Resource recovery and waste-to-energy: framing a feasibility study

Overview

A resource recovery study should begin with the available material, its variability and the existing collection and disposal system. Record quantity, composition, moisture and contamination evidence and identify how representative the sampling is. A single assumed yield cannot establish project feasibility.

Compare recovery pathways using consistent boundaries for material inputs, energy, residues, emissions, transport and operating costs. Identify market and disposal requirements for outputs and by-products. Include seasonal variability, feedstock agreements, maintenance needs and the risks of inconsistent input quality.

Document the source of every yield and cost assumption and test sensitivity to uncertain inputs. A planning calculator can explore scenarios but cannot guarantee production or financial return. Define the additional sampling, pilot trials and engineering review needed before procurement or investment decisions.

Construct a mass balance with an explicit system boundary. Account for incoming material, recovered outputs, residues and any stock change over the reporting period. Describe the sampling method and the confidence in composition assumptions. If several feedstocks are blended, retain the quantities and characteristics of each input so that a change in material quality can be traced to an operating or feasibility assumption.

For scenario comparison, use a common basis for capacity, operating time, maintenance, transport and output handling. Review how the result changes with feedstock availability, contamination, energy use and output acceptance. Keep preliminary vendor estimates distinct from measured pilot results. A attractive headline production figure can conceal restrictions in the assumed feedstock or operating window.

The feasibility report should identify missing evidence and the next decision gate. That may include further sampling, pilot trials, an output-market review or a project-specific engineering study. Assign an owner and acceptance requirement for each action. Do not turn a planning estimate into a claimed carbon benefit or verified financial outcome without the relevant boundary, factors and review evidence.

Key considerations

• Define the operating question and asset boundary.
• Record input quality, units, ownership and revision.
• Agree review responsibilities and acceptance criteria.
• Verify project-specific requirements before implementation.
