Paper, Glass, Plastic: Our Wasteful World

Plastic, paper, and glass are common materials that we interact with daily. However, they also contribute significantly to the global waste crisis. Plastic commercialization has grown exponentially since World War II, and today, the global annual production of plastic is more than 359 million tons, with about 400 million tons of plastic waste produced yearly. Paper and paperboard products made up 23.1% of Municipal Solid Waste (MSW) in 2018, while glass, plastic, and wood constituted between 4% and 5%. Despite high recycling rates for aluminum and glass, plastic recycling rates are much lower, with plastic constituting 16% of MSW combusted and 18% of MSW landfilled in 2018.

Plastic containers and packaging make up the most plastic waste tonnage

The world produces about 400 million tons of plastic waste annually, with plastic being recycled at a lower rate than previously estimated. Plastic containers and packaging make up a significant portion of this waste. In 2018, the United States generated 35.7 million tons of plastic, 12.2% of the total municipal solid waste (MSW) generated. Of this, only 2 million tons, or 13.6%, of plastic containers and packaging were recycled. This is a relatively small amount, with a recycling rate of 8.7% in 2018.

The low recycling rate of plastic is due to several factors. Firstly, plastic recycling can be more costly and energy-intensive than creating new plastic from raw materials. Secondly, misinformation is rampant, with many types of plastics being labelled as recyclable when they are not. Finally, the recycling industry itself has challenges, with initiatives receiving less support and funding, and the declining relative value of deposit amounts.

In contrast, materials like glass and aluminum have high recycling rates and can be recycled endlessly with less energy than creating new products from raw materials. Glass, in particular, is one of the cheapest and most efficient materials to recycle, made from common materials like sand and limestone. However, it is important to note that glass and aluminum packaging have a higher impact on waste management than plastic, and plastic packaging has advantages such as a lower failure rate at supermarkets.

To reduce plastic waste, it is essential to improve recycling rates and encourage the use of more sustainable materials for containers and packaging.

US citizens account for 30% of the world's paper waste

Paper, glass, and plastic waste are significant environmental concerns. The world produces about 400 million tons of plastic waste annually, with plastic recycling rates declining. Plastic waste is challenging due to its long degradation time of up to 450 years and the high cost and energy intensity of recycling.

US citizens account for a substantial proportion of global paper waste, contributing to 30% of the world's paper waste. This is a notable statistic, considering they represent only 5% of the world's population. The high paper waste in the US is attributed to various factors, including business practices and cultural preferences. Half of the waste produced by US businesses is paper, with 12.1 trillion sheets used in offices annually. Additionally, the US stores 95% of its information on paper, and the average grocery bill includes 10% for packaging, mostly paper and plastic.

To address paper waste, the US has implemented measures such as recycling and digitisation. In 2021, more than 50 million tons of paper were recovered for recycling in the US, achieving a 68% recycling rate. However, despite the availability of digital technologies, the US continues to have high paper consumption, with demand for wood pulp contributing to deforestation.

Glass waste is also a concern, with about 110 million glass bottles discarded daily in the US, of which only one-third are recycled. Glass is recyclable and can be made from common materials like sand and limestone, making it efficient and cost-effective to recycle. However, the focus of this discussion is on the significant contribution of US citizens to global paper waste.

The high level of paper waste in the US has environmental implications. Paper waste emits methane gas as it rots, contributing to climate change. Additionally, the production of paper requires significant resources, including trees, water, and oil. Reducing paper waste through recycling, digitisation, and conscious consumption can help mitigate these environmental impacts.

Glass packaging has the highest glass recycling rate

Glass packaging has proven to be more environmentally friendly than plastic packaging. Glass has a higher recycling rate than plastic, and it is one of the cheapest and most efficient materials to recycle. Glass is made from common materials like sand and limestone, and melting used glass saves 35% of the energy required to make glass from raw materials. In 2018, the glass collection for recycling rate in the EU28 was 76%, with the majority of recycled glass being used to make new bottles and jars. This makes glass the most recycled closed-loop packaging material in Europe and probably the world.

Glass packaging is also more environmentally friendly than plastic packaging because it can be recycled endlessly without degradation in quality or purity. On the other hand, plastic cannot be repeatedly recycled without quickly degrading in quality. The total bottle recycling rate in 2020 was 27.2%, down from 28.7% in 2019. Plastic is also more challenging to recycle than glass, as it is more costly and energy-intensive to recycle plastic than to create it from raw materials.

The environmental impact of plastic packaging is further exacerbated by the fact that many types of plastics are labelled as recyclable when they are not. This misinformation has led to even lower recycling rates for plastic than previously estimated. In contrast, glass packaging helps to reduce energy use and emissions, as recycled glass is the industry's most important raw material, avoiding the depletion of natural resources.

Additionally, glass packaging has a longer lifespan than plastic packaging. For example, an aluminum can has a lifespan of about six weeks, while a glass bottle can be reused multiple times before being recycled. This means that glass packaging generates less waste overall, further reducing its environmental impact.

Overall, glass packaging has a higher recycling rate than plastic packaging, and it is more environmentally friendly due to its recyclability, energy efficiency, and longevity.

Plastic is a rapidly growing segment of municipal solid waste

Plastics generation includes durable goods and containers and packaging. The recycling rate of plastic bottles and jars was 29.1% in 2018, while the rate for HDPE natural bottles was 29.3% in the same year. However, it is important to note that many types of plastics are labelled as recyclable when they are not, and plastic recycling can be more costly and energy-intensive than creating plastic from raw materials. This contributes to the low recycling rates for plastics, which is even lower than previously estimated.

The challenges of plastic recycling have been further exacerbated by import bans in countries like China and Turkey, which previously received a significant portion of plastic waste from the United States. As a result, the total bottle recycling rate for 2020 decreased to 27.2%, down from 28.7% in 2019.

The impact of plastic waste is significant, with an estimated 400 million tons of plastic waste produced globally each year. Plastic bottles, in particular, pose a problem, with Americans using 2.5 million plastic bottles every hour. These bottles can take upwards of 450 years to degrade, and between 75 and 199 million tons of plastic are currently in our oceans.

Paper production is the third biggest air polluter in the industrial world

Paper, glass, and plastic waste account for a significant proportion of global waste. While glass and aluminium have high recycling rates and can be recycled endlessly, plastic and paper cannot be recycled as effectively. In fact, the world produces about 400 million tons of plastic waste each year, and plastic recycling rates are declining. Paper is one of the most commonly recycled materials, with a 68% recycling rate in 2021. However, the paper industry is still a major contributor to air pollution.

The pulp and paper industry is a major contributor to water pollution as well. In 2015, the industry in Canada released 5% of total industrial waste into the water. Pulp and paper mills are associated with emissions of heavy metals, and in the United States, the industry is responsible for 9% of industrial releases into water. Additionally, wastewater from the paper industry may be polluted with organochlorine compounds, which are highly toxic and can have detrimental effects on human health.

To reduce their environmental impact, the pulp and paper industry is moving towards sustainability. Efforts are being made to reduce clear-cutting, water use, greenhouse gas emissions, and fossil fuel consumption. The industry is also working to clean up its influence on local water supplies and air pollution. Environmental product declarations and scorecards, such as the Paper Calculator and the Environmental Paper Assessment Tool (EPAT), are available to evaluate the environmental and social performance of paper products.

Overall, while paper, glass, and plastic waste are significant contributors to global waste, paper production, in particular, stands out as the third biggest air polluter in the industrial world. The industry's high emissions of carbon dioxide and other pollutants underscore the urgency to implement sustainable practices and reduce emissions to mitigate climate change.
