Urban waste processing must change radically. Current legislation is based on a linear economy: from raw material to product to waste. The waste is not reused here, but destroyed. This is not sustainable in the long term. Subsequent generations will be faced with polluted soil, air and oceans, resulting in climate change, among other things. In addition, there are simply not enough raw materials for the future. Up is up.
Many cities and companies are busy with the transition to a circular economy. Waste processing plays an important role in this. Here are some ways to improve urban waste management.
These innovative bins contain sensors that monitor how much waste is in the bin. In addition, they compress the waste, so that about eight times more waste fits in it than in ‘normal’ containers. When the bin is full, a wireless signal is forwarded to the software system, which then creates an optimized collection route. This has the advantage that fuel, time and therefore costs are saved. In addition, illegal dumping of waste is prevented, because the residents of the city are not confronted with overfilled containers. Most ‘smart bins’ run on solar energy, this is for example if you lease a mr. fill bin. Several startups have further developed the idea, each with its own subtle twist. Examples include Enevo, Bigbelly and Ecube Labs.
Organic waste can be partly converted into biogas by means of anaerobic digestion. This gas can again be used as fuel. An example of application is HomeBiogas, a biogas system for families. The idea: you throw your organic waste in on one side of the container, a little later biogas and liquid manure comes out. The biogas produced can be used for cooking, for example. On a larger scale, the concept of anaerobic digestion could be interesting for the generation of green energy.
