Kitchen Waste Shredder: Hui or pfui?
There is controversy about kitchen waste shredders: Are they banned or allowed in the EU? Do they pollute or clean the sewage?
Well bravo: Brussels even tells us what we have to put into our sinks. The argument often falls when talking about kitchen waste shredders. To correct one thing: no, they are not generally prohibited in the EU. They are covered by the Waste Water Ordinance - and national or regional regulations apply. In Ireland, Norway, Sweden, Denmark, Spain and Italy crushers are allowed, in the UK they are even subsidized by municipalities. In Germany and Switzerland, the approval is with the local authorities and is usually not granted. Crushing equipment, which ensures that garbage, paper and other items in the drainage systems, contradict the purity requirements for wastewater in many places. If you want to purchase a kitchen waste shredder, you should first check with the authorities.
The pros and cons of Kitchen Waste Crushers
Waste Shredders are installed below the sink between the flushing drain and the siphon and are about 20 by 15 centimeters in size. They use an electric centrifuge to chop up the organic food scraps, such as peas or vegetable peelings, while running water, and then channel them into the sewage system. In the digesters of wastewater treatment plants, these biowaste can be converted into sewage gas. So far so good. From the point of view of their advocates, the miners save the waste separation and the biotones. And even more.
Hygienic, environmentally friendly - or burdensome?
Organic kitchen waste often gets into the sewage system via the toilet flushes anyway. However, they are crushed in the sewage treatment plants with much less effort to process than the coarser garbage from Klospülungen or Biotonnen. Speaking of bio-waste: the waste volume and the disposal costs associated with this type of waste separation could be minimized with kitchen waste shredders. In addition, they offer a hygienic advantage. Particularly allergic people like to keep bio garbage cans full of bacteria.
Authorities on the ground have the last word
Critics argue that crushed biobase in sewage could overload sewer systems. However, such observations can not be confirmed from the US - and there have about 50 percent of all households a kitchen waste shredder. Another counter-argument is the possible overloading of sewage treatment plants by additional organic waste. Furthermore, increased deposits could intensify the maintenance of the sewer systems, which are designed especially for rainwater and used drinking water. Last but not least, the drinking water consumption increases because the shredders work with running water. So is a kitchen waste shredder useful? It would be nice if everyone could decide for themselves, instead of the official.
