Nowadays, plastic wastes have become a major global issue, and one that must be addressed in order to solve the world’s resource and energy challenges. Millions of plastic items are improperly disposed of, on a daily basis, creating piles of plastic waste everywhere. This has brought serious damages to local environments around the world in terms of water, air and soil pollution. It blocks drains, pollutes rivers and wreaks havoc on the environment.



Zelij is a green tech solution that transforms plastic waste into sustainable, eco-friendly paving blocks and traditional floor tiles. Our innovative formula uses 80% plastic waste and 20% eco-friendly materials to produce 100 percent sustainable and more affordable construction materials that are three times more durable than cement and 50% cheaper to produce.

Target Beneficiaries

Zelij Invent aims to eliminate more than 3000 tons of plastic waste every year, while reducing resources used in manufacture and energy use for customers. Zelij aims to partner with gouvernment to develop its Walk Green program – creating jobs for local unemployed people building paths between isolated villages and national roads in Africa. In Morocco and worldwide this isolation issue causes lack of education and don't give access to transport, water, electricity and more for the population.

Mission and Vision

At Zelij Invet we ae on a mission to save the planet from plastic waste by providing a sustainable solution. Our vision is to track the plastic waste issue worlwide and recycle 1 Million ton of plastic by 2020. Zelij, means “little polished stone” in Arabic, embodies the essence of an Islamic art. One of our core values is to partner with local artisans to preserve the age-old heritage of Moroccan architecture, and to foster responsible business that drives social and environmental progress.
