Kabidula Investment

Upcycling quarry dust to affordable & eco-friendly housing construction blocks
2019 SEED Africa Award Finalist Biodiversity Mzuzu, Malawi

Kabidula Investment produces quarry blocks using leftover quarry dust from conventional quarry mines. The enterprise avoids the use of river sand and burnt clay bricks, as sand mining causes river siltation and river bank fall-in while burning bricks using firewood aggravates deforestation.

As eco-blocks are produced at a competitive price and quality, more environmentally-friendly and cost-conscious consumers are switching from conventional burnt bricks to eco-blocks. The growing market for quarry blocks represents an opportunity for growth in this sector.

Eco-Inclusive Impacts

Kabidula Investment has already produced 1000 eco-blocks, thereby contributing to reduced deforestation resulting from conventional brick production in its community.
  • Providing part-time employment to five people, enabling them to meet their basic household needs
  • Preparing to provide free training for block-making to ten youth groups annually

  • Producing 1000 eco-blocks, thereby contributed to reducing deforestation through conventional quarry block production
  • Implementing an outreach forest management programme targeting ten youth and women groups, resulting in an expected conservation area of five ha per year
  • Generating income of MK600,000 during the test phase by selling 1000 eco-blocks
  • Distributing MK270,000 in wages to employees
