No-Trash Triangle Initiative

What No-Trash Triangle Initiative does

No-Trash Triangle Initiative (NTTI), legally Yayasan Segitiga Non Sampah, is an Indonesia-registered nonprofit founded in 2018 and headquartered in Manado, North Sulawesi. The organization is dedicated to protecting the Coral Triangle from plastic pollution, operating across four interconnected pillars: waste management, education and awareness, research, and corporate responsibility. Its core operations consist of intercepting ocean-bound plastic through 20 river barriers in Manado city, sorting and aggregation facilities on Bangka Island and in Manado, and regular waste collection services across the islands of Bangka, Gangga, Bunaken, Siladen, and Lembeh. NTTI also runs the School on the Beach environmental education program for local junior high students (Ocean Ambassadors), supports a research scholarship program with multiple German and Indonesian universities, and partners with resorts on CSR-aligned waste programs.

NTTI's business model is grant- and donation-driven rather than commercial. Funding comes primarily from GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit) through the 3RproMar program, supplemented by donations from European and North American supporters, a long-term co-financing partnership with IndieClime, and corporate alliances including GOT BAG (circular-economy PET upcycling) and Ultima Frontera (tour-operator profit-share). Service-side revenue consists of resort partnership fees for waste collection and spot-market sales of recyclable materials. The organization publishes annual reports with transparent, traceable tonnage data — exceeding 800 tons of ocean-bound plastic collected cumulatively, with >60.7 tons from islands, >100 tons from rivers, and >65 tons from schools in 2025 alone.

Operationally, NTTI runs a small core team (approximately 6 employees) led by Project Lead Anna Clerici and Board Chair Amelia Tungka, with founders Jens Hamprecht and William McDonough providing strategic oversight. The model is explicitly designed around the four pillars to deliver coordinated impact: physical waste interception, community education, scientific research, and shared-responsibility corporate engagement, with measurable outcomes reported through annual publications.

Direct peers

• Waste Free Oceans: European-based nonprofit collaborating with NTTI on Extended Producer Responsibility (EPR) pilots. Comparable as a peer organization focused on EPR-driven waste interception and corporate partnerships in the marine-plastic space.
• Plastic Bank: Social enterprise that collects ocean-bound plastic in coastal communities and exchanges it for income, then processes it into recycled feedstock. Most direct comparable to NTTI in mission (intercepting plastic from coastal/riverine sources) and community-engagement model.
• Trash Hero: Decentralized volunteer-driven cleanup movement with chapters across Southeast Asia, focusing on community action and education. Comparable to NTTI in community-engagement and education-pillar emphasis, though less focused on permanent infrastructure.
• Sungai Watch: Indonesia-based nonprofit deploying river barriers and waste-sorting stations to intercept plastic before it reaches the ocean. Operates a near-identical river-barrier-plus-sorting-facility model and is the closest direct geographic peer to NTTI.
• ROLE Foundation: Indonesia-based nonprofit focused on zero-waste education, community empowerment, and marine conservation in Bali. Comparable to NTTI in Indonesia-based nonprofit model combining waste management, education, and community engagement.
• Seven Clean Seas: Plastic-offset company funding coastal plastic recovery and river cleanup projects across Southeast Asia. Comparable to NTTI in river/coastal collection focus and B2B funding partnerships, though structured as a social enterprise.
• 4ocean: Commercial-funded cleanup operation that funds ocean plastic removal through product sales. Comparable to NTTI in funding model that converts recovered material/brand engagement into operational revenue, though operating in a different geography.

Broad incumbents

• The Ocean Cleanup: Large-scale marine plastic cleanup organization deploying technology-driven ocean and river interception systems. Comparable mission around ocean-bound plastic, but operates at significantly larger scale and uses different technological approaches.

Regional players

• Coral Triangle Center: Regional foundation dedicated to Coral Triangle marine conservation, training, and sustainable fisheries. Comparable to NTTI as a regionally-focused Coral Triangle conservation organization, though focused more on ecosystem management than waste collection.

Emerging players

• Seabin Foundation: Deploys smart floating bins and ocean-cleanup technology in marinas and waterways. Comparable to NTTI as a marine-debris-interception organization, but focused on technology deployment in marinas rather than community-scale river barriers.
