Accounting for Substitution: Improving Estimates of GHG Reductions From Cattle‐Based Product Demand Shifts

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Estimates of reductions in greenhouse gas (GHG) emissions from lower demand for cattle‐based products must account for substitution effects. This study collected data through two surveys—one on ground beef and another on dairy milk—to evaluate substitution effects and potential GHG reductions.

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, EarlyView.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

3D-printed NiZr0.1/SiOC monolithic catalysts with synergistic Zr doping for enhanced low-temperature CO2 methanation: dual-pathway mechanism and structural stability

Fuel Processing Technology
Monolithic NiZr0.1/SiOC catalysts with tailored architectures were fabricated via direct ink writing (DIW) 3D printing for CO2 methanation. Zr doping markedly enhanced low-temperature activity (

Nickel@Siloxene catalytic nanosheets for high-performance CO2 methanation

Nature Communications, 2019
Two-dimensional (2D) materials are of considerable interest for catalyzing the heterogeneous conversion of CO2 to synthetic fuels. In this regard, 2D siloxene nanosheets, have escaped thorough exploration, despite being composed of earth-abundant ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Coupling Electrochemical CO2 Reduction With Ethanol Oxidation for Acetate Production in a Dual‐Electrolyzer System

Angewandte Chemie, EarlyView.
A tandem cell system coupling electrochemical CO2 reduction and electrochemical ethanol oxidation is demonstrated for overall acetate production, providing concepts for a CO2‐negative bioethanol to acetate pathway. ABSTRACT Bioethanol production from biomass is suggested as a strategy for greener fuel production.

Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices

Agribusiness, EarlyView.
ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

CO2 Methanation: Thermodynamic Simulations for Enhanced Methane Production and Hydrogen Source Evaluation

Chemical Engineering Transactions
Carbon dioxide (CO2) methanation has emerged as a powerful tool, allowing CO2-rich gas utilization to generate value-added products, such as methane (CH4), which can be used as a fuel and chemicals.

Metal-promoted mesoporous ZSM5 for CO methanation to produce synthetic natural gas (SNG) [PDF]

, 2014
In recent years, enormous emissions of carbon oxide (CO and CO2) by combustion of fossil and fuel have contributed to the increase in global temperatures and climate changes due to the ‘greenhouse effect’ [1].

Bioelectrochemical methane production from CO2

Nowadays, most of our energy and fuels are produced from fossil resources. Fossil resources are, however, finite and their use results in emissions that affect the environment and human health. For reasons of energy security and environmental sustainability, there is therefore a need to produce energy and fuels from renewable resources.
