Ocean LDPE Sheet 300 Micron for Shivalik Solid Waste Management in Solan, Himachal Pradesh

Ocean Non Wovens supplied 20,000 sq m of Ocean LDPE Sheet 300 Micron to Shivalik Solid Waste Management Ltd in Solan, Himachal Pradesh. Shivalik Solid Waste Management runs the common hazardous waste treatment, storage and disposal facility (TSDF) at Majra, near Nalagarh, which serves industry across the state. This article looks at what 300 micron LDPE sheet does at a waste management site and where it fits alongside the heavier HDPE liners that such sites also need.

Waste handling in a wet hill district

Solan district includes the Baddi–Barotiwala–Nalagarh industrial belt, one of Himachal Pradesh’s main manufacturing areas, with a large pharmaceutical base. Industrial waste from units across the state is sent to the Majra facility, which in 2026 the state government described as the only authorised facility in Himachal Pradesh for collecting, treating and disposing of industrial hazardous waste.

Water is the main enemy on any waste site, and more so in the Shivalik foothills, where the south-west monsoon brings heavy rain. Rain that falls on open waste, stockpiles or treatment areas becomes contaminated runoff or leachate, which then has to be collected and treated. Every square metre kept dry is liquid the facility does not have to handle. Thin, flexible polyethylene sheet is one of the cheapest ways to do that.

What 300 micron LDPE sheet is

Ocean LDPE sheets are extruded from low-density polyethylene, with a density of roughly 0.910–0.940 g/cm³. 300 micron is 0.3 mm. At that thickness the sheet is light (about 0.28 kg per sq m, so 20,000 sq m weighs roughly 5.5 tonnes), soft enough to fold around corners and pipes, and quick to lay by hand.

LDPE is chemically inert, does not rot and resists water, dilute acids, alkalis and salts. It has lower tensile and tear strength than HDPE and lower resistance to some hydrocarbons and solvents.

Where LDPE sheet is typically used at a waste facility

A 300 micron LDPE sheet is not a primary landfill liner. Indian rules call for 1.5 mm HDPE (or equivalent) in the base liner of municipal solid waste landfills, and hazardous waste cells are lined to CPCB requirements with heavier HDPE systems. LDPE does the lighter jobs around them. At waste sites, sheet of this grade is typically used for:

• Rain covers. Temporary covers over active cells, stockpiles of waste or soil, and stabilised material waiting for disposal, to keep rain out during the monsoon.
• Interim cover. Covering parts of a cell that will not receive waste for some time, before final capping.
• Secondary and temporary barriers. Lining temporary storage areas, bunds and drains where the liquid is compatible with LDPE.
• Moisture barriers in buildings. Under floor slabs of sheds, stores and treatment buildings.

Before using LDPE in contact with any liquid, check its chemical resistance against that liquid. For leachate, solvents and hydrocarbons, HDPE is the safer choice.

Handling and installation notes

1. Prepare the surface. Remove sharp debris, stones and protruding objects. Thin sheet punctures easily on rough ground.
2. Lay loose. Unroll without stretching, so the sheet can settle as the material beneath it moves.
3. Hold it down. Use sandbags, tyres or soil-filled bags along edges and in a grid across the sheet. Wind uplift is the commonest cause of cover failure on exposed sites.
4. Join or overlap. Heat-weld panels where a sealed barrier is needed; for temporary rain covers, generous overlaps laid shingle-fashion downslope shed water.
5. Anchor edges in a shallow trench at the top of slopes.
6. Inspect after storms and patch tears before the next rain.

UV-stabilised sheet can be used outdoors, but thin sheet left in the sun for long periods will age faster than buried sheet.
