TL;DR: In this article, the state of the art of technologies and assessment methods on economic performance, safety, health and environment (SHE) as well as social impact for biofuel production are reviewed.

TL;DR: In this work, two different IPWI schemes, that is, “direct” and “indirect” integration are analyzed using mathematical optimization techniques and a mixed integer linear program (MILP) model is formulated and solved to achieve a globally optimal solution.

TL;DR: In this article, a pinch targeting approach is presented to locate the minimum CO2-neutral and low-carbon sources for energy sector planning, and a novel automated targeting approach to determine the optimum allocation of energy sources in a segregate planning scenario where energy targets for different sub-sectors in the planning horizon are located.

TL;DR: In this paper, a graphical pinch-based methodology for planning retrofits for carbon capture and storage (CCS) in the power generation sector is presented, which is used to determine the minimum extent of CCS retrofit that meets the sectoral carbon footprint targets.

TL;DR: The proposed automated targeting technique is extended to determine the targets for RCNs with interception placement to identify minimum fresh resource flow rate/cost targets in a resource conservation network (RCN) with material reuse/recycle.
