Elements and Performance Criteria

1. Acquire required data
   • Identify system to be analysed.
   • Define appropriate boundaries for this system.
   • Identify relevant data which is available for the system and its subsystems.
   • Identify required data which is not currently available.
   • Negotiate with relevant stakeholders to obtain data which is not currently available.
   • Acquire necessary and appropriate data.
2. Calculate resource efficiency/loss
   • Undertake mass/energy balance over system.
   • Identify subsystems making greatest contributions to loss by mass/energy balances over selected subsystems.
   • Calculate sustainability impact of identified losses.
   • Calculate mass/energy efficiencies of system and analysed subsystems.
3. Prepare recommendations
   • Investigate subsystems responsible for significant loss.
   • Determine currently available responses.
   • Determine required longer term responses.
   • Draft recommended responses in appropriate form.
4. Communicate with relevant stakeholders
   • Identify relevant stakeholders.
   • Determine stakeholder information needs and wants.
   • Analyse data which may be appropriate to communicate with stakeholders.
   • Prepare and disseminate information to stakeholders, as appropriate.
   • Negotiate solutions with stakeholders, as required.
5. Communicate required responses as appropriate
   • Identify what communications are required and to whom.
   • Prepare appropriate reports and recommendations.
   • Pitch reports and recommendations, as appropriate.
   • Brief appropriate persons as required by determined responses.
   • Finalise appropriate recording.

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Sustainability incorporates all of	survival of the ecology/physical environment (to manage the impact of the business to ensure the survival of the physical environment) economic viability (efficiency, cost and waste reduction and competitiveness to support survival of the business) social sustainability (to manage the impact of the business to ensure its continued survival within the community and the survival of the community).
Mass/energy balancing includes one or more of	mass balancing is an analysis technique which allows for the calculation of mass flows and consumption through a process and losses of mass from the system/product energy balancing is an analysis technique which allows for the calculation of energy flows and consumption through a process and the losses of energy from the system/product mass and energy balancing may be undertaken as separate activities or in some circumstances as a combined mass/energy balance.
Appropriate response when impact cannot be prevented includes one or more of	capture and storage (e.g. scrubbing) and similar ‘end of pipe’ solutions dilution/dispersion and similar techniques which reduce concentration but not amount other approaches which meet the sustainability requirements.

identify appropriate responses

communicate the above as appropriate.

---

Knowledge Evidence

Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to determine process loss through mass or energy balancing including knowledge of:

process and changes which occur at each step in selected value chain

principles of sustainability

root cause analysis

relevant legislation, regulation and protocols, government incentives and other initiatives

first law of thermodynamics

defining boundaries for systems subject to mass/energy balancing

required data, sources of data from process, and use of data proxies, where necessary

mass balancing techniques

energy balancing techniques, including the use of tables of thermodynamic properties (steam tables), and the use of specific heat capacity and specific latent heat
