Over the past few years, Malta has made encouraging progress in the field of waste management, thanks in large part to the increased effort by households in separating their waste. According to Minister for the Environment, Energy and Public Cleanliness Miriam Dalli, there has been a significant 35% reduction in the amount of mixed waste collected between 2018 and 2024. At the same time, the amount of organic waste collected has risen by an impressive 43.2% since 2022.
These statistics reflect a growing environmental awareness and a positive shift in behaviour among Maltese residents. "This shows that the people are making a tremendous effort, and we must continue moving in this direction," Minister Dalli said in an interview with The Malta Independent on Sunday earlier this month. She also highlighted the need for further investment in technology to support these efforts, underlining that progress in waste separation must go hand in hand with better infrastructure.
The separation of waste at home is one of the simplest yet most powerful ways individuals can contribute to a more sustainable environment. When waste is sorted correctly - separating recyclables, organics, and non-recyclables - it becomes significantly easier to process and reuse materials, drastically reducing the volume of rubbish sent to landfills.
Landfills are not just unsightly; they pose serious environmental and health risks. When organic waste is dumped into landfills, it decomposes without oxygen, producing methane - a greenhouse gas over 25 times more potent than carbon dioxide in trapping heat in the atmosphere. This contributes directly to global warming. Furthermore, landfills can leach harmful chemicals into the soil and groundwater, endangering ecosystems and public health.
By separating waste at the source - in our homes - we take a crucial step in breaking this destructive cycle. Organic waste, for instance, can be composted and turned into valuable soil nutrients instead of rotting away in a landfill. Similarly, recyclable materials such as paper, plastic, glass, and metal can be processed into new products, reducing the need for virgin raw materials and saving energy in the process.
The rise in organic waste collection in Malta points to an increased use of the organic waste bin. This change not only lessens the burden on landfills but also allows for the production of compost and biogas, further contributing to a circular economy.
However, there is still much work to be done. While the 35% decrease in mixed waste is significant, it also highlights that a substantial portion of household waste continues to be discarded improperly. Education and accessibility remain vital components of this ongoing effort. People need to understand not just how to separate their waste, but why it matters.
Minister Dalli's call for technological investment is well placed. Innovations such as smart waste tracking, improved recycling facilities, and public awareness campaigns supported by digital platforms can help maintain and accelerate current trends. Technology can also play a role in monitoring compliance and providing feedback to households and communities on their waste management performance.
Ultimately, reducing landfill use and creating a cleaner environment depends on both systemic support and individual responsibility. Every household has a role to play, and every correctly sorted bag of waste is a step toward a healthier planet. The changes observed between 2018 and 2024 show what is possible when communities unite for a common cause. Now, more than ever, we must build on this momentum.
