Recycling Service

Our country is short of recycling plants. Existed enterprises work in two or three shifts but still are not successful. Plastic recycling is done as by large plants so and by small firms. The main difficulty is not recycling but waste collecting and sorting. Society of the Plastics Industry (SPI) introduced special codes to simplify classification process of various plastics. You see them having a look at the bottom of the plastic bottle and the number inside the triangle identifies the type of plastic.

In case, there is marking it will be easy to identify the plastic, but how can we recognize it when there is no marking and you need to recognize what the plastic made of? So that you can recognize which plastic you are dealing with, you need a bit of practical experience. It is rather simple: you should analyze physical-mechanical features of the plastic (solidity, smoothness, elasticity etc) in contact with flame. It may sound strange but different kinds of plastic burn differently. For example: some may blaze up brightly and burn down intensively (without soot), some in the contrary strongly soot. Plastic can even make different sounds while burning! That’s why it is very important to identifiy the type of plastic according to its indirect indicators.

HDPE- High density polyethylene has blue, yellow tipped flame, burns slowly, plastic drips. Smells like candle wax (paraffin), very soft and oily has no soot, density 0,91-0,92 g\cm3 LDPE- Law density polyethylene more firm and dense than HDPE, fragile. Burns like HDPE, density 0,94-0,95 g\cm3

PP Polypropylene. Burning PP has blue, yellow tipped flame, like HDPE, with sweet odor, plastic drips. Melted PP is transparent, cooled dawn plastic gets muddy, becomes firmer than HDPE, smoke smells like burnt rubber, sealing wax.

Polyethylene Terephthalate (PET) Strong, firm and light material. Density is 1, 36 g\cm3. It is heatproof between -40 +200 degrees temperatures. PET is resistant to dilute acids, oil, spirits, inorganic salts and most of organic compounds. Burns slowly with smoky flame.

Polystyrene (PS) PS plastic strips can be easily bended, but sharply breaks with typical crackle, it has strong yellow, flame and sweet flowery odor. It is well dissolved in organic solvents like sterol, acetone and benzene.

Polyvinyl chloride (PVC) expansible, fire-resistant, has strong smoke while burning and very sharp smoke odor. Density 1,38-1,45 g/ cm3

Plastic recycling is very advantageous business, as the result of recycling (PP, PVC, PE granules etc) is very popular among manufacturers of equipment and engineering materials. Nowadays more widespread business is recycling of plastic bottles, film, big-bags and other.

To organize waste recycling business it is necessary to get the license and eco finding. Area 200 m3 is also required, besides area there should be special equipment, as made in Russia so and in foreign countries.

Recycling business technology consists of three stages:

Crushing

Washing and drying

Agglomeration or granulation

First stage – is crushing of plastic waste into small particles 10-30 mm

Second stage is washing and drying of crushed polymers, it is one of the most important stages, as quality of washed material depends on the quality of final product.

The process of washing and drying is as follows: Initial ground flakes (a) are ingested from a shredder by prewashing unit (1) where passing on gauzy cylinders of the aggregates precleaning of contamination is carried out, thus pollution is allocated in the tank for the contaminations (2) on the bottom of the aggregate. According to degree of contamination cleaner can be added into the 1 section of the tank (4). Then material is forced delivered to the washing unit (3), where it is subjected to intensive washing. Further, by means of activator (c) and through piping (d) the material is fed to geared motor separators after that to the intensive cleaning (e) turbulent separators where water is removed, following which, being forced through outlet pipe(f), washed and cleaned material comes to the drying unit (5). While going through turbulent gravitational separators (g) it is subjected to active drying up, after that clean and dry material is fed to the collection hopper of the extruder, sintering machine or through discharge cyclone (6) to the big bag

The next stage is agglomeration is gathering small plastic particles into a mass . Chunk can be sold as ready raw material or it can be granulated.

The aim of granulation process is getting of more homogeneous, more pure material. Granulated material is more expensive than chunk.

At an initial stage of organizing your own business you should decide what and how much you will recycle. It will help you to find the best equipment.

Nazarov Systems company is a well known, reliable manufacturer of plastic recycling equipment. We are specialized in manufacturing of high-grade washing complexes intended for washing and drying of strongly contaminated grinded (including wastes from proposal area) wastes of any kind of thermoplastic waste: PP big-bag, film, HDPE, LDPE, PС, PVC etc..

The equipment is certificated, it has no analogues and efficiently functions in 26 regions of Russian Federation and in CIS countries. All parts of the equipment are manufactured of stainless steel..

Manufactured equipment is based on three groups of patented inventions by Vadim Nazarov. He has great experience in recycling and knows the problem with plastic waste.

Equipment is compatible with all kind of crushing machines, extruders and agglomerators. The complex functions in an automatic mode, which is easily operated, requires low energy and water consumption.
