Innovative Toilet and Shower Systems as a SolutionInnovative toilet and shower systems can help relieve the burden on wastewater treatment plants. Water-saving toilet flushes, greywater usage systems, and advanced shower heads are a few technologies that can help reduce water consumption and improve wastewater quality.
Heterotrophic bacteria such as Cupriavidus necator can already produce PHB bioplastic. These bacteria's energy source is the sugar obtained from crops. Cyanobacteria has a significant advantage in PHB production. To conclude, microalgae can fix sunlight and extract energy from it. As a result, PHB production is CO2-neutral. Indeed, it offers ethical and ecological advantages over using heterotrophic bacteria.PHB production by cyanobacteria is currently still in primary research mode. It could be years before it is ready for industrial utilisation. Last but not least, there is also the question of price. PHB production by heterotrophic bacteria is currently more cost-effective.
