How Restum Works

Restum is a B2B marketplace for surplus and used construction materials in Germany. Companies can buy and sell leftover materials — sustainably, simply, and securely.

Restum is designed for businesses — construction companies, tradespeople, project developers and other firms with surplus materials or looking to buy at below-market prices. Private individuals cannot register.

Restum is currently available in Germany. Expansion to further European markets is planned.

Enter your company details and provide your company registration number. Our team reviews your application and typically verifies your account within 1 working day. You will receive an email notification once your account is approved.

Verification ensures that only legitimate businesses trade on the platform. This protects all parties from fraud and builds trust in every transaction.

Typically 1 working day. If information is incomplete it may take longer — we will contact you by email in that case.

Payments are processed via SEPA bank transfer. Your funds are held in escrow and only released to the seller after you confirm pickup. You are always protected.

If pickup does not take place or the material is not as described, you can raise a dispute within the settlement period. Our support team reviews the case and a refund will be issued where appropriate.

After successful payment you receive the seller's contact details and can arrange pickup directly. The pickup location is shown in the listing.

Yes. All companies on Restum go through verification before they can list or buy. You always trade with verified business partners.

You can list all types of surplus construction materials: tools, cables, insulation, tiles, steel, doors, windows, PPE and more. Materials must come from a business — no private sales.

Scan the product barcode or enter the EAN manually. Restum automatically fills in product data and CO₂ information. Add photos, condition, quantity and pickup location — your listing goes live in minutes.

Payout is processed automatically after the buyer confirms pickup. Funds are typically transferred to your account within 1–2 working days.

Restum charges a commission on successful transactions. Please refer to our Terms & Conditions or contact us directly for exact rates.

For every transaction, Restum automatically calculates the CO₂ emissions saved based on the material and quantity. You can use this data for ESG reporting and public procurement tenders.

Restum does not store full IBAN data. Payments and payouts are processed via Stripe, a certified payment provider (PCI-DSS compliant). Your bank details never leave Restum in plain text.

Your company data is only visible to verified platform users and is not shared with third parties. See our Privacy Policy for details.
