Product description

Plastic-sand Composite Pavers by Gjenge Makers offer a groundbreaking solution to the dual challenges of plastic waste pollution and sustainable urban development. By blending shredded plastic waste with sand and utilizing proprietary machinery, these composite pavers are not only environmentally friendly but also highly durable and versatile.

The innovative production process involves heating and compressing the plastic-sand mixture to create lightweight yet robust pavers suitable for various applications. The fibrous plastic structure provides exceptional compression strength, surpassing traditional concrete blocks. With a range of colors and formats available, from heavy-duty for vehicular traffic to light-duty for pedestrian areas, these pavers cater to diverse urban design needs.

What sets Gjenge Makers' solution apart is its self-sustaining and low-maintenance production process. By using locally-sourced plastic waste and efficient machinery, the company can produce up to 1,500 blocks per day, contributing to both environmental conservation and economic sustainability.

These composite pavers not only divert plastic from landfills but also offer cost-effectiveness, color customization, and long-term durability. They are particularly well-suited for sustainable urban development projects in African communities and beyond, where the need for eco-friendly building materials is paramount.
