About the project Edit

Manufacturing paving stones from salvaged plastic bags mixed with sand. The technique is inexpensive. Plastic waste is melted in a container. The dense paste is passed through a mould to make paving stones. The same plastic waste is used as a combustible which reduces the production investment considerably.


In what ways is this project unique and creative? Edit

Making paving stones from plastic waste gives value by turning waste into a resource. From noise, pollution and environmentally unfriendliness to a source of profit.

What is the social value of this project? Edit

Apart from the dangers of the toxic gas generated from the melted plastic, this form of recycling improves the environment and, therefore, public health. On another level, it creates jobs and profit.

What is the potential of this project to expand and develop? Edit

After Mopti, large-scale production was envisioned by a ceramic plant specializing in tile production and other floor-coverings used in the building. Simplification is in progress, particularly domestic use.

What was the triggering factor of this project? Edit

Finding a solution to the issue in Mopti. Plastic bags can in the long run create an air-tight barrier in the earth thereby preventing absorption of rain water and lowering groundwater levels which could dry up (linked to global warming).

What is the business model of this project? Edit

This project could be productive in many way if we agreed on the fact that it is inevitable that plastic bags are used in business. Take into account its lifetime.
