High Density Polyethylene Pipes with holes for segregating solid and liquid waste

New product as well as new enduse innovations in plastic industry would bring in expansions related to each manufacturing process, aiding manufacturers achieve a safety net for their business for a period of above 15-20 years. These manufacturers would have the flexibility of jumping from one end use to another end use which would lead to a multiplication of end users. These new product and new end use innovations would help in increasing the selling price of the final product which would lead to an increase of average selling price of the final product bringing in a higher net profitability and lower payback periods in comparison to existing business, without an investment on plant and machinery and also without much investment in marketing, as well as increase the product mix with an investment only in moulds and dies. New product and new end use innovations would make plastic rank as one of the top ranking material in agribusiness, building and construction, infrastructure and automotive end use sectors helping plastic increase the per capita consumption from a single digit to triple digit in the country.

An enduse innovation of High Density Polyethylene Pipes is to use them with holes for segregating solid & liquid waste.

• Waste is a material that no longer serves a purpose and so is thrown away. If not carefully disposed off, it will have an impact on the environment, whether it be unsightly litter in urban streets or contaminated air, soil, or water. But what is equally important about waste is that it is recyclable. For example, if all human, animal and solid wastes are recycled back to soil, than we do not need inorganic fertilisers to maintain the yield of crops.
• Today, India produces 180 mln tons of foodgrains and consumes 13 mln tons of inorganic fertilisers at a huge cost. Therefore, time has come when we have to look at the waste not merely as an environment polluter but recyclable material of great potential and energy saver.
• In India, we produce 300 to 400 gms of solid waste per person per day in tons of normal size. The figure is 500 to 800 gms per capita per day in cities in Delhi and Bombay. The problem in these cities is how to dispose large mass of solid waste daily.

Commonly practiced waste disposal/waste management processes in India include composting, bio methanation and incineration of Refuse Derived Fuel (RDF) pellets for power generation.

MSW Collection to Disposal Value Chain - Following steps :
• Source Storage & Segregation
• Collection & Transportation
• Dump Sites (Recyclable Materials Seperated)
• Waste Transportation
• Disposal in Landfills

Urban India produces about 42 million tons of municipal solid waste annually i.e. 1.15 lakh metric tons per day(Source :

High Density Polyethylene pipes would help in segregating soild and liquid waste wherein liquid waste would pour out of the holes and solid waste would remain as residue. Segregation of waste would thus become easier and less time consuming
• 1000 mm Dia PE pipe as per IS 14333 for sewerage application.
• The wall thickness of the pipe: 61 mm
• It weighs about: 175 kg / Mtr
• Drilled Holes of 12 mm
