The separate collection of municipal solid waste is, at the moment, the only real alternative to landfills for which we have been accustomed for decades. Differentiating Plastics, metals and glass to start them for recycling is definitely the wisest choice, but how do you adjust for the moist fraction of the waste? Recent studies have shown that even for the simple collection of waste, special requirements are needed, especially with regard to the bestowal and the bags used. Those biodegradable plastic , in fact, in the vast majority of cases are not compostable.
If they were introduced in the Composter, where the organic fraction should be given, they would cause a slowdown of the composting reaction, obtaining an end product of very poor quality. The solution was provided by Sumus
, a company of Carmignano di Brenta, in the province of Padua, which has experimented, patented and then made of recycled paper bags for the collection The damp, to be used in combination with a perforated basket . The bag, made of post-consumer recycled paper certified for composting, is equipped with a double bottom in cardboard, always recycled, which allows the organic waste to Tranbreath, losing by evaporation a good part of the liquids in it Content.
In this process, a great help is given by the perforated trash, which allows air circulation . Do you smell troublesome? Not even the shadow, thanks to the perspiration of rejection. By losing liquids, a little at a time, the organic fraction dries, becomes lighter and decreases even in volume, and the bag, albeit smaller, has an average volume of two litres more than what would contain a bag in Bioplastics. In this way the rejection is also easier to process, once given in the composter. Moreover, to kick off a composting reaction, it is necessary to add to the waste also a fraction consisting of twigs, flakes and everything that is produced by pruning works. Thanks to bags in recycled paper, all this is no longer necessary, because this role is played by the bags themselves, which contribute to generate good quality compost.
