To produce renewable petroleum in big scale factory the material bio-resistant and impermeable with respect the working bacteria is necessary. I suggest using High-Energy Mixed (HEM) concrete I work with last 20 years. Conventional concrete with pores and capillaries doesn't fit this purpose. Polymer concrete is denser, but is not bio-resistant. Only HEM concrete where pores and capillaries are filled with its own CSH gel non-permeable and bio-resistant. I use the same ingredients - cement, sand, water and high speed mixing. See www.hemconcrete.com.
