The food waste crisis
While manufacturing as a sector is most closely associated with materials such as plastic, scrap metal, plaster, and chemicals, it’s estimated that more than two-thirds of manufacturing waste comes from biological sources. One of these is food waste, with the UK being one of the largest offenders, with more than 6.4 million tonnes of edible food being thrown away annually.
Finding solutions for manufacturers to reduce food waste is crucial to reducing the amount of waste. One method that’s been researched and confirmed for its viability is anaerobic digestion, which involves collecting and transferring the waste into a tank deprived of oxygen, breaking it down with microorganisms. Biogas is produced and can be converted into electricity generation. With 1.3 million tons of food waste broken down annually, it’s capable of powering 200,000 homes throughout the UK.
By prioritizing sending food waste to digestion plants and working to create a more circular economy within the supply chain, it can not only reduce physical waste but also help to reduce the industry's greenhouse gas emissions, protect the environment's biodiversity, and require much less energy for production.
The dangers of handling and disposing of hazardous waste
The manufacturing industry works with many other sectors, meaning that some of the waste produced can be classified as hazardous. Whether waste is hazardous or non-hazardous is covered by the European Sustainability Reporting Standard but often refers to materials that are a threat to the health of humans and the environment.
Scott Hawthorne stressed the importance of hazardous waste as an area that manufacturing must focus efforts to improve: “Within the manufacturing industry, you’re working with a multitude of sectors that can range from expired medication and needles from the medical sector to industrial solvents and asbestos. Not only can these contribute significantly to landfills, but the damage they can do to the human body and the environment should be a reason enough for the sector to keep on top of the waste produced.
“Prioritizing the safe handling and disposal of this waste will be a huge factor in the future of the sector and something that will constantly develop. This could be through emerging tech that helps to identify materials that are dangerous to human and environmental health, or auditing the sectors your business works with to mitigate the amount of harmful materials produced.”
The manufacturing sector is undergoing a significant transformation as it tackles the challenge of waste. Regulatory and consumer pressures further reinforce the importance of these efforts, making waste reduction not just an environmental imperative but a business necessity. As these trends continue to evolve, the manufacturing industry has the potential to become a leader in sustainability, setting an example for other sectors to follow.
