Biodegradable Polyesteramide Films for Pervaporative Dehydration of Isopropanol–Water

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Polyesteramides are biodegradable polymers possessing good mechanical properties with potential applicability in membrane separations. In this work, polymer films from ε‐caprolactam and ε‐caprolactone‐based polyesteramides were prepared at a ratio of monomer units set so that the resulting copolymer had a low crystalline phase content.

Molecular techniques to characterize the invA genes of Salmonella spp. for pathogen inactivation study in composting [PDF]

arXiv, 2014
The relatively low concentration of pathogen indicators, such Salmonella, in composting sometimes causes a problem with detection when using the conventional techniques. The presence of viable but non-culturable (VBNC) organisms is also a potential problem with Salmonella detection when using conventional techniques.

Waste Management and Waste Disposal Detected by Combination of Analytical Methods: Late Bronze Age Březnice Settlement Site (South Bohemia)

Archaeological Prospection, EarlyView.
ABSTRACT Waste disposal processes and landfill management are crucial subjects in the field of settlement archaeology. Our study is focused on understanding the processes that are connected to the formation of the infills of settlement features and the recycling of the building materials (daub and wood) and waste management.

The Process and Pathogen Behavior in Composting: A Review [PDF]

arXiv, 2014
Composting is defined as the biological decomposition and stabilization of organic substrates under aerobic conditions to allow the development of thermophilic temperatures. This thermophilic temperature is a result of biologically produced heat. Composting produces the final product which is sufficiently stable for storage and application to land ...

Briquettes Compost and Liquid Fertilizer Application for Yellow Local Rice Growing on Bamboo Rafts as Floating System

Sains Tanah: Journal of Soil Science and Agroclimatology, 2017
Growing rice had been done previously by applying crumble compost on the floating raft but part of compost was lost through runoff, so briquettes compost needs to be buried in soil.

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...

Combining dynamic life cycle assessment and net ecosystem exchange through the framework of biobased materials and products‐life cycle assessment (BBM‐LCA): application to polylactic acid

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biobased products can achieve carbon negativity by storing biogenic carbon in the technosphere through circular loops. Quantifying these benefits requires quantitative assessment tools such as life cycle assessment (LCA). However, the LCA of biobased materials is not straightforward due to the complexity of addressing agroecosystem carbon ...

Biochar‐based fertilizers increase crop yields in acidic tropical soils

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Depletion of soil organic carbon and nutrients creates mounting challenges for agricultural production in tropical regions, putting livelihoods and food security at risk. Biochar‐based fertilizer (BBF) has been suggested as a tool to maintain yields while concurrently improving soil organic carbon content and related soil functions. This study
