Waste recovery and sustainable development

 

 

Currently, household waste management is a universal problem that affects everyone on the planet. 90% of the waste burned or dumped in landfills is in low-income countries.

 

This failure to manage waste has serious consequences such as ocean contamination, obstruction of drainage channels and flooding, disease, respiratory problems due to the burning of garbage in the open air, and the death of animals.

Low-income countries collect about 48 per cent of garbage in cities and only 26 per cent in rural areas, and recycle only 4 per cent of the waste.

 

In the Ivory Coast, 3,000,000 tons of waste produced each year throughout the country, for a current management capacity of 1,250,000 household waste over seven years. All this waste from households and small businesses is often piled up or scattered in the streets and at least without prior selective sorting.

Progress in waste recovery and innovative waste management are needed for these populations

 

The recovery of waste through recycling, composting and energy transformation would offer enormous opportunities for rural populations, particularly in the context of their agricultural production and in energy production (electricity, heating, cooking, etc.).

There are several solutions to overcome this problem, including the introduction of selective waste sorting. In addition, compost from organic waste could be used as a fertilizer to replace chemical fertilizers. Compost could also allow the production of digestate, biogas which in turn could be transformed into heat, electricity or fuel.

The recycling of plastic waste in pavement could be the answer to the problems posed by unpracticable roads.

 

All these initiatives require the involvement of different actors, in particular the public authorities (supervision of the sector and improvement of operating conditions), the private sector (technical and financial support), civil society (training, capacity building and awareness-raising), scientists (carrying out socio-anthropological, socio-technical and technological studies, etc.), and of course the populations themselves to facilitate the implementation of innovation models within the communities.
