Pilot-scale study of innovative mechanically-enhanced dynamic composting for treating kitchen waste.

This study introduced a novel mechanically-enhanced dynamic composting (MEDC) method for treating kitchen waste (KW) through partial-mixing and stratified fermentation. A pilot test varied aeration frequencies (AF) to refine control parameters and explore the maturation mechanism. Results showed that a moderate AF (10 min/4 h) achieved optimal efficiency, with a compost germination index of 123 % within 15 d.

Carbohydrate degradation contributes to the main bioheat generation during kitchen waste biodrying process: A pilot study.

Biodrying is a promising method for processing kitchen waste (KW) with high moisture content into reusable solid recovered fuels (SRFs). During biodrying, a large amount of bioheat generated from biodegradation of biochemical components results in KW dehydration. However, the degradation rules of these components and their contribution to the bioheat in KW biodrying have not been systematically clarified.

Garbage source classification performance, impact factor, and management strategy in rural areas of China: A case study in Hangzhou.

Garbage classification and reduction is imperative in many developing countries, where the imbalance between the rapid growth of solid waste and insufficient disposal capacity can be challenging. In order to evaluate whether a novel '2 + T' source classification method (biodegradable waste, other waste, and toxic waste) and three types of source classification and resourcing treatment patterns implemented in the rural areas of Hangzhou can be widely applied, field investigations, questionnaire interviews, and factor analysis were carried out comprehensively. By means of '2 + T' source classification method, biodegradable waste, accounting for the largest proportion of rural domestic waste, can be effectively separated for the subsequent reduction and resource treatment.

Improving methane yield from organic fraction of municipal solid waste (OFMSW) with magnetic rice-straw biochar.

Magnetic biochar is a potential economical anaerobic digestion (AD) additive. To better understand the possible role of magnetic biochar for the improvement of biomethanization performance and the retention of methanogens, magnetic biochar fabricated under different precursor concentrations were introduced into organic fraction of municipal solid waste (OFMSW) slurry AD system. Results showed that methane production in AD treatment with magnetic biochar fabricated under 3.

Metagenomic analysis of microbial consortia enriched from compost: new insights into the role of Actinobacteria in lignocellulose decomposition.

Background: Compost habitats sustain a vast ensemble of microbes specializing in the degradation of lignocellulosic plant materials and are thus important both for their roles in the global carbon cycle and as potential sources of biochemical catalysts for advanced biofuels production. Studies have revealed substantial diversity in compost microbiomes, yet how this diversity relates to functions and even to the genes encoding lignocellulolytic enzymes remains obscure. Here, we used a metagenomic analysis of the rice straw-adapted (RSA) microbial consortia enriched from compost ecosystems to decipher the systematic and functional contexts within such a distinctive microbiome.

[Synthesis of benzothiazole derivatives and their binding characteristics with beta-amyloid].

Alzheimer's disease (AD) is a progressive neurodegenerative disease endangering human health seriously. Recent reports have revealed that beta-amyloid aggregates play a key role in the pathogenesis of AD. Thus, targeting the Abeta plaques benzothiazole derivatives were synthesized with the scaffold of the most promising imaging agent PIB ([11C]-6-OH-BTA-1, [11C]-2-(4-(methylamino)phenyl)-6-hydroxybenzothiazole) and C = N as linker to study the binding characteristics with the target protein through surface plasmon resonance (SPR) technique.
