Description

State of the art

Plastic waste, residual wood, wood waste from forestry as well as the timber industry and any semi-timber, if possible in Double use, develop, preferably from waste to be interpretive production fabric base of the future that they currently, in the absence of suitable full recycling technologies, not yet represent worldwide.

Since these COMBI technologies do not yet exist and the waste ends in current recycling processes, mostly in the CO ₂ generation, pyrolysis or costly and energy-consuming hydrogenations, without the possible additional combinations of the property optimization mentioned above To enable waste groups, our environment is increasingly further damaged by unrestrained wood resource consumption.

Therefore, those facing the problem of damage dynamics is well known to world ecology, act more committed, to enable our descendants to survive!

Mixed plastic waste is thrown out of the household on a large scale and those of the trade, PUR hard and integral foam parts, Thermoset waste from scrap vehicles and devices, cable waste cases with parts of PVC-w and PE-crosslinked, rubber, more layered composite films, PVC hard waste from construction applications as well Synthetic fiber and textile waste, preferably for waste disposal and landfill, in almost all branches of industry in large Quantities, for recycling in 2 main groups as Duro and Ther mo-plastics mixed.

They should be combined with thin and waste wood and half timber granulated in the new TEREC-COMBI recycling technology machined, processed into batches, or layered that preferably solid sheets, molded parts and any density Insulation materials are created as high-quality building products.

Recycling in TEREC-COMBI recycling is better than disposal incineration or distillation, instead of the avoidably expensive heating and CO ₂ pollution. Through this process, the advantages of plastic, preferably with woody and fibrous raw materials, are further improved, the variety of applications in the use of plastic and wood waste, including semi-timber, is considerably expanded as optimized materials and, as a new second raw material base, enables considerable resource protection .

This also eliminates the binder problems of the damaging sub punching eliminated, since preferably on the self-binding effect of plastic combinations and or cellulose deposits in the woody material structures influenced accordingly technologically becomes.

The mixture variability of all intended components or Fractions to each other, can ent in product requirements can be formulated appropriately, arbitrarily, from 1% to 99%. For example, the TEREC-CR chipboard is made with art reinforced cover layers, as well as the TEREC-CR plastic COMBI board with chip and or fiber reinforcement for strength Optimization to manufacture.  

The environmental and health protection effects are significant!

This is especially true with regard to that of the plastic original jump manufacturing CFCs that contain the world wide forest area consumption, the urgently needed Decelerating the momentum of global climate destruction and the end switching of toxic substances, preferably in the binders of normal chipboard. In addition, this helps recurring Recycling increasingly to save petroleum resources and forest wood and thus protects the ecology.

PU waste today is preferably processed using chemical processes, e.g. B. by hydrolysis, to their original starting materials Polyethene and amines or isocyanates and other individual substances returned.

Other processes are used in demonstration plants for pyrolysis of plastic waste applied in fluidized beds. Here the plastic waste is broken down into its chemical components.

The thereby in closed reactor, lossy with indirect Heating to about 600-1000 degrees C will be heated plastics decomposes. The resulting expensive products in the form of Gases and oils are inefficient recycling. The system also intends to use other disadvantageous methods Matic combustion of plastics as heating material.

All of these above. Procedures, burden the order to an unreasonable degree world. The full recycling of waste has the opposite effect of the process to be protected. Those from the stressful procedures resulting preliminary products, such as oils or aromatics, are by a lot times more expensive and require considerably more energy than Products from the full material TEREC-CR waste processing. In the market economy, this would have to exclude the chemical and thermal recycling processes if they are not new ent Take development paths or be stressful, nonsensically promoted.

In contrast, forestry waste is increasingly decaying Scope. Global forest grubbing is forcing through change the world's climate, for growing fast growing, less quality thin woods with dubious value for ecology and Economy.

In addition, to conserve the world's forest resources, usable as wood substitute raw materials, useful every year growing half-timber potentials, only partially or incorrectly used or rot outside the biological cycle that comes from eco is not achievable for nominal reasons.

The aim of the invention is:
the increasing- utilization of the aforementioned recyclable waste materials for the creation of new products, such as the waterproof, burglar-proof to fire-retardant TEREC-RRECYCLING-DOORS, -Plates, -formed parts, -finished building, -tile, and-roofing elements and without energy carrier construction in TEREC plastic and COMBI waste recycling, if possible in increasing series production.

This enables the facts of the consequences of a value to be recorded basic material capture for cost-effective ver evaluation in your own industry. It is in contrast to the end Landfilling and storage, the resulting costs for waste International transports up to expensive chemical or pyrotechnic recycling, as basic material wrong ways.  

This confirms the sensible economy by itself benefits of introducing such waste raw materials into the TEREC-CR technology for the preferred production of -Plates, doors and molded parts from TEREC plastic waste- Refinement and the TEREC-COMBI-RECYCLING manufacturing system.

These are preferred in large waste generation centers stationary and for widely separated waste deposits as preferably mobile TEREC-GS waste processing and CR recycling tion systems for cost-effective collection of valuable materials.

urgency

Plastics are produced on a large scale today. Example wise per automobile, there are already more than 140 kg of art fabric for processing. This proportion is constantly growing worldwide.

Only 1/4 of the total 1 million tonnes of plastic waste volume is being recycled in Germany. Here it is preferably thermoplastics. The multitude of other plastics have so far only been disposed of or in bulk storage never filed. To protect the increasingly scarce landfill volume and to conserve resources, should be reused in your own Country must be a priority.

If it succeeds most of the plastics this again not only become valuable resources, but also protects our environment. Add to that the waste in the TEREC-CR products with a long-term application deposit long durability (at least 50 years) and the TEREC-CR-Ver drive can then be fed again.

Since the beginning of this century, the forest areas of the earth have been around 60% have been reduced. The resulting loss of oxygen contributes significantly to the fact that the pollution in the Air can no longer be managed. With further negative development this interaction exists for higher levels of life, foreseeable no more survival on this earth.

Because of the long development time, operationally mature processes and the ever increasing use of plastics, must immediately Measures are taken that include the previous environmental orien tation in chipboard production changes.

The urgency is also confirmed in the fact that the meantime residual forest areas that are vital to human survival the earth, hit further and 90% wet, mostly over a long distance Routes are transported. Approx. half of the transport timber Weight is as moisture, not technically ver valuable, transport-economically incomprehensible nonsense and ecologically Outrage that promotes recycling products in this area too.

Forest binds water and wind! Disregarding these principles will the forest wood was grated like carrots, for which one usually has no opening Forest replacement, the tree's natural environment as water store with its self-regulating evaporation and as acid has withdrawn fabric producer. Often the branch remains in at least 1/3 amount of wood, for rotting and pest feeding back without disposal.  

In the chipboard plant, this storage wetness with high, useless Heating energy expenditure and with environmentally harmful combustion gas, dried to 3% residual moisture from the wood.

In contrast, we get dry plastics and half-timber as well Waste wood, as almost dry materials for our industrial Production. So with our plastic and COMBI recycling Technology to produce better building materials for the world wide application, a higher quality replacement building material for wide open Markets created and the earth's last forest saved.

For the use of the plastic waste and their mechanical / physical dismantling as well as with the abge mixed components of the variable admixture of half-timber and wood waste, COMBI recycling will be a new future create pioneering product range, which is preferably under construction panels of all categories, cladding and doors with frame Kit in application-related compression states, from soft to high strength, hard and in any intermediate level, light editable (nailing, screwing etc.) as well as in an endless form Exercise and surface design to much higher quality than can currently achieve the state of chipboard technology.

Contrary to the usual stationary arrangement of such Techniques of securing and recycling raw materials, claimed the TEREC-GSM and the TEREC-CRM system also preferably on mobile amphibious foundations arranged TEREC-Technik-Tech techniques in order to utilize usable ones that are not currently meaningful Refine waste potential and in the TEREC COMBI recycling Involve the cycle.

This is based on the economic principle that the recovery Technology more cost-effective for the recurring raw materials comes as vice versa and thus burdensome transports, costs, The majority of energy and harmful effects are eliminated.
