Tens of thousands of kg of avocado seed are landfilled every month in the GTA. SeedCircle converts it.
One circular supply chain. One standardised extraction. Two material streams feeding three products.
Ontario is Canada's primary avocado import gateway and hosts the country's densest cluster of Tier-1 food-service processors, which currently landfill large volumes of avocado seed at zero value. SeedCircle diverts that waste stream into a controlled, traceable, cold-chain raw-material pipeline and one standardised extraction — yielding a polyphenol/acetogenin extract and a starch that feed FreshGuard™, VitaFilm™ and PhytoGuard™ at near-marginal cost.
Five-Node Control Architecture
Not availability. Control.
SeedCircle is not a volume argument — it is a control architecture. Inconsistent raw material is the most common reason biopesticide and natural-product ventures fail at scale, and it is exactly what GFSI-certified buyers screen for. PMRA product chemistry, food-grade lot release, and investor due diligence all require evidence of supply-chain control: batch segregation, cold-chain specification, standardisation parameters, and chain-of-custody documentation.
Avocado seed diverted from Ontario Tier-1 food-service processors that currently landfill it. Framed as waste diversion — zero or negative cost, mutual circular-economy / ESG credentials, and administratively simpler than a procurement contract. Indicative GTA availability is on the order of tens of thousands of kilograms per month; pilot scale needs well under 3% of it.
From the moment of collection, each lot is tagged with processor ID, variety, collection date and intended product stream — the foundation of chain-of-custody and PMRA product-chemistry identity documentation.
Polyphenol degradation accelerates above 4°C, catalysed by polyphenol oxidase. Specification: 0–4°C transport from processor to facility and rapid transfer from processing to refrigerated storage before extraction. Any documented cold-chain breach is flagged in the lot record.
A single standardised ultrasound-/microwave-assisted aqueous extraction (UAE/MAE — the route behind the lead citrus evidence) splits each seed into a polyphenol/acetogenin extract and a starch. Lot-release specification: total polyphenol content, marker-compound profile, persin within spec, microbial limits — a certificate of analysis on every batch.
The extract feeds FreshGuard™ and PhytoGuard™; the starch feeds VitaFilm™. Fixed infrastructure is shared across all three lines, so each incremental product carries near-marginal cost and each diversion agreement is justified by the combined demand of all three — strengthening the unit economics of the whole platform.
Volume Architecture
Less than 3% of available GTA supply powers all three products at pilot scale.
Processor Partners
GTA Tier-1 food-service processors — diversion targets.
Highest-volume avocado-seed waste streams; waste-diversion framing with zero or negative cost and documented circular-economy credentials.
Existing corporate sustainability commitments make waste-diversion programmes administratively compatible.
Proximity to the import gateway and to fresh-cut customers is operationally advantageous for collection logistics.
ESG & Circular Economy
Waste to value. Chain-of-custody documented.
The SeedCircle chain-of-custody document set for each batch includes the processor waste-diversion agreement; the batch collection log (lot ID, processor ID, collection date, cold-chain compliance); the processing log; the standardisation certificate of analysis (total polyphenols, marker compounds, persin spec, microbial limits, lot-release sign-off); and the delivery record. This documentation chain supports both PMRA product-chemistry identity requirements and third-party ESG certification for premium market positioning — and is the same documentation GFSI-certified buyers already require.
Platform Complementarity
One supply chain. Two streams. Three food-grade products.
Anti-browning agent for fresh-cut fruit, from the extract stream. A Health Canada food additive — fastest to market, funding the platform while PhytoGuard™ matures.
FreshGuard →Active-packaging and edible films from the starch stream — the fraction an extract-only business would landfill. Cleared via a Health Canada Letter of No Objection.
VitaFilm →Bio-antifungal postharvest decay control, from the extract stream. A PMRA biopesticide (~18–24 months) — the defensible barrier a fast-follower cannot shortcut.
PhytoGuard →
