Direct answer
Characterise feedstock and required output purity first; sorting technology selection and the entire business case follow from those two variables.
Typical challenges in this sector
- Feedstock composition varying by season or supplier
- Output purity below offtake specification
- Manual sorting dominating labour cost
- High reject volume and disposal cost
- Offtake pricing linked to quality grades
Automation and engineering opportunities
Mechanical pre-treatment
Shredding, screening and density separation.
Sensor-based sorting
NIR, X-ray, induction and colour sorting to purity targets.
Robotic sorting
AI-guided picking for residual streams and quality control.
Output quality control
Continuous purity monitoring linked to grade documentation.
Engineering and project considerations
- Feedstock characterisation over a full seasonal cycle, not a single sample
- Offtake contracts should precede the investment decision where possible
- Purity specification determines sorting stages and cost
- Permitting and environmental compliance are on the critical path
- Recycling projects frequently access green and circular-economy financing
What to prepare before engaging engineering companies
- Feedstock composition analysis over time
- Target output grades and purity specifications
- Offtake interest or contracts
- Permitting status and environmental requirements
What to measure
Frequently asked questions
What do lenders scrutinise in recycling projects?
Feedstock security, output offtake and purity evidence. Technology risk is usually secondary to those three.
