Discarded Assorted Waste & Plastics,which consists of wastes primarily from used cars,tires,plastics,households,Municipal Solid Waste, Construction & manufacturing Industry. The present methods of extraction,re-cycling,segregation,shredding, incineration, land filling or disposal into the ocean bed are costly, inadequate, inefficient,time consuming,cause leaching of plasticizers and stabilizers, are non environment friendly in both the Organized Sector & unorganized Sector after treatment or/& detoxification.
Process of treating and re-utilizing assorted Wastes and Plastics offers a 100% solution ie 100% reutilization for indoor & outdoor (external) applications or utilization of toxic gases, toxic metals, hazardous & toxic substances, Polychlorinated Biphenyls (PCB's), acids and polymers/plastics. These chemical substances, if not treated properly, are highly dangerous and hazardous to humans, plants and animals that greatly disturb the flora and fauna of the environment.
Various practices for Assorted Waste & Plastics disposal including but not limited to landfilling, incineration, soaking in open acid baths, magnetic separation and extraction,re- cycling, segregation,shredding are known. However, these procedures are not without pollutants such as obnoxious gas or greenhouse gas (GHG) emissions, emission of carcinogens or teratogens and leaching of chemicals into the soil and ground water. Also, these procedures are unsafe, time consuming, costly, requiring large amount of energy consumption and specifically need special machinery or skilled workers.
Efforts are being made for recycling Assorted Waste & Plastics or some parts for utilization in various value added applications. For example,Electricity can be produced by burning "municipal solid waste" (MSW) as a fuel. MSW power plants, also called waste to energy (WTE) plants, are designed to dispose of MSW and to produce electricity as a byproduct of the incinerator operation. MSW is managed by a combination of disposal in landfill sites, recycling, and incineration. MSW incinerators often produce electricity in WTE plants (Source:" The US Environmental Protection Agency/ EPA).
Waste-To-Energy application can take Refuse Derived Fuels (RDF) from municipal solid waste, Tire Derived Fuel (TDF) from used tires, and Landfill Methane Gas (LFG) to provide electricity generation. Thus,Integrated Gasification Combine Cycle (IGCC) produces Electricity from MSW & Tyres but also degrades the Environment with highly toxic emissions.
Also,Hot Temperature Plasma Processing of Waste has been carried out by Scientific Research Department of Polytechnic University of Puerto Rico & involves Gasification Process and Magmavication/Vitrification processes.MSW is also processed for Soil Improvement and Dust Control.
However, the methods or processes available in the prior art require heat or chemical treatment of wastes to make them suitable and sustainable raw material in building construction & for generation of energy/ electricity. Also, these methods normally include steps of extraction, re-cycling,heating, shredding, segregation or disposing that are inefficient, costly, time consuming,cause GHG emissions and are non-environment friendly.
A simple, more efficient, non-polluting, environment friendly, expeditious process and apparatus for bulk Assorted Waste & Plastics treatment for sustainable environmental reutilization of Assorted Waste & Plastics is needed.
Constituents of Assorted Waste & Plastics (AWP)
Many of the Assorted Waste & Plastics (AWP) are of Recyclable material or/& are reconditioned. Few of these are detailed here (refer to Table 1 for details). 1. End-of-life vehicles (Old automobiles & tires).
2. Inert waste: Construction and Demolition (C&D) waste, dirt, rocks, debris. Tsunami & Earthquake generated rubble.
3. Municipal Solid Wastes (MSD), Composite wastes, Commercial, Institutional wastes & Wastes collected from Offices & households:yard wastes, containers & product
packaging, and other miscellaneous inorganic wastes from residential, commercial and industrial sources (Examples: appliances, newspapers,boxes, disposable tableware, office and classroom, wood pallets, paper, boards, glass, bottles, cans, metals, waste clothing/ textiles, Tetra Packs,laminates, Hard & Soft PVC, polyethylene bags/parts, waste plastics such as bags, toys,empty boxes,containers,miscellaneous combustible & non combustibles items, Old furnishings, Films, sheets,coverings & laminations,Fibers,Carpets, Sand,Grit,all casings, enclosures,foils of plastic/metals, Scrap metals/white Goods,
Metal,wood, packaging, Fines, Ceramics,Gaskets etc). 4. AWP consist collectively of the damaged,discarded,old,empty, used,obsolete & outdated in design,scraps/ rejects from manufacturing process, historical wastes, orphaned products,end of life or discarded products,empty bottles/containers,covers, attachments,parts,substances from various sources made of different materials.

In the Process of TRAWP invention,there is minimum or nil Pretreatment. AWP may be washed/ cleaned if covered by other substances/oil but it is not a necessity. The above mentioned AWP constituents are Fully and Directly reutilized/ reused as a raw material in manufacturing & construction activity ( minor or major) in a direct manner or after minimum processing, effort, expense,effort or time spent.
The AWP is re-used (sometimes after dismantling or cutting it for size reduction) encasing it in a suitable container/ enclosure made of Metallic/Ceramic/ Concrete/Plastic / baked clay/composites or similar material of appropriate shape & size, the remaining space is than filled with a liquid filler material having binding properties, which hardens after sometime once it cures/hardens. This liquid filler material having binding properties will have Chemical &
Physical (post curing) properties which are same or similar to the different types of AWP material (s) used.

NOTE:
(]) Transition metals are: scandium, vanadium, manganese, cobalt, copper, yttrium, niobium, hafnium, tungsten, titanium, chromium, iron, nickel, zinc, zirconium, molybdenum, tantalum, rhenium. (2) Stabilisation processes change the dangerousness of the constituents in the waste and thus transform hazardous waste into non-hazardous waste. Solidification processes only change the physical state of the waste by using additives, (e.g. liquid into solid) without
changing the chemical properties of the waste.
(4) A waste is considered as partly stabilised if after the stabilisation process dangerous constituents which have not been changed
completely into non-dangerous constituents could be released into the environment in short, middle or long term.
The above mentioned Plastics are:
A. Recyclable Plastics (Thermoplastics): PET etc.
B. Non-Recyclable Plastics (Thermoset & others): Multilayer & Laminated Plastics, PUF, Bakelite, Polycarbonate, Melamine, Nylon etc.
HIGH-DENSITY polyethylene plastic (HDPE),used to make milk, water jugs & shampoo containers
LOW-DENSITY polyethylene (LDPE), used to package cream cheese, butter,spreads, plastic bags & other dairy products.
TYPES OF USES & APPLICATIONS OF TRAWP
Almost all of the above are
1. In Manufacturing for mostly Internal use/applications: LOW DENSITY AWP (Plastics,tires)
2. In Construction for mostly External use/applications: HIGH DENSITY AWP (Building,Metal parts,C&D wastes).
