Hi,

I am currently designing a large storage tank to hold 9400 Litres of Biomass. I need a material that can withhold that force, withstand bio/chemical attack without any sign of decay for 20 years +. I am undecided about what manufacturing method to design this tank for. What are the limitations of rotational moulding for a tank that is approx 2m cubed? I am worried about cooling issues that could affect its strength. Aesthetics aren't an issue as this tank will be concealed. Performance is key.

I look forward to your replies

Regards

Sam Morey
