Conditions and Processing.
fig.17 Plate chopper.
Financing is minimal, investments return in 6-12 months if there’s no stealing by sorter people. An area of 300 square meters is established and guarded. The surface of the area is asphalt or concrete. Sorting tables are mounted with covers protecting from sun and rainfalls.
Equipment used: (chopper) shredder for wood and leaves, press compactor, metallic container (barrel, 200m3) for artisanal remelting of polymers, forms of metal profile for casting of polymer-sand stuff.
What about dirty bags and packaging? A civilized way is using “Nazarov” system – recycling of plastics of any contamination level into “flakes” stuff for sale.
Less civilized way is to melt them in a big barrel till they get a consistency of sour cream. After that we add some dry sand, mix it, so it becomes like dough. Then it comes to metallic forms to create road tiles. It’s desirable to press it to obtain maximum durability. Hand and electric power tools are used for splitting combined waste (shoes, domestic appliances). All unsorted polymers go into the barrel to get melt till a liquid condition. Sand and dyestuff are added to get a consistency needed. Then it goes to forms. Heating device is made of bunch of mirrors to focus the sunlight to heat the energy source.

On fig.18 there’s a road leading to a sorting area, the place of temporary storage of SMR, HW, HCW.
