Working in collaboration with concrete manufacturers and mining companies, he developed "green" chemical binders Solunexz and Glunexz for coal dust, construction aggregates, and charcoal. With continued support from Sasol, he developed Amoriguard, a non-volatile organic compound paint and skim coating based on tailings and industrial waste. Amoriguard has received Agrément certificate. In 2014, he worked on flushing solar-powered toilets that operate as a miniature waste-treatment plant. This technology based on nanofiltration and anaerobic digestion is implemented in places where water supply and sanitation are scarce. In 2016, while developing acid bricks, Doyoyo designed and manufactured Ecocast brick making machines that save water and energy, while adaptable to off-grid communities. In 2023, Doyoyo invented a "liquid cement", a type of specialty chemicals that is utilized as a replacement of Portland cement
