Quasar ScienceTech is a technology-based and science & technology consulting company focusing on advanced clean technology and materials developments, science and technology assessments and technical due diligence. The company was established in response to global environmental challenges and the need for scientific evaluations of new technologies and advanced materials applications. We provide science and technology assessments and technical due-diligence using a multidisciplinary approach and producing new ideas and concepts to initiate “out of the box” views and deliver optimal solutions to complex technological and environmental issues for our clients. Currently, we develop an advanced waste conversion technology based on a cost-effective chemical recycling process, which is most suitable for contaminated and mixed waste (e.g., MSW, plastic, biomass, industrial and medical waste) recycling into high-value sustainable products, such as hydrogen, electricity, liquid synthetic fuels, and chemicals. Waste recycling into hydrogen could become a base of the hydrogen and circular economy. Having a comprehensive background and wide-range of knowledge of different sciences and technologies, we provide multidisciplinary science and technology consulting in the fields of Clean Technology & Energy, Materials Science, Chemistry, Environmental Science, and Advanced Materials Applications. We conduct an in-depth critical review and verification of the proposed technology and advanced materials applications. We offer expertise to government and education institutions and companies involved in investments, R&D, manufacturing, legal cases, and education to help them identify problems and solutions in their work.
