Animal Welfare in the Circular Economy: Reducing Harm in Resource Cycles

The circular economy aims to eliminate waste through recycling and regenerative use of resources. Understanding how circular economy principles interact with animal welfare helps identify synergies and conflicts.

Key Facts

Food waste fed to pigs (swill feeding) was traditionally a circular practice -- now banned in many countries due to disease risk
Insect farming converts food waste into protein but raises welfare questions about insect sentience at scale
Leather tanning using plant-based tannins can replace chromium-based processes with lower environmental impact
Wool is often cited as a circular fibre but mulesing and live export welfare concerns complicate the narrative
Rendering plant by-products from slaughter are used in pet food, fertiliser, and industrial applications
Regenerative agriculture with pasture-raised livestock integrates animal farming into soil carbon cycles
Animal agriculture uses approximately 70% of global agricultural land -- its circular integration involves enormous scale

Welfare Considerations

The circular economy framework creates both opportunities and risks for animal welfare. Opportunities include using food waste as animal feed (reducing feed crop demand), integrating livestock into soil fertility cycles (reducing chemical fertiliser use), and incentivising higher-welfare slower-growing animals as a feature of regenerative systems. Risks include intensification of insect farming to process waste streams at scale, and greenwashing of welfare-poor animal products by associating them with circular or regenerative credentials. Welfare advocates should engage with circular economy policy to ensure animal welfare standards are built into circular agriculture frameworks rather than afterthoughts.

What You Can Do

Advocate for animal welfare standards to be included in regenerative and circular agriculture certification schemes
Support food waste reduction initiatives that decrease pressure on animal feed production systems
Choose wool and leather products from producers that meet welfare standards throughout the supply chain
Push for insect welfare research to inform circular economy applications of insect farming at scale
Engage with circular economy policy processes to ensure animal welfare is a design criterion, not an add-on
