Kemakta Konsult

What Kemakta Konsult does

Kemakta Konsult AB is an employee-owned (personalägt) environmental consulting firm headquartered in Stockholm, Sweden, founded in 1975 and operating with approximately 20 staff comprising civil engineers and PhDs across chemistry, radiation physics, hydrogeology, and geoscience. The firm delivers specialized services across eight practice areas: contaminated land investigations, water and environmental quality, waste management and recycling, hydrogeology and contaminant transport, nuclear facility technical investigations, final-disposal safety assessments, advanced numerical modeling, and nuclear site clearance (friklassning). Its core differentiator is long-cycle safety-analysis work for nuclear waste repositories, executed through proprietary models including DOS2U (dose consequence), Marfa-NR (radionuclide transport), helium-4 groundwater age dating, oxygen-ingress modeling, and a site-specific Kd-value database for Forsmark bedrock, layered on commercial platforms such as Ecolego and Comsol Multiphysics.

The firm serves a concentrated set of Nordic public-sector and enterprise clients. Anchor relationships include SKB (Svensk Kärnbränslehantering AB) for nuclear-waste repository safety assessments including the SFR extension, SSM (Strålsäkerhetsmyndigheten) for regulatory and decommissioning support, SGU (Sveriges geologiska undersökning) for geological and contamination investigations, and Stockholm's Exploateringskontoret for urban-development contamination assessments. International work is performed for Finland's Posiva (TURVA 2020 safety case) and Swedish energy company Vattenfall (Ågesta decommissioning). GTM is sales-led, project-based, and secured through framework agreements (ramavtal) with government buyers and direct enterprise engagements; revenue derives entirely from professional service fees on a quote-driven basis with no disclosed pricing or recurring subscription model. Marketing relies on scientific publications, conference participation (Renare Mark, SSM seminars, NICOLE), and case studies rather than paid channels.

Kemakta is privately held with no disclosed external investors, no parent company, and no subsidiaries. Its competitive position rests on the rarity of credentialed nuclear-geochemistry talent, decades of regulatory-process experience under Swedish nuclear law, and proprietary modeling IP accumulated through multi-decade SKB research programs. Risks include high customer concentration with SKB as an anchor, dependence on the Swedish/Finnish nuclear decommissioning and new-build pipeline, and the absence of any productized or AI-enabled service layer that could scale beyond billable consultant hours.
