Raghava Dasarathy

Raghava Dasarathy has been Anellotech’s Senior Vice President of Research, Development and Engineering since April 2024. He joined the Company in 2013. As Director of Engineering he worked on process design, improvement, commercialization, and techno-economic evaluation of both Bio-TCat and Plas-TCat. Raghava served as technical lead/coordinator for the design, fabrication, and installation of the first-of-its-kind TCat-8 Demo plant in Silsbee, Texas. For Bio-TCat, from 2016-2019, Raghava served as lead for the on-site TCat-8 operations team of Anellotech and IFPEN engineers. He led the team’s efforts beginning with the commissioning of the TCat-8 plant including troubleshooting and unit modifications leading to successful sustained (7,500 hours) performance testing. Culmination of this effort was generation of the necessary data to develop the commercial plant design and process economics. Raghava then served as technical coordinator for Anellotech during the commercial design phase with IFPEN and Axens as well as the leading the effort on process/plant economic analysis and value engineering for the Bio-TCat technology.

For the now on-going Plas-TCat technology development, Raghava worked on conceptual design and developed the Plas-TCat process economic model. He also worked on modifying the TCat-8 unit for Plas-TCat operation, as well as upgrading equipment to improve safety, reliability, and performance as well as co-managing TCat-8 staffing and operations for the Plas-TCat campaign.

Today, Raghava leads the entire Plas-TCat development program, and coordinates technical activities with our partners Technip Energies and R Plus Japan.

Raghava started his career at a global EPC firm where he worked chemical and petrochemical plant design for several, international, large-scale projects.

Raghava then moved into environmental project engineering (catalytic reduction of NOx/Sox) for gas-fired power plants.  Raghava has a B.S. in Chemical Engineering from Georgia Tech and an M.S. from University of Alabama-Huntsville.

Leslaw Mleczko

From 1996 to 2012 Prof. Dr. Leslaw Mleczko worked as a senior scientist and then research manager for Bayer AG Central Research, as well as Corporate Engineering and Technology. For more than decade he headed the Competence Center “Reaction Engineering and Catalysis” and led development of several catalytic processes with special focus on sustainability, e.g. by using biomass or CO2 as feedstock for chemical conversions. From 2012, until his retirement in 2020 he was a V.P. for Process Technology and a Distinguished Fellow. Leslaw supported and steered international projects and programs aiming at development of novel technologies, often in collaboration with start-up companies. He began his professional career as a research engineer in the Institute for Fuel Energy where he participated in the development of the multistage fluidized-bed technology for coal gasification. After obtaining his PhD from the Silesian Technical University (Poland) and completing a post-doc in fluidization and applied catalysis at the Institute of Technical Chemistry (University of Hannover), Leslaw lead research on catalytic conversion of natural gas at the Catalytic Reaction Engineering Group in the Chair of Technical Chemistry of the Ruhr-University Bochum where he became a faculty member. Prof. Dr. Mleczko has coauthored more than 100 patents and 100 peer reviewed publications.

Jean-Pierre Burzynski

Prior to Anellotech, Jean-Pierre served as Director of the Process Business Unit at IFP Energies nouvelles (IFPEN), which is a major research and innovation center in the fields of energy, transport and the environment; he holds advanced degrees in chemistry and fluid dynamics. He drove research and innovation efforts in areas such as petrochemicals, natural gas conversion, biofuels, bioproducts and plastic recycling. During his tenure at IFPEN, he was responsible for the development of many processes related to renewable fuels and bioproducts (many commercialized, licensed and implemented in various industries).
