Trunkbay

What Trunkbay does

Trunkbay (TRUNKBAY S.L) is a Spain-based environmental consulting and technology firm headquartered in Cobeña, Madrid, with a workforce of 1–10 employees. The company serves primarily Spanish SMEs, self-employed professionals, educational institutions, pharmacies, and public entities that lack in-house environmental departments, positioning itself as a fully outsourced environmental function. Core offerings include the Plataforma de Gestión de Residuos — a modular waste-management software with mobile applications and hardware integration for waste producers — together with the proprietary Flexibuster™ technology for converting organic waste into energy and fertilizer, and integrations with the public Plataforma E-SIR and MITECO for regulatory submissions.

Revenue is generated through professional services (sustainability consulting, environmental authorizations, ISO certifications, carbon footprint calculation, circular economy planning, GDPR adaptation, whistleblowing channels, and equality plans) and through recurring software subscriptions for the waste management platform. Pricing is quote-based with multi-year contracts; no public price list is published. The go-to-market is sales-led and direct, relying on inbound content marketing (blog, newsletter, SEO), phone/email outreach, and nationwide Spanish coverage. The business is independent and founder-operated, with no disclosed external investment, parent company, M&A activity, or leadership transitions.

Emerging players

• Greenomy: EU-focused regulatory technology platform automating CSRD, EU Taxonomy, and sustainability reporting for companies and advisors. Comparable to Trunkbay's environmental documentation platform ambition, though Greenomy is purpose-built for upcoming EU disclosure regimes.
• Sphera: ESG and operational risk management software provider offering carbon accounting, sustainability reporting, and EHS platforms. Comparable to Trunkbay's Plataforma de Gestión de Residuos vision, but serves larger enterprises with a more mature SaaS platform.

Regional players

• AENOR: Spain's leading certification body issuing ISO 9001, 14001, 27001, and other management system certificates. A direct peer for Trunkbay's ISO consulting practice, with a uniquely dominant Spanish footprint and trusted brand among Spanish SMEs.
• Normec: European TIC group operating testing, inspection, certification, and environmental compliance services across multiple countries. Comparable to Trunkbay's environmental administration and certification work, primarily serving European SMEs and mid-market firms.
• OCA Global: Spanish-headquartered inspection, certification, and compliance group with environmental and ESG services. Operates in the same Iberian regulatory environment as Trunkbay and offers overlapping environmental compliance and certification support to SMEs and public institutions.

Broad incumbents

• Bureau Veritas: Global testing, inspection, and certification (TIC) major with extensive environmental services, ISO certification, and ESG advisory practices. Competes with Trunkbay in Spain for ISO 14001/9001/27001 certification work but operates across many other industries as well.
• TÜV SÜD: Global certification and testing body with significant environmental management systems, ISO, and sustainability service lines. Directly competes with Trunkbay for ISO certification mandates and has established presence in Spain.
• Carbon Trust: International climate and sustainability consultancy advising organizations on carbon footprint reduction, certifications, and net-zero strategies. Closely parallels Trunkbay's carbon footprint calculation and circular economy service lines, but at much larger enterprise scale.
• SGS: World-leading TIC company offering environmental compliance, sustainability, and certification services. Comparable to Trunkbay's ISO certification, waste documentation, and ESG consulting services, though SGS operates at vastly larger scale across all major economies.

Direct peers

• EcoAct (an ENGIE Impact company): European climate and sustainability consultancy offering carbon footprint calculation, ESG advisory, and net-zero strategy services. Highly comparable to Trunkbay's sustainability consulting and carbon footprint practice, though EcoAct serves larger enterprise clients across multiple geographies.
