What Covexio does.

📋
Waste Passport

Digital material card: composition, hazard class, volume, SDS document, QR code. Private fields revealed after NDA only.

🔒
KYB Verification

Only VAT-registered verified companies access material data. E2EE encryption — zero-knowledge server architecture.

🔄
Smart Matching

SQL-based scoring: category compatibility, volume fit, hazard class, and distance. AI-assisted matching in v2.

✍️
NDA + Deal Flow

In-app NDA e-signing (eIDAS AES), Signal Protocol encrypted chat, deal status pipeline, PDF contract generation.

📊
ESG Dashboard

Real-time CO₂ saved, tonnes exchanged, disposal cost avoided. One-click CSRD-ready report + MATIS CSV export.

🗺️
Cluster Map

All verified partners on interactive port map. Anonymised material flow heatmap for the cluster. Built with OpenStreetMap.

Zero-knowledge by design.

KYB Verification

VAT number check via Belgian BCE/KBO cross-reference. Manual admin approval. Account freezing during recovery.

E2EE Architecture

Password → Argon2id → Master Key (memory only) → HKDF per context. Files: Envelope E2EE (DEK + ECDH). Chat: Signal Protocol with forward secrecy.

TOTP MFA & Recovery SOP

Mandatory TOTP. Recovery Key generated once and stored offline. Admin escrow recovery via AWS KMS enforces a strict 7-day cooling period with video verification.

Disputes & Account Deletion

Secure incident logging with E2EE attachments. Deactivation hides listings. Deletion cryptographically shreds E2EE DEK rows, rendering data permanently unreadable.

GDPR Data Export

Owner-only action to generate a secure export ZIP containing all plaintext company parameters, materials, and ESG logs in JSON, alongside raw encrypted blobs.

Built for EU regulations.

CSRD

EU Corporate Sustainability Reporting Directive. Large in-scope companies report circular-economy (ESRS E5) and value-chain data from FY2027. One-click PDF report with CO₂ impact per deal.

MATIS

OVAM mandatory waste reporting (Jan 2024). JSON/CSV export compatible with MATIS format. Auto-generated from verified deal data.

VLAREMA

Waste vs Secondary Resource determination. Class I/II mandatory compliance checkbox. Liability transfer via ToS clause.

GDPR

Data residency in EU Frankfurt. Erasure = delete DEK rows — ciphertext becomes permanently inaccessible. 7-year audit retention.

Industrial symbiosis has real potential in the Antwerp chemical cluster — but today it happens manually, slowly, and without a digital layer. Covexio is building that layer. If your company generates by-products or sources secondary materials, let's talk. Industriële symbiose heeft echt potentieel in de Antwerpse chemische cluster — maar vandaag verloopt het manueel, traag en zonder digitale laag. Covexio bouwt die laag. Als uw bedrijf bijproducten genereert of secundaire materialen inkoopt, praten we graag.
