Valentina Petrone, architect, environmental consultant and author of the blog "Think about sustainability", suggests how to do composting.
Unfortunately, waste disposal has a severe impact on the environment, especially for non-recyclable waste that ends up in landfills. Among these, the wet is a type of garbage challenging to manage because once landfill the food decomposes into an oxygen-free environment and produces various greenhouse gases including CO2 but above all methane, which is a gas 25 times more harmful to CO2 for the environment.
According to data collected by the association OzHarvest it is estimated that about 4 million tons of food end up each year in landfills, the equivalent of 8,400 Olympic swimming pools!
So what can we do? Very fortunately, with a little effort and changing our habits a little.
The easiest way is to start making a separate collection of the damp in your kitchen, using a washable and reusable container, and bringing the contents to associations or neighbours that already have a system for composting the damp. In Perth, for example, there are several "Community Gardens" that gladly accept food waste from private homes for free.
Another worthwhile alternative is to use the free Share Waste app that puts Australia in touch with those who want to recycle their food with people who already produce their compost and are looking for more material. Finally, there are small companies that offer the wet collection service for about $ 10 a week, and in return, they deliver every 4 months a natural fertiliser for your plants.
Hence, with a little change in our habits, each of us can better manage our waste by helping the environment a lot.
