Generating electric energy from organic and plastic waste

This method will be the leading technology applied in clean energy resources. Its practicality is clear: while clean energy is being produced, the stockpile of continuously increasing organic waste which causes harmful emission is being reduced. The resources can easily be gleaned from nearby landfills.

Introduction

The usage of plastic waste is a new turn in the field of producing renewable energy; new and „clean” energy can be gained.

The inventor/producer of the power plant and our company are both devoted to offering the highest level technology in the field of renewable energy usage, especially in the field of thermo-catalytic technology.

A new solution had to be worked out, because of the increasing amount of organic waste and the continuously changing laws. Consequently, the present situation obviously shows that there is an increasing need of our thermo-catalytic waste processing system.

One of the leading waste recycling technologies of our partner company is thermo-catalytic. It is possible to process waste in an anaerobic environment, unlike waste incinerators. In the thermo-catalytic process plastic waste goes through a hermetically closed system, therefore no harmful gases will be emitted.

By using this technology the difficulties regarding the continuous problems generated by the disposal of plastic waste will disappear.

The thermo-catalytic system designed by the inventor/producer was created in a way that the whole process, from input to output, is performed automatically without any problems, therefore the possibility of shutdowns can be reduced to a minimum.

The process can be easily monitored and controlled with the help of an electronic controlling device, which plans and controls the previously given heat parameters in each phase. Naturally, a hi-tech automatic safety stopping mechanism was also developed for the plant.

This technology serves two purposes: it helps dispose organic waste that has been appearing in large amounts all over the world and creates „clean” and cheap electric energy via the waste utilizing unit in order to supply the nearby communities with electricity.

The present waste situation:

At present waste management is a serious problem in most of Europe and in Hungary as well. Due to the development of societies and technologies, the amount of municipal waste is increasing per capita. Therefore the legislators of the EU must put more emphasis than ever on controlling waste disposal and on keeping deadlines in each member state. A number of regulations and deadlines have been made in order to abolish anachronistic landfills and to control the amount of waste held in modern landfills but when speaking in the long term, landfills cannot serve as a solution.

On the one hand with the present amount of waste they will get filled up very fast. On the other hand municipal waste contains a lot of recyclable materials such as: paper, glass, metal, and a large amount of plastic based organic materials.

With the recycling of paper, glass and metal waste we have an easy job, because there is already a sufficient solution existing. In the case of plastic and other waste the situation is not as simple.

Plastic waste gets to the landfills where its degradation will only begin after decades, causing earth pollution and air contamination, thus polluting the environment and poisoning animals, water, land and air. It is thus obvious that placing municipal waste in landfills does not offer a long-term solution. Waste management will have to be reconsidered, the amount of waste will have to be reduced, and the selection of recyclable waste will have to be emphasized. Instead of the incineration of organic waste with slow degradation, new disposal technologies must be developed.

This is where our partner company offers leading technology.

A number of concepts have been developed in order to solve this problem mainly related to energetic usage. Most of them prefer incineration that cannot be carried out because of the objections of local inhabitants. Among present market solutions the anaerobic heat degradation technology, namely thermo-catalytic technology will be the solution.

The power plant

Plastic and rubber are special types of waste which are actually indestructible. Getting rid of these materials by incineration is not the right solution since it pollutes the environment, especially by free carbon particles (dense smoke) and the toxic materials connected to them. Rubber waste has been utilized in the form of ground rubber or by incineration in cement factories until now. The production of rubber and plastic is basically a polymerization chemical technology. By turning back the process using external energy, the material with large molecules will fall apart to materials with smaller molecules. The briefly described depolymerization process, when maintained by adding heat to it, is considered thermo-catalytic process, when the reaction area is located in anaerobic atmosphere.

A part of plastic waste can be recycled, but there are some that cannot be recycled due to their production process or for other reasons (polluted, etc). In such cases the same process can be applied as described in case of rubber. Plastic is basically a crude oil derivative, but with less carbon content. Because of this, the rate of paraffin derivatives produced will be higher.

By the thermo-catalytic processing of rubber and plastic the following products will arise:

  •     oil
  •     gas
  •     soot/slag
  •     steel waste (only in case of tires).

Oil may be utilized in internal combustion engines by which generators can be driven. Therefore, they will be able to produce electric energy. Not to mention, it is possible to make use of the heat energy as well, for example for heating, if needed.

The complex thermo-catalytic system + the block producing electric energy require relatively small space. It can be easily placed in an ordinary landfill in the most convenient way to accommodate the technological process.
