As a process supervisor for Biogas plant, you selected food wastes from large kitchens and restaurants as a substrate and not from protein Residues from Pharmaceutical Industry because the former is Much Cleaner With more energy content Less expensive Less money is spent on transportation

As a process supervisor for a Biogas plant, choosing food wastes from large kitchens and restaurants over protein residues from the Pharmaceutical Industry can be attributed to several reasons:

1. Much Cleaner: Food waste from kitchens and restaurants is generally cleaner than protein residues from the Pharmaceutical Industry. This means it requires less processing and treatment before it can be used as a substrate in a biogas plant.

2. With more energy content: Food waste typically has a higher energy content compared to protein residues. This means that it can produce more biogas per unit of waste, making it a more efficient choice.

3. Less expensive: Food waste from kitchens and restaurants is often less expensive to obtain than protein residues from the Pharmaceutical Industry. This can significantly reduce the operating costs of the biogas plant.

4. Less money is spent on transportation: Depending on the location of the biogas plant, it may be cheaper to transport food waste from local kitchens and restaurants than to transport protein residues from the Pharmaceutical Industry. This can also contribute to lower operating costs.
