Enabling Production of Algal Biofuels by Techno-Economic Optimization of Co-Product Suites

Frontiers in Chemical Engineering, 2022
Recent techno-economic analysis (TEA) has underscored that for algal biofuels to be cost competitive with petroleum fuels, co-products are necessary to offset the cost of fuel production.

Sourcing thermotolerant poly(ethylene terephthalate) hydrolase scaffolds from natural diversity

Nature Communications, 2022
Enzymes have potential for recycling plastics such as PET, a polyester used in textiles and single-use packaging. Here, the authors identify and characterize additional PET-active biocatalysts and expand the number and diversity of thermotolerant ...

Volatile Fatty Acid Recovery from Arrested Anaerobic Digestion for the Production of Sustainable Aviation Fuel: A Review

Fermentation, 2023
The process of producing sustainable aviation fuel (SAF) from organic waste involves the use of volatile fatty acids (VFAs) as intermediates that are obtained via arrested anaerobic digestion (AAD) and VFA recovery.

Continued results from a field campaign of wake steering applied at a commercial wind farm – Part 2 [PDF]

Wind Energy Science, 2020
This paper presents the results of a field campaign investigating the performance of wake steering applied at a section of a commercial wind farm. It is the second phase of the study for which the first phase was reported in Fleming et al. (2019).

Catalytic carbon–carbon bond cleavage in lignin via manganese–zirconium-mediated autoxidation

Nature Communications
Efforts to produce aromatic monomers through catalytic lignin depolymerization have historically focused on aryl–ether bond cleavage. A large fraction of aromatic monomers in lignin, however, are linked by various carbon–carbon (C–C) bonds that are more ...

Initial results from a field campaign of wake steering applied at a commercial wind farm – Part 1 [PDF]

Wind Energy Science, 2019
Wake steering is a form of wind farm control in which turbines use yaw offsets to affect wakes in order to yield an increase in total energy production.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Natural diversity screening, assay development, and characterization of nylon-6 enzymatic depolymerization

Nature Communications
Successes in biocatalytic polyester recycling have raised the possibility of deconstructing alternative polymers enzymatically, with polyamide (PA) being a logical target due to the array of amide-cleaving enzymes present in nature.

Valorization of Anaerobic-Fermentation Liquid Digestates—Membrane-Based Process Development

Membranes, 2023
Complete valorization of various wastes and effluents, with significant organic content, remains a great challenge in the pursuit of a circular economy. The approach based on anaerobic fermentation, leading to valuable biogas production, has been broadly
