INSPIRE - INSect-based PlastIc Recycling rEvolution

Important results from the project

All project goals were met. INSPIRE developed and validated in silico designs for two core subsystems of a container-scale insect-based plastic waste bioconversion system: a semi-continuous larval rearing conveyor and an electromagnetic feeding device. Both achieve strong unit economics well below high-tech alternatives. The project also generated two scientific publications, two active pilot clients, and advanced investor and EU funding discussions.

Expected long term effects

INSPIRE lays the foundation for a cost-effective, scalable technology to valorise currently unrecyclable plastic waste streams through insect bioconversion. The container-scale, decentralised format enables broad industrial adoption. Dual outputs - larvae as alternative protein and frass as fertiliser - create multiple revenue streams supporting circular economy objectives. The project strengthens Sweden´s position in insect-based innovation and contributes to EU plastic waste reduction targets.

Approach and implementation

INSPIRE followed a staged, iterative "smart tech" approach across two phases. Each stage combined in silico modelling, techno-economic analysis, and IP assessment. The project ran on schedule with disciplined budget execution. One unplanned but productive development occurred: low-cost cardboard prototyping was introduced in Stage 2, enabling a well-justified design pivot. No external factors negatively impacted the project.
