Papa Boom advances methane to nitrate composter with FasterCapital support
Dateline Madrid, Spain & Dubai, UAE — Mar 18, 2026
Papa Boom S.L, an existing participant in FasterCapital’s execution program, reported this week on multiple technical and operational milestones following a presentation at Madrid’s AgroBank Tech Digital INNovation event, with ongoing support from FasterCapital. The startup showcased a new technology capable of capturing methane, CO₂ and nitric oxide from waste streams and transforming them into nitrites, nitrates and other compounds useful for biomass recycling and composting under controlled conditions.
With continued collaboration from FasterCapital through Launchup, Papa Boom is focused on advancing its prototype composter ecosystem, validating microbial interactions in volatile‑rich waste packaging, and preparing evidence packages for regional awards and stakeholder engagement.
What the Startup Delivers?
- A prototype composter that modulates the micro‑ecosystem inside waste packaging to transform volatile and aromatic molecules into a more controlled degradation process that can improve health conditions during treatment.
- A gas‑capture and conversion technique designed to intercept methane, CO₂ and nitric oxide and redirect them into nitrites, nitrates and related compounds for recycling use in composting and urban waste‑treatment systems.
- Microbiological research linking terpenes and oncomicrobiome‑associated microbes to specific stages of waste degradation, informing how aroma chemistry and chirality influence cellular respiration in bacteria and fungi.
Current FasterCapital Support
FasterCapital’s ongoing contribution in this phase includes: - milestone planning and execution follow‑up as the prototype advances; - fundraising readiness support and preparation of evidence for awards and stakeholders; - pitch and communications refinement for investor and public audiences; - introductions to relevant ecosystem stakeholders and technical partners where appropriate; - strategic prioritization of near‑term validation and demonstration activities.
Current Execution Priorities
Papa Boom’s current priorities are focused on continued prototyping and controlled‑atmosphere tests of its composter, further microbiological mapping of terpene microbe interactions, preparing documentation for the Aragón Emprende application, and planning next demonstrations with municipal and industry contacts.
Leadership Comment
Hesham Zreik, Founder and CEO of FasterCapital, said: ‘We’re pleased to continue supporting Papa Boom S.L through Launchup. Our team is focused on current execution priorities, milestone tracking, and connecting the startup with relevant ecosystem stakeholders as it advances.’
