Disposable materials are article of daily use that are usually brought to Recycling.
Recycling includes the reprocessing materials like used packings (made of glass, plastic, aluminium, tinplate, composed material)  into "secondary raw materials".
Recycling reduces the consumption of fresh raw materials and energy. Expecially the virgin production of aluminium consumes huge quantities of electricity.

1. No-cost disposable materials (packings)
Packings are high quality containers for safe storage and attractive presentation of food, cosmetics, medicine and other articles of daily use.
Some of these containers can be reused as no-cost materials for science experimentation (El-Marsafy).
These materials are available new at many places ([email protected]).
