Special Issue Information

Dear Colleagues,

During the treatment and recycling of agro-wastes, various pollutants such as odours and GHGs, heavy metals, antibiotics and ARGs, and microplastics can have negative impact on the surrounding environment. Accumulative harmful effects can even impede sustainable agricultural production and rural development. The migration and transformation course of the nutrients and contaminants, along with potential mechanisms, should be taken into consideration, and how to comprehensively make use of diversified technologies to promote the sustainable recycling and reutilization of agro-wastes is also public concern. This Special Issue aims at disseminating information regarding sustainable and green technology concerning the recycling of agro-wastes, along with pollution reduction and control, based on the definition of mechanism and theory. For instance, research regarding in situ monitoring and measurement, composting and anaerobic digestion, land applications, high value conversion and utilization, pollution reduction and control, and other relevant topics may be involved in this Special Issue.

(1) outline the overall a. focus, b. scope and c. purpose of the Special Issue;

  1. Agro-wastes as a sustainable recycling resource in combination with pollution reduction and control.
  2. Monitoring and measurement technology, high value conversion and utilization technology, pollution reduction and control technology, etc.
  3. Disseminate sustainable and green technology of agro-wastes recycling with pollution reduction and control.

(2) suggest how the issue will usefully supplement (relate to) existing literature.

Many researchers have drawn increasing attention to the mutual interaction mechanism of different pollutants such as methane and ammonia, heavy metals and antibiotics and ARGs, and even crossover matters, simultaneously and synchronously, at the basic theoretical points. Engineers and end users have paid close attention to the efficient utilization of agro-waste, together with contamination control. The following Special Issue is in accordance with the existing literature regarding the development of sustainable trends in green agriculture.

Waste resource utilization is an important initiative in regard to promoting the development of green, low-carbon, and recycling activities in agriculture. Exploring the impact of digital social support on farmers’ waste resource utilization behavior is conducive to solving the challenges brought about by the current rapid development of the plantation industry. Based on survey data concerning 1213 farmers in Liaoning Province, this paper empirically analyzes the influence of digital social support on plantation farmers’ waste resource utilization behavior using a standard Poisson regression model and explores the roles of information comprehension and self-efficacy and the moderating role of narrow framing in the process. The results show that, firstly, digital social support had a significant positive effect on farmers’ plantation waste resource utilization behavior, and this conclusion was still valid after solving the endogenous problems. For the robustness test, every unit increase in digital social support increased the expected value of farmers’ waste resource utilization behavior by about 22.14%. Secondly, digital social support influenced farmers’ plantation waste resource utilization behavior by improving their information comprehension ability and self-efficacy. Thirdly, narrow framing will weaken the positive effect of digital social support on farmers’ plantation waste resource utilization behavior. Finally, based on the results of the heterogeneity analysis of the degree of land fragmentation and the concept of face, the influence of digital social support on the utilization of waste resources had a significant positive effect on the farmers with a low degree of land fragmentation and a strong concept of face. Therefore, the government and the agricultural sector should strengthen digital infrastructure, actively establish digital sharing platforms, and provide personalized digital social support to farmers so that they can actively engage in waste resource utilization and contribute to green and sustainable agricultural development.

The problem of the foul odor caused by H2S in livestock farms has become a major complaints. In this study, optimal sulfur-oxidizing bacteria (SOB) strains were screened from dairy farm wastewater and the adjacent soil for odor treatment. The strains and physiological functions were determined by identification and genome comparison, and the optimal operating conditions were determined by experiments under different conditions. The identification results showed that the strain that had the highest homology with Halomonas mongoliensis was Halomonas sp. AEB2. The comparative genomic results showed that the average nucleotide identity and DNA–DNA hybridization value were 95.8% and 68.6%, respectively. The optimization results were as follows: sodium succinate-carbon (10 g/L) and ammonium chloride-nitrogen (0.07 g/L). The optimal operating conditions were as follows: seeding rate 4%, temperature 30 °C, stirring speed 90 rpm, and pH 8. The oxidation products of AEB2 were mainly elemental sulfur and tetrathionate, and the metabolic pathway of AEB2 was constructed accordingly. This study suggests a feasible path to reduce H2S emissions from dairy farms, and it provides theoretical support for the restoration of livestock environment and sustainability. Full article

At present, studies on hydrophyte periphytic biofilm have mainly focused on natural water bodies or low-strength wastewater due to the inability of most plants to grow in high-strength wastewater. Therefore, the formation process and characteristics of plant periphytic biofilm growing in high-strength wastewater are still unclear. Based on the microcosm experiment, the formation process and characteristics of two kinds of plants (Myriophyllum elatinoides (Me) and Pontederia cordata (Pc)) periphytic biofilms were investigated with changes in water quality. The periphytic biofilm weight (BW) of Me and Pc reached equilibrium at 21 days, while the BW of Me was higher than that of Pc under high-load conditions (total nitrogen (TN) concentration ≥ 104.0 mg/L). When the TN concentration was 201.7 mg/L, the highest BW of Me was 0.99 mg/cm2. In addition, the structural complexity of hydrophyte periphytic biofilm was higher under TN concentrations ≥ 70.9 mg/L than that under TN concentrations ≤ 56.9 mg/L. N concentration and environmental factors could affect periphytic BW and biofilm Chlorophyll a (Chla.). Through linear regression fitting, it was found that periphytic BW and biofilm Chla. were positively correlated with the concentrations of NH4+-N and TN in water, while they were negatively correlated with the concentration of NO3-N. Random Forest results showed that NO3-N concentration had an important effect on hydrophyte periphytic BW. The results of this study provided a new understanding of the formation process and characteristics of aquatic plant periphytic biofilm under high-strength conditions and a prospect for sustainable development in the treatment of high-strength wastewater.
