Recycling our organic waste

Everything we throw away has value: all our rubbish can be put to good use. Today, waste separation is an essential part of our daily chores – or it should be. We already separate paper, glass, metal and plastics from our waste. Instead of going to landfill, these resources are recirculated in the economy by being used again and again: as many times as is technically possible. This is a basic building block of the circular economy that is in the process of being established. It is the future.

We also recycle electric and electronic waste. Instead of being thrown away, televisions, refrigerators, radios, computers and laptops are disassembled with most parts being reused. The circular economy should ensure, over time, that more manufactured products are made of parts that are fully reusable. This will regenerate the constituent parts of these products when their useful life comes to an end. Most electronic goods contain rare metals that we need to preserve for future use and recycling ensures that what nature has provided is put to good use.

Three years ago, Wasteserve launched a pilot project focusing on the separation of organic waste. Limited to a small number of localities, this pilot project sought to lay the foundations for a nation-wide exercise aimed at separating organic waste and this nation-wide exercise is due to be launched on Wednesday 31 October.

Organic waste accounts for approximately 50 per cent of the waste we dispose of every day in the black bag which is collected on a door-to-door basis all over the Maltese islands. Appropriate bins and white bags are now being distributed to all households, together with information on how the collection of organic waste will take place. In the white bag for organic waste we should place food left-overs, raw or cooked, as well as used teabags, used paper napkins and similar items.

Organic waste in the white bag will be collected from our doorsteps and will be taken to  the Sant Antnin Waste Treatment Plant at Marsaskala. Here, after being checked, it will be placed in a waste digester where it decomposes and produces methane gas which is utilised to produce electricity. Other important by-products produced from organic waste are heat and compost. I am informed that, during the pilot project, the heat produced was used to heat up the water in the swimming pool of the Inspire Foundation at Marsaskala which swimming pool is utilised for therapeutic swimming.

Our organic waste is, in fact, a very useful resource – and clearly shows why it is important to recycle. All our waste can be put to good use. When we recycle we avoid, or reduce, negative environmental impacts and contribute towards a better quality of life for everyone.

The results of the pilot project on organic waste, initiated three years ago, are not available for public scrutiny. We undoubtedly welcome the extensive preparations in hand to ensure that, come 31 October, the collection of the organic part of our waste proceeds as planned. However, more information is required regarding the actual results achieved so far.
