About Greyparrot

Sixty per cent of the two billion tonnes of municipal solid waste produced globally each year ends up in open dumps and landfill.

AI waste recognition startup Greyparrot provides software to monitor and sort waste at scale. The company was founded in 2019 by Mikela Druckman, Ambarish Mitra, Nikola Sivacki and Marco Paladini, and focuses on building software that can work on basic hardware that is accessible to emerging markets, where many items are sent for recycling. They have raised over £4 million worth of investment to help businesses deal with waste more sustainably.

Greyparrot believes that many of the challenges faced by the resources and waste sector can be solved through an understanding and use of composition data. Their AI allows you to make data-driven decisions about your waste.

When you’re able to monitor and analyse waste composition at scale in your sorting facility, you’ll no longer have to rely on manual spot sampling to understand the true value of your material. Digitising your waste will allow you to increase your purity and recovery rates, and prevent the mismanagement of valuable recyclables.




The Greyparrot technology is able to detect differences that are impossible to pick up with the human eye. This includes successful recognition of packaging, vs. non-packaging and food, vs. non-food grade objects, even with small and overlapping items.

They can also recognise 49+ categories of waste with +95% accuracy, even with crumpled, crushed or deformed items as well as differentiate SKU (stock keeping units) and size of products (e.g. small diet coke vs large coke).

The incredibly smart and important technology is helping companies become more sustainable and allows them to automate the manual process of sampling and auditing material.
