Abstract

1. The Saharawi refugees camp During the 1975 people living in Western Sahara, after the Marocco’s occupation, began to leave their cities, and settling in the hinterland of Tindouf in Algeria. Since 1979 more of 250.000 people live in a refugees camp, under very bad conditions, struggling to survive in this inhospitable part of the Sahara Desert, and organizing camps structure like a real city. So, from 30 years people settled on the camp are living only thank to humanitarian aids, arriving from world communities. 1.1 The waste in the refugees camp The consumption of food only from humanitarian aids cause the generation of a lot of solid waste (especially food packing) that create environmental impact and health risks. It was estimated the production of 1,5 kg/dia per capita of solid waste, constituted of the about 90% of packing: plastic, paper, cardboard, rubber, wood, textile and ferrous and not ferrous material. Figure 1 Saharawi refugees camp 2. Appropriate Technologies for plastic recycling Among all packaging the plastic have a really environmental impact and represents a very big consumption of non-renewable natural resources. Plastic represent about the 20% of total waste in Saharawi’s camp. The creation of simple process for plastic recycling can help to reduce the environmental impacts. Considering the contest, the process used for the recycling and manufacturing must implement appropriate technologies, that are the most appropriate and adapted to the environmental, cultural, economic and social contest where they are applied. Simple machines like a little shredder to size reduction, injection moulding machine or film moulding machine to plastic manufacturing, can be used for the recycling. The products derived from recycling and manufacturing can be used to the creation of artisan products (like, bags, hats, toys and others). It can be allow the realization of “recycling laboratory” in the camp. 3. Energy balance of plastic recycling Focus on the environmental impact, it was conduced a comparison, developed with the Life Cycle Assessment (Simapro6), between the recycling of 1 kg of PET and its collection and discharge in landfill. It was considered a simple recycling process characterized on the use of a little shredder and a plastic injection moulding machine.
