Paper cup recycling in Russia: blockchain precept – RECYCLING journal

Paper cups are comprised of virgin bleached pulp. It is a worthwhile materials for recyclers. The plastic insert – polyethylene – can be eliminated and recycled, for instance, into tiles.

Why, then, are paper cups hardly recycled all around the world? The issue lies in separate assortment and accumulation of the required quantity of cups for processing. Since natural residues are within the cups, they can’t be saved for a very long time whereas ready for the mandatory quantity due to the fungus unfold. So used paper cups are now not appropriate for processing and may hurt costly gear.

Despite all these difficulties, there’s a plant in Russia that has tackled recycling paper cups. It is the Solnechnogorsk Experimental Mechanical Plant – SOEMZ. The founding father of the plant is Denis Kondratyev, professor of the Sustainable Development Faculty at Moscow Witte University. Denis can be a member of the Supervisory Board of Waste Paper Processors League Association, which unites 73 recycling crops and waste paper dealing with operators in Russia. Denis is presently implementing a decentralized assortment of waste paper for his plant.

SOEMZ manufactures merchandise from molded fibers: fruit trays, paper cup holders, transport packaging for greens, shampoos, deodorants, and so on. – greater than 140 sorts of merchandise. The plant merchandise repeatedly obtain worldwide awards: Red Dot Award, WorldStar Packaging Awards, PART Award. SOEMZ provides a variety of products to European nations. For instance, lodgements for mugs, salad bowls, and bra holders are provided to Germany. All of those merchandise embrace paper cups as recycled materials.

Molded fiber has all the time been comprised of newspapers. Still, lately the price of newspapers has elevated dramatically, and its amount has lowered attributable to a lower in demand for printed merchandise. The system of separate waste assortment is poorly developed in Russia. Because of that, there isn’t any assortment of newspapers from the family sector. For a while, the plant used an OCC grade of waste paper. OCC assortment charge is excessive in Russia (round 90 %), however the worth is comparatively excessive – about 25,000 rubles (275 Euro) per ton. The use of such supplies for the manufacturing of molded fiber will not be economically possible.

SOEMZ has been cooperating with IKEA for a number of years. ÄGGKOPP “Paper Wave” packaging for the transport of fragile goods won an international award at the 2019 Red Dot Award. SOEMZ recycles unpopular sorts of waste paper from IKEA, for instance, a transport nook and coreboard. IKEA additionally collects paper cups in its shops and delivers them to SOEMZ with different sorts of waste paper. SOEMZ put in a excessive focus pulper (16%). It simply separates fiber.

For two years, SOEMZ processed about 500,000 cups mixing used paper cups with different grades of waste paper, like a lot of the recycling amenities on this planet. But SOEMZ desires extra: the corporate plans to arrange a decentralized procurement of used paper cups in response to the blockchain precept. At the identical time, the plant intends to change fully to the processing of cups and abandon the acquisition of one other kind of waste paper. It is simpler for a plant to work with a single sort of materials since fixed gear adjustment will not be required.

In Russia, the corporate “Parmatech” produces gear engaged in dry fiber separation – an aerodynamic dispergator. The paper cups go into the dispergator, and the output is dry paper fiber and plastic movie, which can be recyclable. In the method of dispersion, a pointy stress drop happens. Acidophilic and different micro organism don’t survive in such situations, thus eliminating the opportunity of the looks and spreading of molds. As a consequence, after dispersion, the fiber may be saved considerably longer with out the chance of molds growth, which is unattainable with long-term storage of used paper cups. Such supplies may be saved and transported. It has the identical concept as powdered milk, powdered eggs or freeze-dried merchandise. Also, the dispegator copes with the duty of fiber separation higher than the pulper as a result of no water is used or contaminated within the course of.

SOEMZ may also implement the zero waste precept in apply. The plastic that is still after fiberizing will grow to be a homogeneous materials – polyethylene – with out inclusions of one other kind of plastic, guaranteeing its demand. SOEMZ will course of fiber into paper merchandise, and plastic recyclers will sort out plastic. In addition, the fabric from the cup supplies an obvious financial plus. This materials will not be topic to cost dangers; there isn’t any overstated demand for it.

It will not be worthwhile to centrally accumulate and retailer paper cups; decentralizing the gathering of uncooked supplies will remedy the issue. SOEMZ plans the set up of dispergators at waste paper collectors amenities that serve procuring facilities. It is the which means of a decentralized assortment system: totally different suppliers will set up dispergators on their amenities. The gear is cell, dispergator has an equal measurement to the ocean container. Each dispergator can produce roughly three tons of fiber per day. As a consequence, SOEMZ will buy the quantity of fiber required for manufacturing from paper cups – 20 tons per day.

The plant is presently negotiating the set up of dispegators with two waste paper collectors situated in Moscow and Nizhny Novgorod.
