More feedstock avenues for Spanish biodiesel plant

A Spain-based biodiesel plant is to increase its options in terms of feedstock handling.

BDI-Bioenergy International is to retrofit the Stocks del valles facility so it can handle waste oils, including animal fats and restaurant grease.

The refit will include the installation of a new pre-esterification unit to help bolster the site’s current 9.3 million gallon capacity.

‘This new system allows for a high percentage degradation products in the oil, especially free fatty acids,’ says BDI board member Edgar Ahn. ‘In addition, it provides an efficient way for biodiesel producers to increase the profitability of their existing plants.’
