Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Market potential of biobased chemicals: a qualitative network analysis of adoption dynamics in South Africa’s bioeconomy

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The premise of a bioeconomy is the replacement of nonrenewable and unsustainable fossil‐derived resources and associated technologies with more sustainable alternatives. The adoption of biobased chemicals contributes toward the growth of a bioeconomy and is dependent on market and industry requirements.

Performance Evaluation of Biogas-fed Solid Oxide Fuel Cell System Coupling with CO2-selective Membrane Separator

Chemical Engineering Transactions, 2018
Biogas is an interesting fuel for hydrogen production in solid oxide fuel cell (SOFC). However, CO2 is a main composition of biogas, resulting in the dilution of hydrogen in syngas and low electrical efficiency of SOFC.

Green Innovation and Firm Efficiency: The Role of Institutional Quality in Italian High‐Tech Manufacturing Sectors

Business Strategy and the Environment, EarlyView.
ABSTRACT The aim of this research is to verify whether institutional quality affects the relationship between green innovation and firm efficiency within the high‐tech manufacturing sectors. To estimate jointly the parameters of a stochastic frontier and the coefficients of a model explaining technical inefficiency, we employed the one‐step estimation ...
