The Team should prepare a focus area flow chart for each of the selected focus areas as follows see Worksheet 13:
- List the different steps of the focus area and draw a box around each step
- List the most important inputs (resources) for each step on the left, such as energy (electricity, fuels), water, raw materials and chemicals
- List the most important outputs for each step on the right, such as solid wastes, heat, emissions, noise and wastewater
- List the intermediate and final products between the steps, such as clinker and cement
Add any information on units of measurement for inputs and outputs and quantities and costs that is already available. Otherwise this information can be gathered as part of the next tasks.
The focus area flow chart will look differently for a department or process step (e.g. kiln, boiler house) compared to specific energy uses (e.g. steam system, motors, fans). See Company examples for examples of flow charts of focus areas for companies that participated in the GERIAP project.
