2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate sheeting in a greenhouse. The second largest consumer of polycarbonates is the construction industry, e.g. for domelights, flat or curved glazing, roofing sheets and sound walls. Polycarbonates are used to create materials used in buildings that must be durable but light.

4. Greenhouse - Wikipedia

   en.wikipedia.org/wiki/Greenhouse

   The terms greenhouse, glasshouse, and hothouse are often used interchangeably to refer to buildings used for cultivating plants. The specific term used depends on the material and heating system used in the building. Nowadays, greenhouses are more commonly constructed with a variety of materials, such as wood and polyethylene plastic. [2]

5. Biodegradable plastic - Wikipedia

   When OPEC halted oil exports to the US to boost global oil prices in 1973, [10] more plastic and chemical companies began making significant investment in the biosynthesis of sustainable plastics. As a result, Imperial Chemical Industries (ICI UK) successfully produced PHB at a yield of 70% using the strain Alcaligenes latus . [ 9 ]

6. Plastic recycling - Wikipedia

   en.wikipedia.org/wiki/Plastic_recycling

   Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfills, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions.

7. Low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Low-density_polyethylene

   Production of these trace gases from virgin plastics increases with surface area and with time, so that LDPE emits greenhouse gases at a more unsustainable rate than other plastics. In a test at the end of 212 days' incubation, emissions recorded were 5.8 nmol g −1 d −1 of methane, 14.5 nmol g −1 d −1 of ethylene, 3.9 nmol g −1 d −1 ...
