Chemistry for the environmentThis book highlights the crucial role of chemistry in the fight against plastic pollution, presenting innovative scientific solutions for transforming waste into sustainable resources. Major contributions- Congolese researcher Nicolas Eliot Mondjo has developed a chemical process to convert plastic waste into gas and tar. This innovation illustrates the efficient valorization of waste. Chemical strategies addressed- Biodegradable plastics: made from plant materials (starch, cellulose), they decompose rapidly.- Chemical recycling: decomposition of plastics into reusable monomers, even in the event of contamination.- Degradation catalysts: substances that accelerate the transformation of plastics into fuels or raw materials.- Neutralization of microplastics: adsorption and filtration techniques to remove invisible particles from soil and water. Limits and challenges- Complexity of processes- High costs- Need for political and educational supportThe book invites us to consider chemistry as a powerful ecological and environmental lever.
