Polish engineering SME specializing in heat recovery, energy efficiency, and circular resource management across buildings, industry, and agriculture.
IZNAB is a Polish engineering SME specializing in energy and resource efficiency solutions for industrial and building applications. Their core work involves designing and implementing heat recovery systems, waste valorization processes, and energy management tools for process industries, buildings, and industrial parks. They contribute technical expertise in thermal engineering — from district heating and smart building retrofits to metallurgical furnace heat recovery and greenhouse climate control using thermochemical fluids. Across their portfolio, they consistently bridge the gap between industrial waste streams (heat, materials, water) and their productive reuse.
Central to MAESTRI (process industries), CIRMET (metallurgy furnace heat recovery), INCUBIS (waste heat in industrial parks), InDeal (district heating), and Heat4Cool (building retrofitting).
Heat4Cool (solar-assisted heat pumps for retrofitting), InnoWEE (prefabricated components from waste materials), and InDeal (district heating/cooling) all target building energy systems.
URBANREC (bulky waste recycling), CIRCULAR FOAM (end-of-life foam recycling, chemical recycling), and CIRMET (valorization of industrial wastes) demonstrate materials circularity expertise.
INCUBIS focuses on industrial symbiosis incubators for maximizing waste heat efficiency in eco-industrial parks; MAESTRI addresses resource management in process industries.
TheGreefa applies thermochemical fluids for temperature/humidity control and water recovery in greenhouse farming — a distinctive cross-sector application.
MODEL2BIO develops modelling tools for valorizing agri-food residual streams in bio-based industries.
IZNAB's early H2020 work (2015–2019) concentrated on building-level and district-level energy solutions — smart retrofitting, prefabricated building components, district heating, and process industry energy management (MAESTRI, InDeal, InnoWEE, Heat4Cool). From 2018 onward, their focus shifted decisively toward industrial-scale resource circulation: metallurgical waste heat recovery (CIRMET), industrial symbiosis in eco-industrial parks (INCUBIS), plastics chemical recycling (CIRCULAR FOAM), and agricultural waste stream modelling (MODEL2BIO). The trajectory shows a clear move from single-building energy efficiency toward system-level industrial ecology and circular economy applications.
IZNAB is moving toward integrated industrial ecology — expect future work in cross-sector waste exchange platforms, defossilisation pathways, and circular manufacturing systems.
IZNAB operates exclusively as a consortium participant, never taking the coordinator role across all 10 projects. With 141 unique partners across 22 countries, they are a highly networked SME that integrates into diverse, large consortia rather than returning to the same partners repeatedly. This pattern suggests they are a flexible technical contributor valued for specific engineering capabilities — easy to integrate into new teams and likely responsive to consortium needs rather than driving the research agenda.
IZNAB has built a remarkably wide network for an SME: 141 unique consortium partners spanning 22 countries across Europe. Their participation in both Innovation Actions and Research & Innovation Actions gives them connections across the full spectrum from applied research to near-market deployment.
IZNAB occupies an unusual niche as a Polish engineering SME that works across the full thermal energy chain — from building heat pumps to metallurgical furnace recovery to greenhouse climate control. Their ability to apply heat and resource recovery principles across very different sectors (construction, heavy industry, agriculture) makes them a versatile partner for cross-domain projects. For consortium builders, they offer practical engineering delivery in energy and waste systems without the overhead of a large organization, backed by a proven track record across 10 completed or ongoing H2020 projects.
