  • the present invention relates to a multi-purpose module /container/ block from mixed waste plastic, plastic type resins and related polymer originated from any source including municipal solid waste.
  • the present invention further provides a method of converting such mixed waste plastic or polymer or recycled plastics or resins or combination thereof, into an environment friendly product useful for construction of roads, footpaths, etc.
  • the present invention provides rapid natural degradation of such mixed waste plastic in environmentally friendly manner.
  • Plastic waste is a growing concern and the drivers behind it look set to continue. Attempts made to decrease in plastic production or use is on, however, this is unlikely to be maintained.
  • Plastic is a highly useful material and its applications are expected to increase as more new products and plastics are developed to meet demands. As plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years (Jefferson Hopewell et al., Phil. Trans. R. Soc. B (2009) 364, 2115-2126). However, current levels of their usage and disposal generate several environmental problems.
  • Plastic Container Code System (PCCS) into seven classes that are being identified by markings on the bottles. These contain distribution of plastic as per their properties (Web Referencehttp://www. plasticseurope.org/information-centre/news/news- 2011/plastics-manufacturers-call-for-ban-on-landfill-in-europe.aspx).
  • the corresponding classes for recycled plastics are class 1 and class 2and in few of the cases these include classes 4, 5 and 6, as well but it gets sorted from the general mass collection of recycled material or separately collected, however such separate collection and sorting add to the cost of processing. It is important note that the mixtures of recycled plastics from more than one of the PCCS classes particularly materials from class 7 and from class 3 when mixed with material from other classes of material may lacking its utility due to its properties and hence routed to landfills due to non-uniformity in mixing with. Such materials have lacked an alternative use or manner of disposition cause of concern.
  • PET or Number 1 Plastics are plastics made up of Polyethylene Terephthalate and include water bottles, and containers for soft drinks, jam and butter jars. The plastics falling under this category of recycling codes are very tough and resistant to moisture. Curbside recycling programs often pick these up. Confirm that with your district's program coordinator today.
  • HDPE High Density Polyethylene
  • Number 2 Plastics plastics made up of High Density Polyethylene and include milk and juice bottles, shampoo bottles and water pipes. The plastics falling under this category of recycling codes are resistant to moisture and permeable to gas.
  • Plastics made up of Polyvinyl Chloride and include cling films, PVC pipes and certain juice bottles.
  • the plastics falling under this category of plastic recycling codes are easy to blend and well suited for tough conditions. These plastics are usually not recycled as it is usually very expensive to recycle with the current technology. Moreover, there may not be enough of such items to justify their recycling.
  • LDPE or Number 4 Plastics are plastics made up of Low Density Polyethylene and include frozen food bags, bread, shopping bags and tote bags. The plastics falling under this category of plastic recycling codes are easy to seal and fairly resistant to moisture. These plastics are usually not recycled as part of the curbside recycling programs.
  • PP or Number 5 Plastics are plastics made up of Polypropylene and include kitchenware, medicine bottles, diapers, straws and syrup bottles. The plastics falling under this category, are resistant to heat and chemicals, and offer good resistance to moisture.
  • PS or Number 6 Plastics are plastics made up of Polystyrene and include CD cases, disposable kitchenware, meat trays and egg cartons. Make sure to check with your curbside recycling program - some programs include these while others don't process these.
  • Plastics are plastics made up of Polycarbonate or Acrylonitrile butadiene styrene and include some water bottles, DVDs, nylon substances, baby milk bottles and various types of electronic casings. These are traditionally not recycled. -The waste plastic is mixture of all these and other contaminants of solid waste as well.
  • plastic waste is being produced in today's upgrade-and-dispose culture.
  • a key example of this is the mobile phones; its plastic components contain several toxic substances. Although these substances are not at levels to cause immediate risk, if quantities increase and end-of-life management is inadequate, such as the open burning often practiced in developing countries, there is potential for environmental pollution and human health impacts (Plastic Waste: Ecological and Human Health Impacts, EU Report 2011).
  • plastic waste by incineration is not environmentally friendly, which leads to carbon dioxide and other greenhouse gas emissions even though incineration can generate energy.
  • incineration of plastics still has some drawbacks, such as high capital and maintenance cost.
  • An alternative process to decompose plastic Waste to generate energy and useful gaseous products is gasification.
  • a conventional gasification process releases tars, heavy metals, halogens and alkaline compounds etc., and causes environmental problems.
  • Another effort to utilize plastic waste, which seems to be promising, is the pyrolysis of plastic waste, resulting in a mixture of hydrocarbons of heavy oils and olefins, however, cost, and quality of the product is still an issue.

  • the base material plastic waste is cleaned, depending on its solid contamination, after the possible primary cleaning step, the plastic waste is inputted into a recovering machine, where, due to the pressure in the recovering machine and the heat transmitted to the material, the waste becomes a largely melted mixture, the said largely melted mixture is transferred into a heated internal mixing machine where the material is intensively mixed while adding heat, and if required, the melted material is transferred into a making up machine where matrix material blocks or matrix material products are produced.
  • Indian patent application no. 4429/CHE/2012 teaches process of disposing harmful plastic and solid waste in hollow cement concrete products.
  • Said invention provides a process of disposing harmful plastic and solid waste in hollow cement concrete products. Such waste is segregated separately and heated to a temperature of 150 degrees centigrade. This heat converts it to liquid/semi-liquid state.
  • This liquefied plastic waste is injected into a concrete hollow block or similar storage units. A hole is provided in these concrete containers at an appropriate place for injecting the liquefied plastic waste. Once the hollow concrete product is fully filled with this plastic/paper waste semi-liquid, the hole provided is sealed with appropriate cement/glue, to make it air-tight. This ensures that the stored waste becomes chemically inactive.
  • Indian patent application no. 220/CHE/2003 teaches waste polymer-granite blend for block making. Waste plastics and aggregate mix having waste plastics up to 20 -30 parts by weight, and the aggregate 80-70 parts by weight is made into a hard block, choosing proper machinery.
