The Ocean Cleanup Partnership: how to apply

By Andrew Holden

Getting a shot at anchor-funder backing for river plastic interception is rare. This post walks through exactly what the Optiver Foundation is looking for, whether your organisation fits, and how to put together the strongest possible application.

What this opportunity actually is

The Optiver Foundation is the grant-making arm of the trading firm Optiver. It operates as a genuinely independent non-profit with two focal areas: restoring nature and expanding access to STEM education. This partnership sits squarely in the first pillar.

The Foundation has positioned itself as anchor funder for a proof-of-concept deployment of The Ocean Cleanup's Interceptor technology in Mumbai, capturing river plastic before it reaches the ocean. That framing matters: this is not a research grant or a feasibility study. The Foundation wants a working system in the water, in a high-impact city, demonstrating that large-scale river plastic interception is replicable. The amount listed is "see listing," so the figure is disclosed on the detail page rather than here, and the deadline is not publicly confirmed at time of writing.

Who should apply

The explicit eligible organisation types are nonprofits and social enterprises. Commercial for-profits without a social-enterprise structure are outside scope based on the available data.

On stage, the Foundation accepts both prototype-pilot organisations and those at scale-mature stage. That is a deliberately broad range, but read it in context: this is a proof-of-concept deployment, not a first-time experiment. You need enough operational credibility to actually put hardware in the water in Mumbai, manage local stakeholder relationships, and report results to a foundation that expects scientific rigour.

Geographically, the grant covers India and has global scope, but the specific deployment is Mumbai. If you are not already operating in India, or cannot credibly demonstrate a pathway to doing so, that is a significant obstacle to address head-on in your application.

The ideal applicant looks like one of the following:

  • An organisation already partnered with The Ocean Cleanup, or one that has had formal conversations about Interceptor deployment
  • A nonprofit or social enterprise with existing river or coastal plastic programmes in South Asia, particularly Maharashtra or the broader Mumbai metropolitan region
  • A scaling entity that has run a successful proof-of-concept elsewhere and is now seeking anchor funding to replicate in a high-pollution geography

If none of those descriptions fit your organisation precisely, the key question is whether you can demonstrate alignment with the Interceptor model rather than a formal partnership. The requirements leave some room for that interpretation.

What they are looking for

The Foundation describes itself as favouring "science-based, technology-enabled solutions." Every selection criterion flows from that commitment. Here is how to translate each stated requirement into what a strong application actually shows.

Partnership with The Ocean Cleanup or alignment with the Interceptor model

A formal partnership letter or memorandum of understanding with The Ocean Cleanup is the clearest proof here. If you do not have one, document every substantive conversation, any technical exchange, or any shared pilot work. Explain specifically why the Interceptor system is the right technology for your target geography and why your organisation is the right delivery partner.

Focus on river plastic interception in Mumbai or similar high-impact geographies

"Similar high-impact geographies" is the language in the requirements, so the Foundation may consider proposals outside Mumbai if the case for impact is compelling. That said, Mumbai is named explicitly in the programme summary, so you should treat it as the primary target and justify any deviation with data on plastic load, river system characteristics, and comparative impact projections.

Technology-driven proof-of-concept or scaling of plastic waste capture systems

This requirement distinguishes the programme from awareness campaigns, advocacy, or community clean-up models. Your application needs to describe the specific hardware or system being deployed, the metrics by which success will be measured (tonnes intercepted, percentage of plastic load captured, operational uptime), and who is responsible for technical maintenance and monitoring.

Demonstrated commitment to preventing ocean plastic pollution at source

"At source" is doing real work in that phrase. The Foundation is not funding beach clean-ups or downstream recovery. Your track record, theory of change, and programme design must all point upstream: reducing the volume of plastic that ever enters waterways in the first place.

Beyond the technical requirements, the Foundation's stated values include gender equality and STEM education access. These are not listed as grant criteria for this specific partnership, but weaving them in where authentic (for instance, workforce development components, community science engagement, or local STEM partnerships) may strengthen an application at the margins.

How to apply

The data available does not specify whether a letter of intent or pre-application call is required. Given the Foundation is acting as anchor funder for what appears to be a structured programme rather than an open grant round, the most prudent first step is direct outreach to the Optiver Foundation before submitting anything formal.

Concretely:

  1. Research the programme status. Visit the full listing on Raise Lens for the disclosed amount, any deadline, and the submission route. These details may be updated as the Foundation publishes more.

  2. Establish or confirm your relationship with The Ocean Cleanup. If you do not already have a formal connection, initiate contact with The Ocean Cleanup's partnerships team before approaching the Optiver Foundation. Coming to the Foundation with a joint or co-designed proposal is substantially stronger than coming with a unilateral concept.

  3. Prepare your proof-of-concept documentation. This should include: a technical deployment plan (site selection, installation timeline, operational model), prior results from any comparable deployment, your organisation's legal status and financials, and any local authority permissions or community engagement agreements relevant to Mumbai.

  4. Draft your narrative around outcomes, not activities. The Foundation funds "transformative solutions." Frame your application around the measurable change in plastic entering the ocean, not the process of installing the device. Include a monitoring and evaluation plan with defined milestones.

  5. Submit via the route specified in the listing. Until the Foundation publishes a formal application portal or submission address, treat the Raise Lens listing as your reference point for updates.

Use this in Raise Lens

Start by saving this opportunity to your account and setting a deadline alert so you are notified the moment a closing date is confirmed. From the detail page you can also track any updates to the amount or submission route as the Foundation publishes them.

To find comparable live grants and tenders running alongside this one, head to the /opportunities feed and filter by the ocean and blue economy sector: the crawlable grant hub at /sectors/ocean-blue-economy/grants surfaces all active opportunities tagged to this space, and /sectors/waste-reduction/grants catches overlapping programmes focused on plastic and waste interception specifically.

Use the /funders directory to research the Optiver Foundation's broader grant-making history and to identify other foundations active in ocean plastic and circular economy funding, so you are building a pipeline rather than betting everything on one application.

Finally, subscribe to /wire briefings to track the latest signals in ocean plastic funding: new programmes, funder announcements, and policy developments that affect the competitive landscape for this type of proof-of-concept work.

If your organisation has the technical partnerships and on-the-ground presence to make a Mumbai Interceptor deployment credible, this is a rare opportunity to secure anchor funding from a foundation explicitly looking to seed exactly this kind of proof-of-concept work.
