Environmental & Product Stewardship

 

The environmental performance of Richdale Plastics regarding air emissions, water and energy consumption, scrap/waste production during all the stages of the manufacturing of the PE film process, is supported by the improvement objectives set by Richdale Plastics environmental strategy.

Raw Materials

All LDPE, LLDPE and HDPE polyethylene prime polymers are food grade and consist of non-toxic molecules made up of only carbon and hydrogen atoms.

Film Manufacture

Our PE film is extruded by a clean and simple method without the use of process chemicals and without the need for coatings. All waste film generated during manufacture is collected and recycled as part of the production process. There are no by-products of manufacture during this low energy process.

The production of polyethylene into PE film is safe and energy efficient and the product is easily and cleanly handled. All polyethylene raw materials used by Richdale Plastics production comply with the Food Contact regulations of Australia and New Zealand.

Information regarding compliance with other world standards is available on request.

Film Use

Extruded PE films contain no toxic substances and Richdale Plastics PE films comply with the Australian regulations for polyethylene packaging PE films in food contact applications. Polyethylene is a low density, high-yielding material that is very ecologically efficient as a PE film material – more than other commonly used packaging substrates

Transparent and opaque PE films demonstrate excellent use of the Earth’s resources. They have effective moisture barrier properties, achieved without coatings. The PE mono and co-extrusion film process also provides superb sealing characteristics to produce secure packs and good shelf life, avoiding product waste.

Continuous PE film extrusion improvements have contributed to a reduction in the weight of film used in packaging applications by delivering lightweight films down to 15 microns. Development of our new co-extruded PE films has also allowed reduction of package weights without compromising marketing appeal.

PE Film Scrap derived from the manufacturing process

Richdale Plastics has always been involved in specific activities to optimize its production processes with the aim to reduce and rationalize the use of raw materials. These activities have positively impacted on the reduction of scrap and the possibility to reuse them. A high attention to the product quality does allow the recovery in-house of all the production scrap and subsequent regeneration.

Any scrap left is recycled by specialised companies. Richdale Plastics use this valuable secondary raw material into other non-critical PE film applications.

Packaging covenant

The Australian Packaging Covenant aims to minimise the environmental impacts of packaging by focusing on sustainable design, recovery and recycling, and product stewardship.

Richdale Plastics can provide assistance, resources and the know-how to ensure our customers  meet their packaging covenant commitments in an effective and proactive manner by carrying out a feasibility study of their plastic waste stream going back to industry through plastic recycling and saving the resource rather than going to landfill.

Richdale Plastics can establish an annual review with our customers to ensure the Packaging Covenant requirements are kept up to date.

Disposing of PE Film

Most of our extruded PE films are not biodegradable: unless stated. When used in landfill sites, plastic waste has the positive benefit of stabilising the ground without producing unpleasant or harmful by-products

When incinerated efficiently, only carbon dioxide and water vapour are produced with no pollution. The resulting energy released as heat is twice that of coal. PE film, whether transparent, white or coloured can also be cleaned, recycled and reprocessed by Richdale Plastics into other non-critical PE film applications.
