Description

“A system for manufacturing wood from mix plastic waste”
FIELD OF INVENTION:
The present invention generally relates to the conversion of mix plastic waste to a wood substitute, which can be utilized in the industry. In particular, the invention provides the system for manufacturing wood from mix plastic waste.
BACKGROUND OF INVENTION:
Plastic packaging (e.g. plastic bags, plastic packaging of ham, cheese, yoghurt, other foods and consumer products, and plastic utensils) and other plastic waste (bottle crates, garden furniture, buckets, plastic sledges, car bumpers, petrol cans, pipes, spools, computer shells, TV shells, plastic parts of fridges, etc.) are most problematic and the fastest- growing type of waste. According to common solutions, this type of waste is primarily landfilled, burned or used as filler. These solutions pollute the environment, are expensive and waste material that could be used as a raw material for new products.
Apart from that, everyone knows about plastic -waste recycling solutions where the waste is first sorted, then cleaned, and plastics of the same type are recycled into a uniform mass, granules or new products. The process of recycling is type-based, which means that, for example, LDPE (plastic packaging and bags), HDPE (plastic bags and thick-walled plastic products) or PET (plastic bottles of beverages) waste is washed, ground, dried and granulated. The plastics industry can use plastic granules made of one polymer as raw material for making new products. As sorting plastic waste by type is very expensive and time-consuming, mixed plastic waste that is not easy to sort and is usually not recycled; it is either incinerated or landfilled.
There is no suitable solution for recycling polymers of different types or Multi-Layered Polymers (MLP). Compared to other materials, such as glass or metals, plastic polymers need to be processed longer to be recycled. The biggest problem is that polymers of different types do not mix because their molecular weight differs and they have long polymer chains. Heating polymers is not enough to break down their molecules. So, to be recycled, polymers need to be identical to achieve effective mixing. If different types of plastic are melted together, they do not mix, like oil and water - they form layers.
The mixing and melting of different types of plastic results in a very unstable mass that is difficult to handle in a common plastics manufacturing process in order to achieve a stable process and product. To mix different types of plastic waste in reprocessing, other materials are added to the mixture.
Therefore, there is a need of a system for manufacturing wood from mix plastic waste to avoid shortcomings of conventional techniques.
PRIOR ART:
The patent document US20050051646A1 relates to a system and process for recycling plastic waste into a usable item. It provides a processing system which recycles all plastic waste and utilizes troublesome waste product in a productive manner. Accordingly, the present invention provides for a recycling system, including a first granulator for reducing plastic waste to a first particle size, and a second granulator for reducing plastic waste to a second particle size. The system also provides a frictional melting structure which melts said first particles and said second particles via use of a rotating plate. The present invention also provides for a process for recycling plastic waste, including the step of first granulating the plastic waste. Thereafter, the plastic waste is melted via a friction or rotating plate. The plastic is molded into a suitable form. The recycling system of the present invention can be used to manufacture numerous different products, for instance, but not limited to, vineyard posts, oyster posts, pipe supports, slats, spat trays, manhole covers, and railroad ties.
However, the said invention fails to provide suitable solution for recycling polymers of different types. The invention does not provide the system for manufacturing wood-like substitute from the mix plastic waste.
Another patent document WO2008066751A1 relates to systems for fabricating wood or natural fiber-plastic composite extrusions that employ recycled carpet waste as a component of the composite. The systems and methods can be used to process and combine recycled carpet waste with a fiber-polymer composite mixture to form a woodplastic composite with equivalent properties at reduced cost. The composite also includes unseparated processed carpet waste, which can be blended or dispersed within the fiber-polymer compound, resulting in a WPC of equivalent physical properties. Depending on the composition of the carpet used, the recycled carpet waste can include wool, nylon, polyester, polypropylene, jute, sisal, like materials, and combinations thereof. The composite may include additives such as colorants, lubricants, flame retardants, mold inhibitors, compatiblizers, coupling agents, other materials, and combinations thereof.
However, the weakness of such products is that the additives make these less weatherproof, and they are difficult to be nailed, milled or processed in any other way.
DISADVANTAGES OF PRIOR ART:
The existing prior art suffers from all or any of the following disadvantages :
• In the said prior arts, the plastic waste needs to be cleaned and different types of plastic wastes need to processed separately.
• Many of them fail to provide the suitable solution for recycling polymers of different types.
• Most of them fail to provide the fast and continuous process for manufacturing wood-substitute from plastic wastes.
• Conventional applications follow the plastic waste recycling solutions, where the waste is first sorted and plastics of the same type are recycled into a uniform mass, granules or new products. The mix plastic waste is not easy to sort and it is time-consuming.
• Many of them fail to provide weather-proof and water-proof end product.
• None of the prior art provides the system for manufacturing wood from mix plastic waste and thereby requires substantial amount of energy in the process and hence is time consuming as well as is not energy efficient.
Thus, there is an unmet urge to provide the invention that obviates the disadvantages of prior art and provides a solution to the problems yet unaddressed.
OBJECTS OF INVENTION:
The primary object of the present invention is to provide the system for manufacturing wood from mix plastic waste.
Another object of the present invention is to provide the system for manufacturing wood from mix plastic waste, which re-utilizes the mix plastic waste to prepare the wood product.
Yet another object of the present invention is to provide the system for manufacturing wood from mix plastic waste, which reduces the water pollution and air pollution (from landfilling) by reducing the need for conventional waste disposal and thus reduces greenhouse emissions.

Another object of the present invention is to provide the system for manufacturing wood from mix plastic waste, which produces the weather-proof and water-proof wood substitute.

There are heater zones, which semi-melts the densified material and by ejecting the barrel die hole, the material is cut into small densified lumps.
Step 3: Preparing compound
The semi-melted small densified lumps are then fed into the compounding assembly (3), where it is mixed with other additives, pigment, masterbatch, fillers/ Calcium powder, wood powder/ rice husk powder, chemicals and binders to prepare the compound.
Step 4: Grinding the mixture
The compounded material is the fed into the grinding assembly (4) to reduce the size.
Step 5: Molding the mixture in the final product using plastic planking assembly
The grinded material is fed into the plastic planking assembly (5). The assembly comprises of screw having different zones for mixing the high viscosity material. As the material exits the extruder, it is fed hot in directly into the molding-press. The cooling system attached to the mold with high compression force creates a solid product. The operating temperature of extruder is in the range of 170-180 degrees Celsius. Once the product is cooled, it is automatically ejected, as the mold opens with the hydraulic press.
