The linear model of our economy follows a take-make-use-waste path as a result of which we extract resources from the earth which we use and subsequently throw away. In contrast to this cradle-to-grave trajectory, the circular economy seeks cyclical sustainability.

In a circular economy, the management of waste is paramount. It seeks to retain the resources used in our products in the economic loop as it is considered that they can be re-used to form other products. William McDonough and Michael Braungart describe this as a cradle-to-cradle process in their seminal book Cradle to Cradle. Remaking the way we make things. This is in contrast to the throw-away society, which follows the cradle-to-grave path.

This not only makes environmental sense, it also makes economic sense. Malta’s Waste Management Plan for the period 2014-2020 tentatively points in this direction by establishing a zero waste target that is to be achieved by 2050. Thirty-three years may seem to be too far away but, in reality, it may be just enough to change our mindset. A lot of hard work is involved but, at the end of the day, it will also be rewarding.

It involves the application of what is known as the waste hierarchy to different waste streams. Waste minimisation or prevention is always the preferred option. Ideally we should aim to prevent the generation of waste and in a number of cases this can easily be done. For example, we can prevent the generation of a substantial portion of organic waste by giving more thought to the food intake in our homes. We can also reduce the amount of food packaging by opting for more fresh food – which is generally local.

Obviously, most of us have very little time to think about the consequences of our large number of small decisions which end up generating a lot of waste. Convenience generally wins the day, as we often opt for packaged and processed food. As a result, we not only generate avoidable waste but also end up eating less healthy food.

A pilot project related to organic waste is currently under way in eight localities in Malta and Gozo. It has been going for some time and although information as to the manner in which the localities involved have reacted is not publicly available, it is known through the grapevine that this has been varied but is improving.

Collecting the organic waste part of domestic waste, if carried out successfully, may well reduce the amount going to landfill by around 50 per cent. There is also an added benefit: when the organic part of our waste is processed in a waste recycling plant, the resulting gases are used to produce electricity instead of adding to greenhouse gas emissions. This is surely a win-win situation.

Reducing 50 per cent of our waste through the responsible management of just one part of it is very good policy. However, this requires much more investment in environmental education in our localities. Wasteserve, being ultimately responsible for waste management in the Maltese Islands, has taken a lot of initiatives in this respect, but much more needs to be done. It is never enough. Waste is a collection of discarded resources and realising the value of what we throw away is, in reality, what the circular economy is all about – hence the target of a zero-waste society.
