Black Lion Oil has engaged a specialist environmental consultancy firm to manage the planning and permitting process for the first UK site. Black Lion Oil has received encouraging feedback from its pre-planning application meeting with the local County Council.
Further positive meetings have been held with feedstock suppliers who are keen to supply Black Lion Oil on long-term contracts.
The Company, Black Lion Oil, is in the process of deciding on the location on its second and third sites.
Gary DeLaurentiis, CEO of GETH stated, "Black Lion Oil has been working on building their first plant for the last 8 months and has made great strides in a short period of time. We believed that Black Lion Oil could move quickly due to strategic planning and expertise in their field. BLOL has proven successful given the duration of time in which they have accomplished a significant amount of work toward this project. GETH entered into a regional development agreement with Black Lion Oil, an Irish based company whose primary focus is on emerging green technology. This agreement provides Black Lion Oil with rights to the GETH technology in defined regions to finance, install, and operate plants within a contractually allotted time."
