Smart coders are using blockchain tools to minimize waste & build the circular economy. Here they are:

1. Littercoin/

Along with CleanApp, Littercoin is an original player in the Clean[Block]Tech space. Launched by a self-taught developer, Seán Lynch, is the first service to offer blockchain rewards (Eth-based token called Littercoin) for generating geo-spatial information.

OLM has committed to making its crowdsourced data freely-available on an open-source basis. It has a growing community, and a mobile app that has the potential of becoming the easiest crypto-earning platform available globally. Not too shabby.

Needless to say, we’re big fans.

2. PlastX

PlastX describes itself as a marketplace where you can buy the plastic you need direct from the community. The project is headed by the same folks behind The Plastic Circle. In a nutshell, plastic collectors get paid to clean plastic in particular areas. Blockchain rewards are a natural fit.

3. WasteSpace is an Australian team. Here’s their description from Twitter: “Using blockchain technology to improve our environment by incentivizing people to pick up litter.”

The website is down as of December 2018, so it’s not clear whether they are defunct or in stealth development.

4. IBM Plastic Bank

Yup, Big Blue is hip to the game.

Working with IBM and service provider Cognition Foundry, The Plastic Bank ( is mobilizing recycling entrepreneurs from the world’s poorest communities to clean up plastic waste in return for IBM blockchain rewards that can be redeemed for life-changing goods.

The founding team is comprised of David Katz & Shaun Frankson (active since May 2013), and the team keeps growing in South East Asia and South America. Given IBM’s investment, this shows big potential.


Founded in January 2018, is the newest kid on the block. But it’s headed by a crew of Norwegians, so it’s also one of the coolest kids on the block. A few days ago they won this nifty prize. Congratulations!

The basic premise is similar to each of the projects above: pay people to pick up plastic, and redeem it for blockchain rewards. Empower’s distinguishing feature is provenance tracing — using blockchain mapping to trace the trash to particular producers.

CleanApp’s approach to provenance tracing is described in our U.S. utility patent, and subsequent Whitepaper. We can’t wait to learn more about Empower’s approach and do a massive mind-share with our new Nordic friends. If Norwegian Vikings could reach Newfoundland, their successors may be the heroes we need to eliminate the roots of our marine pollution problem — right at home.

6. Google

Yeah, yeah, yeah — we know what you’re thinking. But Google actions speak louder than words in terms of pollution tracking and mapping.

The main problems we see with Google’s approach is characterizing pollution tracking efforts as CSR-type “sustainability” or “special projects.” Google is a data company. These are the world’s largest untapped data opportunities. Google knows this because it is walking the walk; now it is time to talk the talk.

CleanApp has reached out directly to Google to get GoogleBrain to realize that there’s far more opportunity in treating these markets like … markets, rather than looking at pollution and waste data as a sandbox for prototyping new technologies that may one day lead to … markets.

Our petition needs your support. Please help.

7. Mattereum

Mattereum is in a league of its own. While technically not Clean[Block]Tech, the Mattereum litepaper makes clear that once we can track physical assets on blockchain, then the technical infrastructure is there for pollution tracking and carbon credit trading.

[Mattereum] opens up new solutions to problems such as climate accounting. These tokens could represent carbon offsets or credits, and assets could be set up to allow use only if the user has paid in enough carbon credits to offset the carbon produced in typical usage.

Inspired and inspiring. CleanApp is doing everything it can to help that effort.

8. @EthBounties

EthBounties is a ConsenSys project that allows anyone to create blockchain bounties for anything. Then the EthBounties team created bounties to cleanup waste. And here’s what happened:

Joseph Lubin (ConsenSys) broadcast this example in a recent tweet on the state of crypto. This suggests greater investment in projects like these.

9. Clean[Block]Tech

This is a growing list.

If we missed a cool project, please let us know by dropping a response below. We have several other projects we are doing due diligence on, and we will add updates. The key takeaway from this list is that each of the small projects without a patron needs your direct financial support.

So please bookmark this page, and stay tuned for news from the most optimistic, promising, and uplifting slice of crypto out there.
