Abstract
Description
Die Realisierung der Combi-Kunststoff-Holz-Halbholz-Recycling- Technologie zur vorzugsweisen Serien-Herstellung von Combi-Recycling-Platten und -Formteilen, wird aus vorgenannten Comb- Abfällen aller Art, vorzugsweise in gemischten bis sortengleichen Kunststoff-Holz-Gemengen und -Schichtungen nach neusten Erkenntnissen zur Rezeptierung von Combi-Abfall nach der TEREC- CR-Technologie angewendet.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 Mischungen für die Thermo-Vorbehandlungen im ZYKLO-THEXAR- Thermo-Verfahren, beginnt der Partikel-Bindeprozeß für das PERSS-Verfahren der TEREC-Technologie. Dazu werden die Produkt-Eigenschaften rezeptiert zur Herstellung von hochwertigen TEREC-COMBI-Recycling-Produkten, vorzugsweise für den Baubedarf mit besonderen Ansprüchen an die Qualität und die Produkt-Erfordernisse präzise elektronisch vorgegeben.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.
Daraus resultieren aus dem TEREC-Platten-, -Türen- und -Formteile-Herstellungs-Programm, Produkt-Eigenschaften, die es so vorteilhaft, weltweit noch nicht gibt.This results from the TEREC panel, door and molded parts manufacturing program, Product characteristics it so advantageous, not yet available worldwide.
Zusätzlich erfolgt eine deutliche Minderung der Abfall-Deponierung und Umweltschutz-Wirkungen durch vorzugsweise Waldressourcen-Einsparungen zum besseren Schutz der Welt-Ökologie. 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.
Kunststoffabfall, Resthölzer, Holzabfall aus der Waldwirtschaft sowie der Holzindustrie und allfällige Halbhölzer, möglichst in Doppelnutzung, entwickeln sich, vorzugsweise aus Abfall zur be deutenden Produktions-Stoffbasis der Zukunft, die sie derzeit, mangels geeigneter Verwertungs-Technologien, noch nicht ergeben.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.
Da es diese Combi-Technologien noch nicht gibt und die derzei tigen getrennten Verwertungs-Verfahren keine Ergänzungs-Kombina tionen der Eigenschafts-Optimierung oben genannter Abfallgruppen zulassen, wird unsere Umwelt weiter zunehmend durch hemmungs losen Ressourcen-Verbrauch geschädigt.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.
Daher sollten jene, denen die Problematik der Schadensdynamik der Weltökologie hinreichend bekannt ist, engagierter handeln, um unseren Nachkommen ein sinnvolles Überleben zu ermöglichen!Therefore, those facing the problem of damage dynamics is well known to world ecology, act more committed, to enable our descendants to survive!
In großem Umfang fallen gemischte Kunststoffabfälle aus Haus halten und solcher des Handels, PUR-Hart- und Integralschaum teile, Duroplast-Abfälle aus Schrott-Fahrzeugen und -Geräten, Kabelabfällen mit Anteilen von PVC-w und PE-vernetzt, Kautschuk, Mehrschicht-Verbundfolien, PVC-Hartabfälle aus Bauanwendungen sowie Kunstfaser- und textile Abfälle, vorzugsweise für die Müllvorkommen und Deponien, in fast allen Industriezweigen in großen Mengen, rein oder gemischt an.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.
Sie sollen mit Dünn- sowie Abfallhölzern und Halbholz kombiniert in unserer neuen Combi-Recycling-Technologie so granuliert und zerspant, zu Gemengen verarbeitet, bzw. geschichtet werden, daß daraus feste Platten, Formteile und beliebig dichte Dämm stoffe entstehen.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.
Besser als die Entsorgung, ist die Wiederverwertung im Recycling. Dadurch werden die Vorteile von Kunststoff vorzugsweise mit holz- und faserigen Rohstoffen noch verbessert, die Anwendungs-Vielfalt von Kunststoff- und Holzabfall unter Einbeziehung von Halbhölzern beträchtlich, zu optimierten Werkstoffen vergrößert und damit auch die Rohstoffbasis erheblich erweitert.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.
Dabei werden auch die Bindemittel-Probleme mit schädigenden Sub stanzen eliminiert, da vorzugsweise auf die Selbstbindewirkung von Kunststoff-Kombinationen und oder Zellulosevorkommen durch das TEREC-ZYKLO-THEXAR-VERFAHREN in die einander zu verbindenden Materialstrukturen entsprechend technologisch eingewirkt wird.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.
Dabei ist die Mischungs-Variierbarkeit aller vorgesehenen Kompo nenten bzw. Fraktionen zueinander, den Anforderungen an das Pro dukt entsprechend rezeptiert beliebig, von 1% bis 99% gestaltbar.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%.
So wird beispielsweise die TEREC-CR-Spanplatte, mit durch Kunst stoff verstärkten Deckschichten, wie auch die TEREC-CR-Kunststoff- COMBI-Platte mit Span- und oder Faser-Verstärkern zur Festigkeits- Optimierung in zur Herstellung gelangen. 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.
Die Umwelt- und Gesundheits-Schutzwirkungen sind dabei bedeutend! Dies gilt besonders im Hinblick auf die, bei der Kunststoff-Ur sprungsherstellung anfallenden FCKW′s, die Eindämmung des welt weiten Waldflächen-Verbrauches, die damit dringend erforderliche Abbremsung der Eigendynamik der Welt-Klimazerstörung und die Aus schaltung von Giftsubstanzen vorzugsweise in den Bindemitteln. Außerdem verhilft dieses immer wiederkehrende Recycling zunehmend zur Erdöl-Ressourcen- und Waldholz-Einsparung und schützt damit die Ökologie.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.
Vorzugsweise PU-Abfälle werden heute über chemische Verfahren, z. B. durch Hydrolysen, auf ihre ursprünglichen Ausgangsstoffe Polyethen und Amine bzw. Isocyanate und andere Einzelsubstanzen zurückgeführt.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.
Andere Verfahren werden in Demonstrationsanlagen für die Pyrolyse von Kunststoffabfällen in Wirbelschichtungen angewendet. Hierbei werden die Kunststoffabfälle in ihre chemischen Bauteile zerlegt.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.
Die dabei in geschlossenem Reaktor mit indirekter Beheizung auf ca. 600-1000 Grad C erwärmten Kunststoffe werden zersetzt. Die daraus entstehenden teuren Produkte in Form von Gasen und Ölen werden einer Wiederverwertung zugeführt.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.
Andere unvorteilhafte Verfahren beabsichtigen sogar die syste matische Verbrennung der Kunststoffe als Heizmaterial.The system also intends to use other disadvantageous methods Matic combustion of plastics as heating material.
Alle diese o. g. Verfahren, belasten in unzumutbarem Maße die Umwelt weit mehr, als die volle stoffliche Abfall-Verwertung des zu schützenden Verfahrens. Die aus den belastenden Verfahren resultierenden Vorprodukte, wie Öle oder Aromate, sind um Viel faches teurer als die Produkte aus der vollstofflichen Verwertung als Fertig-Erzeugnisse und bedingen erheblich höheren Energieauf wand. Dies wird marktwirtschaftlich zum Ausschluß der chemischen und thermischen Recycling-Verfahren führen, wenn diese nicht neue Entwicklungen nehmen oder unsinnig befördert werden.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.
Dagegen vergammeln Abfälle der Waldwirtschaft in zunehmendem Umfang. Der weltweite Waldraubbau zwingt durch die Veränderung des Klimas der Welt, zum Anbau von schnell wachsenden, minder wertigen Dünnhölzern mit zweifelhaftem Wert für Ökologie und die Ökonomie.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.
Zusätzlich werden für den Erhalt der Waldressourcen der Welt, als Holzersatz-Rohstoffe sinnvoller nutzbare, alljährig nach wachsende Halbholzpotentiale, nur teil- oder fehlgenutzt bzw. verrotten außerhalb des biologischen Kreislaufes, der aus öko nomischen Gründen nicht erreichbar ist.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.
Ziel der Erfindung ist:
die gezielte Verwertung vorgenannter recyclingfähiger Abfall
stoffe für die Schaffung neuer Produkte, wie die wasserfesten,
einbruchsicheren bis feuerhemmenden TEREC-RECYCLING-TÜREN aus
dem Kunststoff- und COMBI-Abfall-Recycling, möglichst in zu
nehmender Serien-Herstellung, zur Fakten-Erfassung in der Entla
stung des steigenden Deponiebedarfes mit den daraus gegebenen

stoff-Versorgung, Vor- und Zwischendeponierung statt hin zur
Enddeponie, zur Einbringung in das Recycling für die vorzugsweise
Herstellung von Platten und Türen aus dem TEREC-Kunststoff
abfall- und COMBI-RECYCLING zu bewirken.
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.
Dringlichkeit:
Kunststoffe werden heute in großem Umfang produziert. Beispiels
weise pro Automobil, kommen heute schon mehr als 140 kg Kunst
stoff zur Verarbeitung. Dieser Anteil wächst ständig.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.
Nur 1/8 des insgesamt 1 bis 2 Mio.t Jahres-Kunststoff-Abfallvolu mens wird in der BRD einer Wiederverwertung zugeführt. Hierbei handelt es sich vorzugsweise um Thermoplaste. Die Vielzahl der weiteren Kunststoffe wird bisher nur entsorgt oder in Massendepo nien abgelegt. Zur Schonung des knapper werdenden Deponievolumens und zur Ressourcenschonung, sollte die Wiederverwendung eine vor dringliche Aufgabe sein.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.
Wenn es gelingt, den größten Teil der Kunststoffe einer Wieder verwendung zuzuführen, werden nicht nur wertvolle Ressourcen, sondern auch unsere Umwelt geschont.If it succeeds, most of the plastics will re not only become valuable resources, but also protects our environment.
Wegen der langen Entwicklungszeit betriebsreifer Verfahren und der ständig steigenden Verwendung von Kunststoffen, müssen sofort Maßnahmen ergriffen werden, die auch die bisherige Umwelt- Orientierung in der Spanplatten-Herstellung ändert.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.
Die Dringlichkeit wird auch darin bestätigt, daß die inzwischen für die Menschheit überlebenswichtigen Restwaldflächen der Erde weiter geschlagen und zu 90% naß, meist über weite Strecken transportiert werden. Ca. die Hälfte des Transport-Holz-Gewichtes ist als Feuchtigkeit herstellungstechnisch nicht verwertbar, transport-ökonomisch unfaßbarer Unsinn und ökologisch ein Frevel, der die Recycling-Produkte auch in diesem Thema fördert.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.
Das Waldholz wird wie Karotten zerrieben, wofür man der natür lichen Umgebung den Baum, als Wasserspeicher mit seiner selbst regelnden Verdunstung und als Sauerstoff-Spender, entzogen hat. Im Spanplattenwerk wird diese Speichernässe mit hohem, unnützem Heizenergie-Aufwand und mit umweltbelastenden Verbrennungsab gasen, bis auf 3% Restfeuchte aus dem Holz herausgetrocknet.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.
Dagegen erhalten wir trockene Kunststoffe und Halbhölzer sowie Abfallholz, als fast trockene Werkstoffe für unsere industrielle Fertigung. So kann mit unserer Kunststoff- und Combi-Recycling- Technologie zur Herstellung von besseren Baustoffen für die welt weite Anwendung, ein höherwertiger Ersatzbaustoff für weit offene Märkte geschaffen werden.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.
Für die Verwendung der anfangs genannten Kunststoff-Abfälle und deren mechanisch/physikalischen Zerlegbarkeit sowie mit den abge stimmten Mischkomponenten der variablen Beimengung von Halbholz- und Holz-Abfällen, wird das Combi-Recycling eine neue zukunfts weisende Produktpalette schaffen, die sich vorzugsweise in Bau platten aller Kategorien, Verkleidungen und Türen mit Zargen- Bausatz in anwendungsbedingten Verdichtungs-Zuständen, von soft bis hochfest, hart und in beliebigen Zwischenstufen, leicht bearbeitbar (nageln, verschrauben etc.) sowie in endloser Formge bung und Oberflächen-Gestaltung zu weitaus höherer Qualität als derzeit Stand der Technik, erreichen läßt.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.
