What are by-products?
Have a commercial value can be sold.
Can be reused/ recycled within the chemical processes in which they are produced.
Can be used to generate energy for the chemical plant.
Can be used in another chemical process.
What are Waste material?
Have no commercial value.
Cannot be reused/ recycle within the chemical process in which they are produced.
Cannot be used in any other chemical process.
Cannot be used to produce energy for a chemical process.
What do operating costs consist of?
Cost of raw material, Staff and salaries, maintenance of equipment, generating high pressures, generating high temperatures transport of materials.
How to lower energy consumption
Recycle heat - Heat produced in exothermic reactions is transferred to a material (such as water) that stores the energy and transports it to another part of the manufacturing plant where it can be used to produce electricity.
Operating continuously - Operating reactors constantly saves energy and costs associated with heating the equipment to the appropriate temperature each day.
