Plastics are made from non-renewable resources such as oil, gas and coal. By recycling plastic this conserves these natural resources, diverts non-biodegradable waste from landfill and enables the production of new plastic products.

Rigid plastics are those molded into hard shapes such as tubs, water tanks and bumper bars. Rigid plastic waste is generally post-industrial plastic such as factory defects or product that are broken or worn down. By recycling unwanted plastic this can reduce the reliance on landfill waste disposal, which can be costly and environmentally detrimental as plastics are not biodegradable. Plastic polymers are made from oil, coal and gas so by recycling unwanted scraps into other useful products this reduces the need for primary extraction and helps conserves these important non-renewable resources. It is estimated that 1.8 tonnes of oil are saved for every tonne of recycled polyethylene produced. Depending on the plastic type, scraps may be recycled into a range of product including plastic films, carrier bags, sheets, bottles, household products and more.
Australia recycles large amounts of plastic every year and there are numerous plastic recyclers operating who will accept rigid plastics for recycling. This may be offered as a pick-up or drop-off service. Plastic scrap bins may also be provided for collection of scraps on site.
What Happens When It's Recycled?
Rigid plastics such as water tanks are collected and may be pressure cleaned for reuse. Otherwise they shredded into smaller more manageable pieces which are washed to remove contaminants and melted down. New stabilisers and colourants may be added, depending on what the final product will be. This material is then chopped into pellets and ready for reuse in new plastic manufacturing.
