The first principle of green chemistry aims to achieve this:
Prevent Waste
If excess product is created, green chemistry suggests this instead of allowing it to become waste:
Reuse or repurpose it for another process
One limitation of the prevention of waste principle is that it requires this to accurately predict and minimize waste generation.
Precise planning and knowledge of chemical processes
Using this in a chemical reaction can prevent waste by speeding up the process and minimizing byproducts.
Catalysts
Prevention of waste seeks to reduce this environmental issue
Pollution
Green chemistry promotes this to reduce risks and prevent accidents in chemical processes that cause excess waste:
Safety
The prevention of waste principle may be limited in cases where this is unavoidable due to the nature of the reaction.
Byproduct formation
In green chemistry, replacing traditional solvents with this type can significantly reduce waste.
Water or supercritical CO2
The first principle of green chemistry specifically aims to reduce this type of waste:
Hazardous waste
To prevent waste, this chemical strategy focuses on using the correct/minimum amount of reactants and avoiding excess.
Stoichiometry
A challenge to implementing the prevention of waste principle is that it often requires these, which may not be available in all regions or industries.
Advanced technologies and resources
This process, used in the pharmaceutical industry, exemplifies waste prevention by employing enzymes to achieve high specificity and reduce side reactions.
