DE4221070A1 - Recycling of waste plastics - to make boards, insulating materials, doors, etc. - Google Patents

Abstract

A recycling process is claimed in which waste plastics, pref. domestic and industrial waste materials contg. polyurethane foams and plastics, cable wastes contg. PVC and crosslinked polyethylene, rubber, laminated packaging films, hard PVC building materials, synthetic fibres and textiles, pref. together with waste wood prods., are converted to boards, insulating materials and other shaped prods., e.g. doors. No details of the process are given in the main claim. Dependent claims suggest that the waste materials are sorted, comminuted, mixed with a binder (esp. water-glass), and hot-pressed.

Description

Realization of the combi-plastic-wood-half-timber recycling Technology for the preferred series production of combi-recycling plates and molded parts, is made from the aforementioned combination All types of waste, preferably in mixed to similar types Plastic-wood batches and layers according to the latest Findings on the formulation of combi waste according to the TEREC CR technology applied.

In mixtures for the thermal pretreatments in the ZYKLO-THEXAR- Thermo process, the particle binding process for that begins PERSS process of TEREC technology. This includes the product properties formulated for the production of high quality TEREC-COMBI recycling products, preferably for building needs with special demands on quality and product requirements precisely specified electronically.

This results from the TEREC panel, door and molded parts manufacturing program, Product characteristics it so advantageous, not yet available worldwide.

In addition, there is a significant reduction in waste disposal and environmental effects through preferably forest resource savings for better protection of the world ecology.  

State of the art

Plastic waste, residual wood, wood waste from forestry as well as the wood industry and any semi-woods, if possible in Double use, develop, preferably from waste to be interpretive production fabric base of the future that they currently have, due to the lack of suitable recycling technologies, has not yet resulted.

Since these combi technologies do not yet exist and are currently separate recycling processes do not require supplementary combinations properties optimization of the above waste groups allow our environment to continue to grow through inhibition loose resource consumption damaged.

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

To a large extent, mixed plastic waste falls out of the house hold and those of the trade, PUR rigid and integral foam parts, thermoset waste from scrap vehicles and equipment, Cable waste with parts of PVC-w and PE-crosslinked, rubber, Multi-layer composite films, PVC hard waste from construction applications and synthetic fiber and textile waste, preferably for Waste deposits and landfills, in almost all branches of industry in large quantities, pure or mixed.

They should be combined with thin and waste wood and half timber granulated and so in our new combi recycling technology machined, processed into batches or layered, that from it solid panels, molded parts and any tight insulation fabrics are created.

Recycling is better than disposal. This gives the advantages of plastic preferably with wood and fibrous raw materials still improved, the variety of applications of plastic and wood waste, including semi-timber considerable, enlarged to optimized materials and thus the raw material base has also been expanded considerably.

This also eliminates the binder problems with harmful sub punching eliminated, since preferably on the self-binding effect of plastic combinations and or cellulose deposits the TEREC-ZYKLO-THEXAR-PROCEDURE into those to be connected Material structures are influenced accordingly technologically.

The mix variability of all the planned compos nenten or fractions to each other, the requirements for the pro product can be formulated in any way, 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 in production.  

The environmental and health protection effects are significant! This is especially true with regard to that, with the plastic original jump-making CFCs that contain the world wide forest area consumption, the urgently needed Decelerating the momentum of global climate destruction and the end Switching of poisonous substances preferably in the binders. In addition, this recurring recycling is increasingly helping to save petroleum resources and forest wood and thus protect the ecology.

Today, PU waste 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 open reactor with indirect heating approx. 600-1000 degrees C heated plastics are decomposed. The resulting expensive products in the form of gases and Oils are recycled.

The system also intends to use other disadvantageous methods Matic combustion of plastics as heating material.

All of the above Procedures that burden the Environment far more than full recycling of waste 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 than the products from full recycling than finished products and require considerably higher energy wall. This becomes market economy to the exclusion of the chemical and thermal recycling processes if they don't take new developments or be promoted nonsensically.

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

In addition, for the conservation of 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 nomical reasons.

The aim of the invention is:
the targeted recycling of the above-mentioned recyclable waste materials for the creation of new products, such as the waterproof, burglar-proof to fire-retardant TEREC RECYCLING DOORS from plastic and COMBI waste recycling, if possible in increasing series production, for fact recording in the Relieving the increasing landfill requirements with the resulting cost and environmental consequences of a supply of basic materials that secures valuable materials, preliminary and intermediate landfilling instead of towards the final landfill, for incorporation into recycling for the preferred manufacture of panels and doors from the TEREC plastic waste and COMBI RECYCLING.

Urgency:
Plastics are produced on a large scale today. For example, for each automobile, more than 140 kg of plastic are already being processed today. This proportion is growing continuously.

Only 1/8 of the total 1 to 2 million tonnes of plastic waste volume mens is 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, reuse should be a priority urgent task.

If it succeeds, most of the plastics will re not only become valuable resources, but also protects our environment.

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

The urgency is also confirmed in the fact that the meantime for the residual forest areas of the earth that are vital for human existence beaten further and 90% wet, mostly over long distances be transported. Approx. half of the transport timber weight cannot be used as moisture in the manufacturing process, transport-economically incomprehensible nonsense and ecologically a crime, that promotes the recycling products in this area too.

The forest wood is grated like carrots, for which one is natural tree, as a water reservoir with itself regulating evaporation and as an oxygen donor. 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 semi-woods 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 are created.

For the use of the plastic waste and their mechanical / physical dismantling as well as with the abge agreed 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 workable (nailing, screwing etc.) as well as in an endless form Exercise and surface design to far higher quality than state of the art, can be achieved.
