The Team now needs to decide which possible options to investigate for feasibility. The easiest way to do the screening of options is by putting them in one of these categories:
- Options that can be implemented directly. They are technically simple and need little or no money to implement. For example, repairing leaks, changing an operating procedure, reducing excess air from the boiler.
- Options that require further analysis. These options are technically more complex or require a financial investment. For example, replacing a compressor, recovering heat from boiler blow-down, or replacing lime with alternative materials in cement production.
- Options that can be considered at a later stage. These options are probably difficult to investigate and implement, for example, because the costs are too high, they take too much time to investigate, or a plant upgrade is planned that will cover this option already.
The meeting with management under task 1a should also give you an indication of what screening criteria to apply!
Worksheet 15 can be used to categorize options, and look under Company examples to see what other companies have done.
Options that require further analysis will be investigated for their technical, financial and environmental feasibility as part of step 4. Options that can be implemented directly do not require a feasibility analysis, however, the technical, financial and environmental details will still need to be recorded.
