Throwing away recyclables is a topic that has gained prominence in recent years, with an increasing awareness of the environmental impact of human activities. While recycling is generally considered beneficial for the environment, there are complexities and challenges associated with the process. Recycling programs can be expensive to implement and maintain, and they may sometimes inadvertently contribute to pollution. The recycling process for certain materials, such as paper and plastic, can release harmful chemicals and pollutants into the environment. Additionally, contamination of recyclables with non-recyclable materials can render entire batches unusable. However, the alternative of not recycling also has significant drawbacks. Neglecting to recycle can lead to overflowing landfills, harmful chemical seepage into the soil, and pollution of water bodies. The key to mitigating these issues lies in a combination of approaches, including reducing consumption, reusing materials, and improving the efficiency and accessibility of recycling programs.

The environmental impact of throwing away recyclables
Throwing away recyclables instead of recycling them has several negative environmental impacts. Firstly, it increases pollution. When specific waste, such as Styrofoam, ends up in landfills, harmful chemicals can seep into the soil, potentially leading to the formation of cancerous cells. Plastic waste can also contaminate large bodies of water, including lakes, oceans, and rivers. Landfills emit carbon dioxide, methane, volatile organic compounds, and other hazardous pollutants into the air, contributing to air pollution.
Recycling helps to conserve natural resources by reducing the need to extract raw materials such as timber, water, and minerals. It also reduces greenhouse gas emissions and saves energy. For example, recycling ten plastic bottles saves enough energy to power a laptop for more than 25 hours. By diverting waste from landfills and incinerators, recycling contributes to waste and pollution reduction.
However, the recycling process itself can also have environmental drawbacks. Recycling paper requires chemicals and large amounts of water and energy. Recycling plastic can release harmful pollutants into the air and water. Additionally, the effectiveness of recycling has been questioned. Some experts argue that reducing consumption or reusing materials can be more effective in reducing greenhouse gas emissions.
The type of recyclable material also impacts the environmental consequences of throwing it away. For example, metal and glass are highly recyclable, and while not terribly environmentally harmful to discard, reusing them is more energy-efficient. On the other hand, plastic waste is a significant concern, with six times more plastic waste being incinerated than recycled. The glut of natural gas and the boom in U.S. petrochemical production have made virgin plastic cheaper than recycled plastic.
Textiles and food waste are also significant sources of waste. Only 15.2% of textiles were recycled in the U.S. in 2017, and while the fashion industry is embracing old clothing, it is not enough to solve the problem. Food waste is the most significant source of waste by tonnage, and while some cities in northern Europe have successfully used organic waste as a source of energy, the history of air pollution associated with waste-to-energy facilities in the U.S. raises questions.

The cost of recycling programs
Recycling programs can be costly, and there is some debate about whether the benefits outweigh the costs. The price of recycling is dependent on a range of factors, including the global market for scrap materials, the price of oil, and the reliance on cheap, single-use products.
In the United States, recycling is generally more expensive than simply throwing materials away. For example, in San Jose, California, it costs $28 per ton to landfill waste, compared to $147 per ton to recycle. Similarly, in New York City, for every ton of recycled goods delivered to a recycling facility, the city spends $200 more than it would to dispose of that waste in a landfill. However, it is important to note that these costs can vary depending on location and the efficiency of the recycling system. Well-run recycling programs can be cheaper than other forms of waste disposal, and some proponents of recycling argue that the environmental and health benefits of recycling outweigh the costs.
Recycling programs incur costs from various aspects of the process. Firstly, there is the cost of collecting, transporting, and sorting recyclable materials. This includes specialized trucks, additional employees, and, in some cases, the cost of purchasing and providing recycling containers to residences. Secondly, there are the costs associated with the recovery facility, such as sorting, cleaning, and processing materials into a usable state. The prices of these recycled materials can fluctuate depending on supply and demand. Additionally, recycling programs often require public relations campaigns to educate the public about which products are recyclable, further adding to the overall cost.
The high costs of recycling programs have led to a decrease in some recycling initiatives. For instance, in 2002, New York City found that its recycling program was losing money, so it eliminated glass and plastic recycling. Similarly, due to the high costs of recycling certain materials, such as plastic, some localities have resorted to incineration or landfill as cheaper alternatives.
Despite the costs, many states in the US are pushing to increase recycling rates, and there is ongoing legislation to address plastic pollution and improve recycling infrastructure. The Bipartisan Infrastructure Law, for example, aims to provide funding for state and local waste management infrastructure and recycling programs. While recycling can be costly, it is essential to consider the potential environmental and health benefits, as well as the long-term impact of waste reduction and resource conservation.

Contamination of recyclables
Recycling contamination occurs when materials are sorted into the wrong recycling bin or when materials are not properly cleaned, such as when food residue remains on a plastic yoghurt container. Contaminants turn recyclables into trash. For example, if someone throws plastic into an OCC (cardboard) stream, there's a strong possibility it's rejected and sent to a landfill, resulting in a wasted recycling effort.
Food and drink contamination is commonly found on takeout containers, greasy pizza boxes, and bottles and jars that have not been rinsed. Food waste contamination can also be found in paperboard take-home boxes full of food and the recyclable jar/can that hasn't been emptied or rinsed out. Pizza boxes are made from cardboard, but the oil from pizza often seeps into the cardboard and cannot be separated from the fibre during the pulping process. When in doubt, send your items to a landfill to avoid contaminating other materials.
Plastic bags and items made from their plastic material (i.e. shrink wrap, bubble wrap, plastic bags, newspaper bags, trash bags, etc.) are the worst recycling contaminators. They clog up recycling equipment, causing major delays and potential harm to workers at the recycling facility. Thin plastic bags are recyclable at specialized facilities.
Other items that can contaminate an entire load of recyclable materials include electronics, which contain lead, cadmium, and mercury, and are considered hazardous waste. Textiles are recyclable, but placing them in the recycling bin along with other recyclables will contaminate the designated recycling stream.
The rules and regulations regarding acceptable materials can vary from town to town, making it confusing for citizens. Checking with your local municipality on what items can and cannot be recycled is a great first step.

The effectiveness of recycling
Despite its many benefits, recycling is not a perfect solution to waste management. It has several drawbacks that impact its effectiveness. One of the primary drawbacks is the cost. Recycling programs require specialised equipment and infrastructure to collect, sort, and process recyclable materials, which can be expensive to implement and maintain. The value of recycled materials is often lower than the cost of producing new materials, making it challenging for recycling programs to be financially sustainable.
Another significant issue is contamination, which occurs when non-recyclable materials are mixed with recyclables. Contamination can render an entire batch of recyclables unusable, and it affects the profitability of the recycling industry. Inconsistent recycling practices and consumer disposal errors contribute to contamination rates, with one study finding that 25% of items are incorrectly placed in recycling bins. China's strict waste import policy, National Sword, highlights the challenge of contamination, as American recyclers struggle to meet the low contamination standards required.
Recycling has proven environmental benefits, such as reducing greenhouse gas emissions, conserving energy, and diverting waste from landfills and incinerators, thereby reducing pollution and emissions. Recycling conserves natural resources by reducing the need to extract resources like timber, water, and minerals for new products. Additionally, recycling initiatives can divert millions of pounds of waste from landfills, positively impacting the environment.
To enhance the effectiveness of recycling, it is crucial to address contamination issues, improve infrastructure, and explore alternative waste reduction strategies. Standardised metrics and strategic objectives, such as those outlined in the US EPA's National Recycling Strategy, can help create a stronger and more resilient recycling system.
While recycling alone cannot solve the waste management problem, it remains an important part of efforts to reduce waste and conserve resources. By combining recycling with other approaches like waste reduction, composting, and upcycling, we can work towards creating a healthier planet for future generations.

The alternatives to recycling
Throwing away recyclables can have several environmental consequences, such as pollution and overflowing landfills. Recycling is one way to combat these issues, but it is not the only solution. Here are some alternatives to recycling:
Reduce
The most significant way to manage waste is to reduce the amount of waste generated. This can be achieved by only purchasing goods that are needed and in the right amounts. Buying second-hand goods or obtaining substitutes can also help reduce the demand for new products.
Reuse
Instead of discarding items, they can be reused or repaired to extend their lifespan. This approach is gaining momentum in Germany, which has implemented a deposit system on bottles with a reuse rate close to 100%. Some companies also offer rental options and take back products when customers no longer want them, creating secondary markets.
Energy Recovery
Waste-to-energy is a type of incineration that creates heat and/or electricity, reducing the environmental impact of waste disposal. While incineration has been associated with toxic emissions, recovering the non-recyclable or non-reusable portion of plastics as energy could produce additional electricity compared to conventional production methods.
Composting
Composting organic waste can reduce waste and provide a source of energy. Some cities and countries in northern Europe have successfully used organic waste as a source of energy, and advancements in technology have addressed air pollution concerns.
Bio-based Plastics
Bio-based plastics are presented as a compromise to conventional plastics, but they have drawbacks. Their recyclability is questionable, and their plant origin creates a distortion in the demand for agricultural land. However, with improvements, they could become a viable alternative to traditional plastics.
While recycling is essential, these alternatives offer complementary approaches to waste management and can help reduce the environmental impact of waste disposal.
