Eight approaches to the problem of waste pollution

Humanity produces between 2.1 and 2.3 billion tonnes of municipal solid waste annually. 

If not handled properly, a number of waste commodities, including food, plastics, textiles, electronics, and electronics, can release hazardous chemicals or greenhouse gases. In addition to destroying ecosystems, spreading illness, and harming women and young people disproportionately, this also puts economic success in jeopardy. 

On March 30, people worldwide will commemorate the International Day of Zero Waste. Leading the observance, which highlights the importance of efficient waste management, are the UN Environment Programme (UNEP) and UN Human Settlements Programme (UN-Habitat). It also places a strong emphasis on reducing the conspicuous consumerism that is making the waste issue worse.

"Our overindulgence is killing us." "Humanity requires intervention," declares UN Secretary-General António Guterres. "Let's commit to permanently ending the waste cycle, starting on this Zero Waste Day."

The following eight techniques can help you develop a zero-waste mindset:

Address food waste

Nearly 19% of the food that is available to consumers is wasted, even while 783 million people go hungry year. Eight to ten percent of greenhouse gas emissions on Earth are attributable to the production of food that is ultimately wasted. 

There are several ways to turn that tide.

Municipalities can utilize food waste for farming, animal husbandry, upkeep of green areas, and other uses in addition to encouraging urban agriculture. In addition, they have the power to separate food waste at the source, fund food waste composting initiatives, and forbid the disposal of food in landfills. Meanwhile, consumers can buy only what they need, accept less visually appealing but still perfectly edible fruits and vegetables, store food more sensibly, use up leftovers, compost food scraps instead of throwing them away, and donate food before it goes bad thanks to a plethora of applications.

Recovery is already an option in some places. The impoverished in Vallès Occidental, Spain, receive excess food that is nutrient-rich. Meanwhile, to reduce post-harvest losses, the Adeta indigenous village in Nigeria works with the nonprofit organization No Hunger Food Bank to recycle cassava peels into animal feed.

Deal with waste textiles

Less than 1% of the material used to produce clothing is recycled into new items, resulting in an annual loss of about US$100 billion worth of material value. The textile industry uses as much water annually as 86 million Olympic-sized swimming pools.

The fashion industry needs to adapt and become more circular to counter that. Governments can set up systems for the gathering and classification of used textiles; brands and retailers can provide longer-lasting, reusable products; communicators, such as influencers and brand managers, can alter the propaganda surrounding fashion in marketing; and consumers can choose whether or not to make the necessary purchases of apparel.

Acting Executive Director Michal Mlynár of UN-Habitat states that "zero waste makes sense on every level." "We benefit our economies, our societies, our planet, and ourselves by keeping materials within the economy and improving waste management practices."

Avoid contact with electronic waste

Electronics, from computers to phones, are piling up in landfills all over the world as manufacturers continue to lure consumers into purchasing brand-new devices. 

By establishing strict regulations, governments can force manufacturers to offer repair services and encourage customers to retain their products longer, both of which would have a good economic impact. They may also implement extended producer responsibility, a law that holds manufacturers of material goods liable for the handling and disposal of waste. This can maintain goods and raw resources in the economy while promoting eco-design, garbage collection optimization, and the avoidance of consumer waste.

According to Sheila Aggarwal-Khan, Director of UNEP's Industry and Economy Division, "Humanity must act as the world drowns in waste." "We are aware of how to handle the problem of trash contamination. All we need to put them into action is commitment, collaboration, and financial assistance from institutions, businesses, and private individuals.

Produce goods with fewer resources.

The use of raw resources has more than quadrupled in the last 50 years, which has led to the depletion of natural areas and the triple global problems of pollution, waste, and climate change. 

Producers can reduce energy and resource consumption and the amount of hazardous chemicals used in manufacturing by following nationally recognized eco-design criteria. These requirements also ensure that the products are durable, recyclable, and reusable when in use. 

This should be part of a larger project to produce products with the lifecycle approach. This entails reducing the amount of resources used and emissions released into the environment across the whole life of a product, from production to recycling. 

Address the issue of plastic pollution.

Plastics are widely used in electronics, clothing, and single-use products. Roughly 85 percent of single-use plastic bottles, containers, and packaging end up in landfills or are disposed of incorrectly. Plastic has a major detrimental effect on human health since it cannot biodegrade, causing microplastics to contaminate food and water sources. 

Eliminating single-use plastics, improving waste management, and putting in place a global monitoring and reporting system are all ways to end plastic pollution. 

Deal with hazardous trash

Chemicals are found in many facets of daily life; for instance, lead can be found in cosmetics, electronics may contain mercury, and cleaning supplies typically contain persistent organic pollutants. The Basel, Rotterdam, and Stockholm (BRS) treaties stipulate particular management and disposal procedures for chemical and hazardous waste; nevertheless, some governments may not follow these guidelines. Cross-border movement of hazardous chemicals and waste is often done without authorization or even illegally.
