WASTE

Turning rubber and plastic waste into energy.

Introduction

RENEXUS in collaboration with our international partner have developed our scientifically tested and proven technology pyrolysis plant to recycle used rubber products and plastics into synthetic oil, gas and carbon black without causing the release of harmful toxic chemicals into the environment.

Our pyrolysis plant technology is based on low-temperature pyrolysis, a thermal decomposition of carbonaceous waste without oxygen in a closed cycle.

By using Al and machine learning via iOT data we can trace and track waste generating location thus we are able to identify the affected type of waste, the amount of waste generated and treated. 
 

Production and Consumption Waste
Reduction of waste volumes, their maximum processing and utilization is the main direction of the Russian state policy in the field of waste management. Disposal of used tires and other rubber products using pyrolysis plants is an effective way of waste disposal from both environmental and economic points of view.

Technology of Thermal Destruction of Carbon-Containing Waste Method-Dry Low Temperature Pyrolysis.
Dry low-temperature pyrolysis is the process of decomposition of organic compounds that do not get an access to oxygen. In the process of pyrolysis, a mixture of gases and other products is formed, the composition of which directly depends on the feedstock, pressure, residence time in the chamber, temperature regime, and heating time in the reactor.

Recycling rubber products through a pyrolysis technology allows in production of synthetic oil, carbon black, and steel cord. The accumulation of car tires has a negative impact on the environment. This type of waste does not decompose naturally does it requires a special method of disposal and recycling. Thus, pyrolysis is a promising method for processing a worn-out rubber which give a minimal impact on the environment and maximize financial benefit. 

The Pyrolysis Plant by RENEXUS could be used to recycle various types of rubber products and plastics such as: 

Rubber Products

Tires

Conveyer belt

All Type of Plastic

Polyethylene Terephthalate (PET)

Low-Density Polyethylene (LDPE)

High-Density Polyethylene (HDPE)

Polystyrene (PS)

Polyethylene high-density (PEHD)

Polypropylene (PP)

Polyvinyl Chloride (PVC)

Polycarbonate (PC)

 

PROCESSED MATERIAL AVERAGE OUTPUT (%)

TIRES & RUBBER PRODUCTS

DIFFERENT KIND OF PLASTIC

·30-50% synthetic pyrolysis fuel (oil)
·75-30% carbon black
·70-75% gas

  • Easy maintenance
  • Full recycling of loaded waste
  • No hazardous emissions
  • Self-produced resources of energy
  • Production of alternative energy resources from waste: synthetic pyrolysis oil, gas, thermal energy, carbon black

Description of The Pyrolysis Process

The plant operation is based on the method of pyrolysis process with no access of oxygen. It is equipped with the cylindrical retort which rotates around the longitudinal axis (rotary furnace principle. Retort is placed in a heat-insulated case and heated by the furnace gas coming from the heating base. Carbon incineration is steady due to the constant movement of raw material and carbon residual is being grind by help of metal cord. When heated, the plastic (rubber) polymers are decomposed and as gaseous enter the condensation line, where they are condensed and converted into liquid synthetic oil (own fuel for liquid fuel burners) and the excess gases which are used to heat the retort for the further pyrolysis process.

An effective heat exchanger accelerates decomposition of raw materials. The released pyrolysis gases are supplied for cooling and for further separation into fractions (asphalt, diesel, petrol). The pyrolysis cycle is finished after the end of the pyrolysis cycle, the reactor is cooled down, and carbon black is discharged and packed into big bags. (Metal cord is to be discharged in case of tires incineration).
