Our core business is wastewater biorefineries: creating valuable commodity products from wastewaters and complementary solid wastes. As a market segment, however, this is not viable yet. So, while we move this into reality...


our core business is holistic wastewater management.


We focus on:

  • Biological treatment, specifically through using bacteria and wetlands (we call the wetlands macrophyte bioreactors);
  • Appropriate scale solutions, but our preference is for smaller, modular, decentralised systems, from rural solutions, peri-urban applications to household waste, ornamental fishponds, aquaculture, stormwater canals, water sensitive urban design, to corporate greenspace management;
  • Applying large scale engineered treatment systems thinking through a biomimicry design, smaller scale lens, to bring you the best of both.

We are improving our knowledge in the following areas, and can assist you here with advice, guidance and ideas, but please note, these are not our expert areas (yet):

  • Fungal bioremediation;
  • Algal production;
  • Biogas production;
  • Solar PV and solar thermal applications;
  • Process control, analysis and monitoring, using FLOSS (free libre open sourse software/systems) thinking.



Globally, we are moving more towards a bioeconomy, or bio-based economy. Biological processes fundamentally happen in water, and as such this global move is impacting water use significantly. We have identified wastewater as the most critical bottleneck in making a bioeconomy function sustainably, and thus we are working towards turning wastewater into an opportunity.


Supplementing other technology based processes that focus on a specific product or technology using wastewater, we look at the engineering behind what is required to make this bioproduction happen. We've named this concept 'wastewater biorefineries'. As such, we work as consulting partners with existing technologies and companies to make the concept of a circular economy a reality.


Back home, we have identified two additional challenges: the poor public perception of waste and science, and a lack of appropriate process control and analysis tools. Merah Mas addresses these challenges through two developments: Adventure Sport & Science Tourism (ASST, or IndieBio Events) and ShackLabs.
