What NutriLoop does
NutriLoop OÜ is an Estonian private social enterprise founded in 2020 and headquartered in Tallinn that operates a closed-loop biowaste valorization business. The company collects food and organic waste from offices, restaurants, and municipalities using proprietary air-tight containers that initiate on-site fermentation with beneficial microorganisms (lactobacillus and fungi); collected waste is then processed at a biowaste valorization center in Tallinn using bacteria and earthworms into two commercial output streams. The first is consumer hardware: the proprietary two-chamber Tumbler Composter (200L priced at €449 and 340L at €699), manufactured in Estonia, claimed to deliver 10x the productivity of conventional composters via continuous aeration from drum rotation. The second is NutriActivator, a liquid biofertilizer (N-P-K ratio 2.4-0.29-1.6) containing photosynthetic and lactic acid bacteria, beneficial fungi, fulvic and humic acids, sold as a 450ml spray (€9.90), concentrate (€19.90), or bundle (€24.90) through the products.nutriloop.org e-commerce store.
The go-to-market combines direct-to-consumer e-commerce across Estonia and Europe (via Omniva and Itella, with payment integration through Maksekeskus bank links) with a B2B biowaste collection subscription service targeting corporate offices (LHV, Lift99, Utilitas), restaurants in Telliskivi Creative City and Balti Jaam Food Market, and municipalities (Keila, Tallinn Strategy Center pilots). Reference pilots include a year-long kindergarten/school composting study with the Tallinn Strategy Center and a closed-loop balcony garden pilot with LHV bank. The revenue model mixes one-time product sales, recurring B2B service contracts, and EU grant funding; NutriLoop is a partner in the Horizon2020 SEA2LAND project (€7.7M total budget, 26 partners across 11 countries), contributing advanced fermentation technology and receiving R&D support from the Estonian Crop Research Institute. The company is founder-led by CEO Ingrid Hermet, with Markko Mäll, Madis Tilga, and additional team members Siim Raadik (CTO) and Marko Krist (CMO); it has received minimal external capital to date and remains small (1-10 employees), positioning itself primarily on regulatory tailwinds from the EU's mandatory separate biowaste collection regime and recycling targets (55% by 2025, 65% by 2035).

Product offeringCore offering
NutriLoop runs a community bio-circular service that collects bio-waste from offices and restaurants, valorizes it through fermentation with beneficial microorganisms (lactobacillus, photosynthetic bacteria, fungi) and earthworm vermicomposting, and converts it into the NutriActivator line of liquid biofertilizers (N-P-K 2.4-0.29-1.6). It sells physical tumbler composters (200L and 340L, two-chamber systems made in Estonia) and NutriActivator spray, concentrate, and bundle products directly through its e-commerce store, and delivers personalized biowaste collection services to corporate offices, food markets, and municipalities across Estonia and Europe.
Product overview
NutriLoop is a circular economy company transforming the food system by converting bio-waste into regenerative agricultural products. The product portfolio consists of two categories: (1) Tumbler Composters (200L and 340L) - proprietary composting equipment made in Estonia that enables efficient on-site bio-waste composting with a two-chamber system; and (2) NutriActivator fertilizers - a line of liquid biofertilizers (spray, concentrate, and bundle) made from fermented food waste containing photosynthetic bacteria, lactic acid bacteria, beneficial fungi, and fulvic/humic acids. The products work together as a complete circular economy solution where bio-waste is collected from restaurants and offices, processed through fermentation, and returned as soil-enriching biofertilizers for regenerative food production.
