Maleic Acid-Butanol Pretreatment to Enhance Cellulose Accessibility for Enzymatic Hydrolysis and Ethanol Production from Oil Palm Empty Fruit Bunch.
ACS Environ Au

Department of Chemical Science and Engineering, Graduate School of Engineering, Kobe University, 1-1 Rokkodaicho, Nada-Ku, Kobe 657-8501, Japan.
Pretreatment of lignocellulosic biomass is crucial yet challenging for sustainable energy production. This study focuses on enhancing enzymatic accessibility of cellulose in oil palm empty fruit bunches by optimizing pretreatment parameters to improve glucose and ethanol yields while reducing fermentation inhibitors. It evaluates the impact of maleic acid concentrations on biorefinery processes.

The analysis of mineral oil aromatic hydrocarbons (MOAH) in vegetable oils is currently associated with high uncertainty due to various factors ranging from sample preparation to data interpretation. One significant factor is the coelution of biogenic compounds of terpenic origin with the MOAH fraction during chromatographic analysis. The common purification method is epoxidation, a chemical reaction that changes the polarity of the interferences, allowing their separation from MOAH.

Department of Plant Protection, IPB University, Bogor, Indonesia.
Smallholder farmers produce over 40% of global palm oil, the world's most traded and controversial vegetable oil. Awareness of the effects of palm oil production on ecosystems and human communities has increased drastically in recent years, with ever louder calls for the private and public sector to develop programs to support sustainable cultivation by smallholder farmers. To effectively influence smallholder practices and ensure positive social outcomes, such schemes must consider the variety in perspectives of farmers and align with their priorities.

School of Chemistry, Chemical Engineering and Biotechnology, Nanyang Technological University, 62 Nanyang Drive, Singapore, 637459, Singapore.
A series of biomass-based linear aliphatic polyesters are synthesized by combining sebacic acid (SA) (C10 diacid) and 1,18-octadecanedioic acid (OA) (C18 diacid) with a series of diols with varied alkyl chain lengths (C2 to C10 diols). SA and OA are obtainable from castor oil and palm oil, respectively. The reaction extent (polymerization extent) is high (≥96%) in all cases, and the number-average molecular weight (M) is 10 000-43 000 g mol after purification.

Sarawak Tropical Peat Research Institute, Kota Samarahan, Malaysia.
Tropical peatlands are significant sources of methane (CH₄), but their contribution to the global CH₄ budget remains poorly quantified due to the lack of long-term, continuous and high-frequency flux measurements. To address this gap, we measured net ecosystem CH exchange (NEE-CH) using eddy covariance technique throughout the conversion of a tropical peat swamp forest to an oil palm plantation. This encompassed the periods before, during and after conversion periods from 2014 to 2020, during which substantial environmental shifts were observed.
