Paper Abstract:
|
The environmental impact of the production of condensed tannins from acacia bark was investigated from gate-to-gate perspective. Of the six process steps in the production system that were assessed, the spray drying and adsorption (purification) steps were identified as the main sources of the environmental impact of the whole system. This is due to intensive consumption of energy and consumption of makeup ethanol, respectively. The most important action to improve the environmental performance of the system is to reduce water consumption in the extraction, as it will reduce energy demand in the spray drying step. This LCA shows the most important steps to facilitate process development towards lower environmental impact. |
