Circular Economy Pathways for Airport Climate Change Mitigation
Business Strategy and the Environment, EarlyView.ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

Synthesis of palm oil based polyol via glycerolysis and transamidation reactions for polyurethane foam production [PDF]
, 2014 Renewable sources like vegetable oil have been used to prepare many polymeric resins due to the awareness on environmental issue and depletion on petrochemical sources. In polyurethane (PU) production, petroleum-based polyols such as polypropylene glycol

TRANSESTERIFICATION OF VEGETABLES OIL USING SUBAND SUPERCRITICAL METHANOL
Reaktor, 2012 A benign process, non catalytic transesterification in sub and supercritical methanol method was usedto prepare biodiesel from vegetables oil. The experiment was carried out in batch type reactor (8.8 mlcapacity, stainless steel, AKICO, JAPAN) by changing the reaction condition such as reactiontemperature (from 210°C in subcritical condition to 290°C ...

Framing Modern Slavery: Do Stakeholders Talk Past Each Other?
Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.ABSTRACT Modern slavery literature has thus far mostly adopted a downstream perspective, in the sense that researchers investigated corporate actors' responses after the enactment of transparency legislation. The common finding is that corporate disclosure is poor and ineffective, contributing to a failure to eradicate modern slavery.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
