Strategic Allies Ltd. posted this Technology Call
Seeking organisations able to help scale up production of membrane distillation systems for deployment globallyWe are working with a developer and supplier of equipment for the sustainable supply of safe drinking water in remote areas. Many remote island communities or those in conflict areas do not have access to a consistent supply of fresh drinking water or a reliable energy source to allow water to be created where it is needed. There is therefore a need for technology to transform non-potable water (polluted, waste, grey, brackish or seawater) into safe drinking water. Reverse osmosis (RO) systems are currently used in large desalination infrastructure projects, but are unsuitable when access or power is restricted, or if supply is required in a short time-frame. Membrane distillation (MD) processes are increasingly being investigated as a potential alternative to RO for these scenarios. The process relies on the partial pressure difference (triggered by a temperature difference) between each side of the vapour-selective and hydrophobic membrane pores. These pores are larger than in RO systems, resulting in less pressure, and subsequently less energy required, which facilitates the use of resulting MD systems in remote, off-grid locations with renewable energy sources.

Seeking thickening agent/s for surfactant-based systems that can be added at the end of production to increase viscosity1. The solution should be applicable to a cold process 2. Ideally a pre-dispersion or liquid would be preferred 3. The thickening agent should not cause turbidity 4. The solution/s should be compatible with anionic and cationic surfactants. 5. Please exclude bio-polymers as a solution.

Seeking Innovative Sustainable Biopolymers and Biorenewable Building BlocksSynthetic polymers are often used as thickening agents for liquid formulations. Already small quantities (< 1%) enable the formation of a gel network, which is most important for the correct application of the product. However, due to their persistence the reputation of synthetic polymers has deteriorated during the last years, which has increased the demand for natural alternatives. Despite the huge interest of the industry in green alternatives, successful candidates are a rarity, due to numerous technical and commercial hurdles. It is therefore most important to find partnerships with universities, start-ups, or well-established companies, which may lead to the development of new sustainable polymers for industrial and consumer applications.
