What Konvex does

Konvex AB is a Swedish processor of animal by-products founded in 1957 and headquartered in Lidköping, Sweden. The company operates a nationwide collection and processing network serving Swedish slaughterhouses, handling category 1, 2, and 3 animal by-products across two production facilities—Krutmöllan in Kävlinge (southern Sweden, established 1957) and Mosserud in Karlskoga (central Sweden, established 2006). Konvex is a wholly owned subsidiary of Daka Denmark A/S, which is itself owned by the German family-owned company Saria SE & Co. KG; Danish Crown is another major shareholder. The company employs approximately 30 people across its facilities and head office.

The company's core technology is the proprietary Biomal concept, co-developed with S.E.P. Scandinavian Energy Project, which crushes and grinds animal by-products into a biofuel with energy content equivalent to wood chips. Biomal is usable in conventional fluidized bed boilers for combined heat and power generation, pumped into the furnace via a closed system. The Karlskoga facility is the world's first factory purpose-built for Biomal production. Materials from southern Sweden are consolidated at Krutmöllan and exported to Denmark for biodiesel extraction, while materials from Jönköping and northern Sweden are processed into Biomal at Karlskoga.

Konvex generates revenue primarily through usage-based reception/collection fees charged to slaughterhouse customers for guaranteed pickup services, supplemented by Biomal product sales delivered to category 1-approved heating plants. Pricing follows periodic adjustments tied to energy, fuel, and spare parts costs (3% in 2024 and 2025, with a June 2026 adjustment). The go-to-market is B2B and sales-led, with new customers onboarded via phone and existing customers scheduling pickups through an online portal. The company also operates veterinary crisis response services in coordination with government authorities and runs the Svensk Lantbrukstjänst subsidiary for livestock farmers and horse owners.

Core offering

Konvex AB is a Swedish B2B waste management company that guarantees collection of animal and vegetable by-products (categories 1, 2, and 3) from slaughterhouses throughout Sweden. The company processes these by-products into two primary outputs: biodiesel feedstock (exported to Denmark from the Krutmöllan transshipment facility) and Biomal, a proprietary biofuel produced at the Karlskoga factory for use in fluidized bed boilers. Additional services include veterinary crisis management for epizootic and notifiable diseases, and through its subsidiary Svensk Lantbrukstjänst AB, animal collection, euthanasia, and cremation services for farmers and horse owners.

Product overview

Konvex offers a unified service portfolio centered on animal by-product management within Sweden's circular economy. The core offering consists of collection and processing services for residual products from slaughterhouses, with by-products from southern Sweden exported to Denmark for biodiesel extraction and materials from Jönköping and northward processed at the Karlskoga facility into Biomal—a proprietary biofuel. Supporting services include the Biomal Concept (the company's flagship sustainable fuel product), veterinary security crisis response, and subsidiary Svensk Lantbrukstjänst for agricultural and farm customers. The company operates two production facilities in Mosserud (Karlskoga municipality) and Krutmöllan (Kävlinge municipality).
