Method & Evidence

AimTo investigate the technical and economic feasibility of using high-chromium tannery sludge as feedstock for a biogas plant.
MethodLaboratory-scale anaerobic digestion and techno-economic analysis.
ProcedureTannery sludge was subjected to anaerobic digestion in a laboratory setting, adhering to Finnish SFS standards. The process was evaluated for its technical viability, and associated costs (transport, processing) and legislative aspects were considered.
ContextIndustrial waste management, specifically in the leather tanning industry.

Variables

Strengths & Limitations

Strengths

  • +Addresses a real-world industrial waste management problem.
  • +Combines technical and economic feasibility assessment.

Limitations

Laboratory results may not perfectly reflect real-world industrial conditions. Legal frameworks can be complex and vary significantly by region.

Reliability & validity

The use of SFS standards lends reliability to the lab procedures. Validity is supported by the inclusion of economic and legislative factors, though the legislative aspect may require further external validation.

Think critically

How can design innovation overcome legislative barriers to enable the widespread adoption of waste valorization technologies?
