Garbage disposal seen from above
A garbage shredder is an appliance that shreds garbage to facilitate disposal. There are domestic and industrial models for hotels.
This appliance is usually placed in the sink and shreds the organic waste (food waste) by an electric motor and evacuates it through the drain using the tap water. The rest of the waste (plastics and cardboard) should be taken to traditional places (whether separative or not).
It is more comfortable because you do not need to throw away organic waste. It requires less use of the garbage collection system, which is an economic benefit for the communities and town halls, since up to 45% of the total waste is eliminated. In addition, it helps the effective separation of waste.
In general terms, the household crushing of waste and its sewage discharge is currently considered an efficient and ecological method of waste treatment. This is how the European Union expresses itself in its CIUDAD 21 project, in which an efficient and sustainable city model is proposed. The domestic and industrial kitchen crusher has proven to be an appliance capable of transporting organic waste through the sanitation network, which reduces the carbon footprint, as CO2 emissions from collection trucks do not occur.
Regarding prohibitions and obligations, the Federation of municipalities and provinces recommends it. Some town halls have bans that date from old crushers, which carried blades. These blades made pieces, which clogged the drain network. The new ones (approved by CE) have a system of grinding by mobile wheels or rollers (depending on the case), which prevents there being pieces, and consequently, jamming.
They are forced in Andalusia in Health.
In some cases the system can be varied so that the crushed goes to a biogas digester and use its gas and biol as fertilizer.
It could also be used to facilitate composting. Although the residue can be excessively humid.
