant.

While paper recycling is generally successful, it is important to note that not all waste paper is properly recycled or disposed of, contributing to environmental and economic impacts.

The global paper industry uses more than 100 million hectares of forest annually, contributing to net deforestation and carbon emissions

The global paper industry is a major consumer of forest resources, with significant environmental implications. Each year, the industry utilises over 100 million hectares of forest, contributing to the ongoing issue of deforestation and the associated release of carbon emissions.

Forests play a crucial role in maintaining the Earth's climate and supporting biodiversity. They cover nearly a third of the planet's land area and are home to the majority of terrestrial species. Additionally, forests act as carbon sinks, absorbing carbon dioxide from the atmosphere and storing it as carbon in trees and soil. This process helps mitigate climate change by reducing the concentration of greenhouse gases.

However, the global paper industry's high demand for wood contributes to the loss of forests worldwide. Between 1990 and 2020, approximately 420 million hectares of forest were lost, with an annual rate of 10 million hectares between 2015 and 2020. This deforestation is primarily driven by the demand for agricultural commodities, with agribusinesses clearing land for cash crops and cattle ranching.

The paper industry's contribution to deforestation has consequences for the climate. When forests are cut down or burned, they release stored carbon back into the atmosphere as carbon dioxide, adding to the greenhouse effect. This release of carbon can turn forests from carbon sinks into carbon sources, exacerbating climate change.

To address the environmental impact of the paper industry, it is essential to promote sustainable practices and reduce waste. Recycling paper can help conserve resources and decrease the demand for new wood. Additionally, initiatives like the World Wildlife Fund's (WWF) Forests Forward program aim to identify legal and sustainable sources of timber, encouraging responsible forest management. By implementing such measures, we can work towards mitigating the industry's contribution to deforestation and carbon emissions.

Businesses are a major contributor to paper waste, with around 50% of their waste being paper

The impact of paper waste on the economy and the environment is significant and should not be taken for granted. Improper paper waste disposal and recycling can impact the economy, with the high costs of inefficient paper use being difficult to ignore. Research by Gartner suggests that paper waste can take up between 1% and 3% of a company's revenue. Furthermore, a separate report found that 17% of all things printed amount to nothing but waste. With the right waste-management strategies, companies can retain the value of their paper waste.

Paper waste also has environmental consequences. The global paper industry is fed by more than 100 million hectares of forests annually, contributing to net deforestation and carbon emissions. While much paper is sourced from sustainably managed forests, some is made from trees in ecologically important forests, leading to a loss of biodiversity. Additionally, the embodied energy—the energy required to manufacture paper waste—equated to 9% of what the US industrial sector used in 2019.

However, recycling paper has proven to be successful. Paper is one of the most frequently recycled materials, and more than 50 million tons of paper were recovered for recycling in 2021, achieving a 68% recycling rate. Recycled paper saves trees and drastically reduces the amount of other resources used in the paper-making process, such as water and electricity. For example, recycling paper saves between 3000 and 4000 kWh of electricity and around 30,000 litres of water.

Schools in the USA use up to 32 billion sheets of paper a year, with the average primary school student producing about 45kg of waste paper

Paper is one of the most commonly recycled materials, and recycling programs for paper have proven successful. In 2021, more than 50 million tons of paper were recovered for recycling globally, achieving a 68% recycling rate. However, not all waste paper is recycled and discarded properly.

The high paper consumption in schools is due to various factors. In the digital age, paper remains essential for educational purposes, such as exercise books, handouts, printing, documents, art materials, and classroom displays. Almost all school paper is recyclable, and schools should have specific paper bins to facilitate recycling. However, only 20% of recyclable waste generated by schools is recycled.

Primary schools generate around 45kg of waste per pupil annually, while secondary schools produce about 22kg of waste per pupil. Combined, primary and secondary schools in the UK produce an estimated minimum of 180 million kg of waste each year. Food waste is a significant contributor, with vegetables being the most wasted item, accounting for half of all food waste.
