How its made


The ‘How it’s made” video series informs viewers about recycling and how many materials are able to be reused and recycled to make other products, as opposed to throwing them away. The videos discuss how materials are disposed of in order to minimise waste and increase reusability. Generally, waste from existing products is sent to the manufacturer to reuse the material where they are able to combine it with new materials to produce new products.

Video 1 concentrates on the various ways corrugated cardboard can be used – focussing on its ability to be shaped and cut. (all manufacturing processes are very similar).

Video 2 and video 4 are interrelated and focus on packaging tubes and aluminium cans, respectively. The videos focus on the forming of cylinders and cylindrical products using aluminium sheeting. Alumiunium is lightweight, relatively cheap, and highly recyclable. Its flexability properties allow it to be formed easily and printed upon. The manufacturing processes are similar for the packaging tubes and cans, as they are both formed using rollers to press heat and ink the aluminium to produce the final products.

The third video about Tetrapak focuses on three main materials – plastic, foil and paperboard. The video discusses how these materials are utilised to make ‘leak-proof’ containers, which can be recycled, producing toilet paper and paper towels, etc.

Video 5 focuses on glass bottles and discusses the use of raw materials used, due to the copiousness and recyclability of them. Limestone and soda ash are said to be used in the process of recycling glass. Glass requires manufactured moulds and heat to manipulate it into desired shapes and therefore has a diverse manufacturing process as opposed to other materials.

Finally, plastic jars and bottles discussed in the video addresses the use of PET pellets and PET which has been recycled to produce shapes and products via the pellets being melted and injected into pre-formed, pressurised moulds. Only new plastic which is left over during the manufacturing process is used due to hygiene issues.

Recycling is an integral issue in the world today – it is important to know how things are made so that people know what can and cant be recycled (heightened awareness). Recycling is imperative if society wishes to preserve the environment and minimise waste in order to keep the earth clean.
