In the case of traditional waste-management technologies, different types of plastics have to be sorted and selected, separated and cleaned prior to recycling.  One of the advantages of the SYLROCK-technology is that any type of plastic can be processed, even mixed plastic types, and no cleaning or selection is necessary. This is an application never used before.


After processing, the converted material:


§   shrinks to  ¼  of its original size

§   loses its moisture content

§   all unmelted materials  get wrapped in polyethylene and polypropylene

 Recycling mixed plastic waste is a crucial issue nowadays.

Recycling contaminated mixed garbage – up until the creation of SYLROCK -- was neither economical nor profitable. Traditionally, the more complex and contaminated the garbage to be recycled, the more expensive the preparation phases.  This especially applies to the plastic content of dirty household waste containing consumer goods’ packaging, even if it derives from garbage collected separately for recycling.   SYLROCK is changing all that!  

Another issue that encumbers treatment or elimination of household waste is that plastic components  (mainly plastic foils, foams, bags and bottles) are not biologically degradable, and  – due to their shape and small specific weight – they increase the volume of  waste and can easily get carried away by the wind. Thus, eliminating these plastic waste elements and decreasing their volume is a great achievement in and of itself, but also making useful and valuable products out of them, by which natural  materials (such as wood) can be replaced, is an extraordinary benefit to SYLROCK_.   

 The objective of SYLROCK  is to recycle disposed plastic waste and

a) produce valuable materials suitable for further processing;

b) protect the environment by creating new products, which can be used as high-quality construction materials, replacing materials such as wood, concrete, brick, etc.

c) eliminate big-volume, low-specific-weight components of waste.


After processing waste using the SYLROCK method, a homogenous material is created, which is the basic (matrix) material. When other additives are added to this material, it becomes a blended compound material. 


Nowadays, even by applying selective waste-collection practices, only approximately 15% of  household and industrial plastic waste is gathered for recycling. Of that 15%, only the cleanest, most valuable part is actually recycled, the rest is piled up and disposed to landfills, increasing environmental encumbrances. 


Due to the lack of sufficiently advanced technologies, treating the remaining 85% and recycling the plastic content within has not been feasible, due to financial reasons.  In the case of traditional methods, to-be-recycled plastic materials are separated and then cut. Cutting requires a significant amount of energy, but it implies a lot of technological issues, as well.   Foils can slip among cutting knives and even the smallest piece of metal can ruin the blades or even the whole machine. Ropes and cords can get tangled among rotating parts and shafts. Therefore, cutting is a procedure to be avoided in case of processing contaminated, heterogeneous mixed plastics. 


The next step of the traditional method of recycling is homogenization of the pre-heated plastic, using aggregates as well, and afterwards, the material is formed by an extruder or molding tool.

These procedures may, in fact, shrink plastic waste to a certain extent, however, producing a useful product, replacing natural materials, is not possible. 


The SYLROCK-method is a new solution, accomplishing waste-management objectives efficiently at a significantly lower cost.
