Technical Solutions

The intensifi cation of agricultural production has led to the disruption of nutrient cycles in agroecosystems. In livestock farming, one of the key problems is the low degree of using secondary resources (organic fertilizers based on manure and manure). (Research purpose) To substantiate the basic principles of assessing the agroecosystem environmental sustainability and to develop engineering methods for ensuring environmental safety in livestock farming. (Materials and methods) To solve the problems of agroecological assessment, eff ective technology choice and intelligent system creation, the following indicators were used: 1. specifi c density of animals (mainly for macro-assessment); 2. nutrient balance (the diff erence in the amount of nitrogen available in the formed organic fertilizers with environmentally safe consumption); 3. nitrogen losses during the disposal of organic waste from livestock farming; 4.the eff ectiveness of implementing the best available techniques (BAT). (Results and discussion) Using the assessment of indicators 1 and 2 in the case of the Leningrad region, it was revealed that 3 districts are classifi ed as territories with an excessive risk to the environment, 1 district is classifi ed as a territory with a high risk, 5 districts – with an acceptable risk, and 8 districts – with a low risk to the environment. To solve problems in areas with excessive and high load, we conducted an assessment on indicators 3 and 4, which allowed us to explore technical solutions and select the BAT to reduce the environmental burden. The obtained results showed that among the main technical solutions in the fi eld of organic waste management of livestock farming are biofermentation and the introduction of liquid organic fertilizers. Biofermentation in special chambers can reduce emissions of polluting gases by more than 2 times, and speed up the processing process by more than 60 times. To work with liquid organic fertilizers, intelligent machines with low-emission working bodies have been developed to reduce nitrogen losses during application by up to 50 percent. To solve the problems of agricultural monitoring and engineering solution management, a digital system has been developed that allows to model scenarios of technological development and their impact on the agroecosystem environmental sustainability. (Conclusions) The results obtained allow us to systematically analyze the problems of agroecosystem environmental sustainability and propose specifi c technical and optimization solutions for livestock farming.

In the Northwestern Federal District, the main agricultural source of environmental pollution is the disposal of organic waste (manure and litter), which accounts for a risk of 85 percent. The problem of ensuring environmental safety requires appropriate solutions based on modern intelligent machine technologies, means of monitoring and controlling technological processes of organic waste disposal. (Research purpose) To provide rationale for combined methods of solving environmental problems in animal and poultry farming. (Materials and methods) The authors studied the environmental impact of machine technologies used in livestock and poultry farming. The studies were carried out by assessing environmental risks and the sustainability of agroecosystems, applying methods and techniques for assessing the best available technologies, and studying the main prospects of developing intelligent digital technologies. (Results and discussion) The authors have identified the main methods of solving the environmental problems associated with large farm enterprises, including the calculation, design and system operation of the best available technologies for agricultural production. They have proposed a technical tool in the form of a bioreactor for the disposal of organic waste, capable of reducing manure and litter processing period in 60 times and providing automated flow and process control with online registration of production and environmental indicators. They have described an intelligent system for monitoring and utilizing organic waste, including a conceptual framework for establishing modular centers for deep processing. (Conclusions) The authors have proved that the implementation of modern methods for ensuring effective and environmentally safe agricultural production requires the establishing of experimental plot sites for complex research and demonstration of a “machine technology – monitoring – management” system. It has been proposed that a site of the VIM agrobiotechnological cluster should be established at a pilot livestock complex enterprise in the Leningrad Region. The authors have identified promising areas of research to ensure the transition of agricultural production to a new technological structure that implements the principles of Smart Farming to provide for the disposal of at least 510 million tons of agricultural organic waste a year.

Partners in the implementation of Community Service is the Kembang Lestari Peasant Women's Group located in Taman Village, Abian Semal Subdistrict, Badung Regency.  This group has problems with the high price of chemical fertilizers and vegetable pesticides for the treatment of cultivated crops.  This condition causes an increase in production costs and decreased profits. They have yet to find a solution to get cheaper, environmentally friendly plant-based fertilizers and pesticides that they will use in their organic farms in the future.   Therefore, it is necessary to provide an alternative to organic fertilizers while serving as vegetable pesticides that are easy to make, cheap, and environmentally friendly.  The alternative is an eco-enzyme that can be made from organic waste in the form of fruit peels. Eco-enzymes have the same benefits as liquid fertilizers, compost, anti-bacterial, midges, and disinfectants. Women's Farmer Groups of Kembang Lestari are given knowledge of eco-enzymes and their benefits, how to make and how to apply them to plants.  The methods carried out in the implementation of this activity are by interviewing, face-to-face, counseling, and practice methods directly. First, the authors held general counseling on what an eco-enzyme is, its benefits for plants, and environmental sustainability. Second, the authors provide hands-on training in the manufacture of eco-enzymes and how to implement them and conduct several evaluations to ensure farmers can make eco-enzymes independently and see what percentage of the increased production and increased profits earned by the farmer group after the implementation of these eco-enzymes.   Third, it motivates farmers to keep using eco-enzyme fertilizers continuously in cultivating crops.

Abstract Organic waste from agricultural production, bedding manure of cattle, pigs, sheep, horses, chickens and poultry litter when kept in cages are the main components for the production of organic fertilizers and biogas production. Waste of grain, cereal crops and sugar beets should be used as components for reducing moisture during aeration in piles, houses and bioreactors. Fresh organic waste should be stored on the sites in piles, where, before being processed in aeration houses and bioreactors, they must go through a mesophilic period. Fresh organic waste, when introduced into the soil in the first year, negatively affects the growth and development of plants, therefore, it must be disinfected and processed into organic fertilizers and biogas. Currently, the lack of knowledge about the methods of disinfection and processing of agricultural waste requires the development of new technological and technical solutions.

Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.

The present study develops a multi-step methodology for identification and quantification of microplastics and micro-bioplastics (together called in the current work micro-(bio)plastics) in sludge. In previous studies, different methods for the extraction of microplastics were devised for traditional plastics, while the current research tested the methodology on starch-based micro-bioplastics of 0.1–2 mm size. Compostable bioplastics are expected to enter the anaerobic or aerobic biological treatments that lead to end-products applicable in agriculture; some critical conditions of treatments (e.g. low temperature and moisture) can slow down the degradation process and be responsible for the presence of microplastics in the end-product. The methodology consists of an initial oxidation step, with hydrogen peroxide 35% concentrated to clear the sludge and remove the organic fraction, followed by a combination of flotation with sodium chloride and observation of the residues under a fluorescence microscope using a green filter. The workflow revealed an efficacy of removal from 94% to 100% and from 92% to 96% for plastic fragments, 0.5–2 mm and 0.1–0.5 mm size, respectively. The methodology was then applied to samples of food waste pulp harvested after a shredding pre-treatment in an anaerobic digestion (AD) plant in Italy, where polyethylene, starch-based Mater-Bi® and cellophane microplastics were recovered in amounts of 9 ± 1.3/10 g <2 mm and 4.8 ± 1.2/10 g ⩾2 mm. The study highlights the need to lower the threshold size for the quantification of plastics in organic fertilizers, which is currently set by legislations at 2 mm, by improving the background knowledge about the fate of the micro-(bio)plastics in biological treatments for the organic waste.

Развитие органического земледелия, в первую очередь, зависит от наличия органических удобрений и биопрепаратов. Цель исследований – на основе утилизации органических отходов и сырья разработать полифункциональные биопрепараты из компонентов животного и растительного происхождения и изучить их влияние на показатели агрофитоценозов и урожайность полевых и садовых культур. В работе использованы результаты исследований по разработке полифункциональных биопрепаратов, а также их эффективности на опытном поле Самарского ГАУ в 2017-2019 гг. В результате была разработана ассортиментная линейка биопрепаратов «АгроТоник» с функциями удобрения и биостимулятора роста: «Цветовод», «Садовод», «Овощевод», «Полевод», «Лесовод» и «Универсальный». «АгроТоник», в отличие от многих органических и минеральных удобрений, содержит все необходимые для растений компоненты: макро-, мезо- и микроэлементы в легкодоступной форме, микроорганизмы, стимуляторы роста – биоактивные фитогормоны, аминокислоты растительного происхождения, витамины, комплекс целлюлозолитических ферментов, почвенные антибиотики, гуминовые вещества, биоприлипатель. Многокомпонентный биопрепарат с функциями удобрения, фунгицида и бактерицида снижал пораженность растений озимой пшеницы на 16,7-27,1 %, по отношению к контролю, и на 17,4-22,6 %, по сравнению с минеральными удобрениями. Биопрепарат повышал урожайность озимой пшеницы на 7,7-25,4 % по сравнению с контролем, тогда как применение пестицида только на 5,3-11,5 %, при стоимости однократно внесенного гербицида в среднем 500,00 руб./га, а биопрепарата – 300,00 руб./га при двукратной обработке. The development of organic farming primarily depends on the availability of organic fertilizers and biological products. The goal of the research is to develop multifunctional biological products from components of animal and plant origin based on the utilization of organic waste and raw materials and to study their impact on the indicators of agrophytocenoses and the yield of field and horticultural crops. The work uses the results of research on the development of multifunctional biological products, as well as their effectiveness in the experimental field of the Samara State Agrarian University in 2017-2019. As a result, the line of "AgroTonik" biological products with the functions of fertilizer and the growth biostimulator was developed: «Tsvetovod», «Sadovod», «Ovoshchevod», «Polevod», «Lesovod» and «Universal'niy». "AgroTonik", unlike many organic and mineral fertilizers, contains all the components necessary for plants: macro -, meso- and microelements in an easily available form, microorganisms, growth stimulators – bioactive phytohormones, amino acids of plant origin, vitamins, a complex of cellulosolytic enzymes, soil antibiotics, humic substances, bio-sticking agent. The multicomponent biological product with the functions of fertilizer, fungicide and bactericide reduced the affection of winter wheat plants by 16.7-27.1 % concerning the control, and by 17.4-22.6 %, in comparison with mineral fertilizers. The biological product increased the yield of winter wheat by 7.7-25.4% compared to the control, while the use of a pesticide only by 5.3-11.5 %, with the cost of a single herbicide on average 500 rubles/ha, and a biological product – 300 rubles/ha with double treatment.

Tackle Climate Change

Reduction in emissions is the key to tackle climate change issues and achieve environmental sustainability. The Gulf Cooperation Council member countries however, not only generate the highest quantity of MSW/capita when compared globally but also in most of these countries such waste is just dumped at different landfill stations. In Oman, the total quantity of MSW stood at 2.0 million tonnes/year. The emission from this waste is estimated at 2,989,467 tonnes/year (CO2 Equivalent). This article attempts to develop frameworks that considered landfilling, composting, and recycling of MSW and compared the emissions of these frameworks. The framework (F2) which proposes the landfilling and composting process for the organic waste which normally goes to landfills results in an increase of emissions by 7% as compared to landfill practice. Similarly, the samples of MSW collected in Oman show a good amount of recycling waste. The framework (F3) which considers the landfill, composting, and recycling reduced the total Greenhouse Gas emissions from 2,989,467 tonnes/year to 2,959,735 tonnes/year (CO2 Equivalent); representing a total reduction of 1% in emissions. Although composting increases the emissions, however, considering composting and recycling will not only reduce the burden on landfills but will promote agricultural and industrial activates.

Nutritional Benefits

Numerous studies have shown that replacing a portion of beef with plant-based foods in daily diets of high-income nations can improve health, nutrition, and environmental consequences globally. Pulses are one of the major plant-based protein foods shown to have both environmental and nutritional benefits. For consumers to adopt more plant-based foods in their diets, more options are needed that meet consumer demands for taste, convenience, nutrition, and sustainability along with dietary preferences. Beef-based burger patties can be made more sustainably, nutritiously, and cost-effectively while maintaining palatability by reformulating with a portion of pulses such as whole cooked lentils. The aim of this study was to quantify the nutritional and environmental benefits of such lentil-reformulated beef burgers. Here we compared the nutrient balance score (considering 27 essential macro and micronutrients) and environmental footprints (carbon, bluewater, water scarcity, land use, and biodiversity) of an all-beef burger with a beef burger reformulated with a portion of cooked lentil puree. The geographic resolution of the analysis was Saskatchewan, Canada. Results showed that partial replacement of a lean beef burger with cooked lentil puree increased the nutrient density by ~20%, decreased the life cycle environmental footprint by ~33%, and reduced the cost by 26%. In particular, the lentil reformulated burger had 60 times higher dietary fiber, three times higher total folate, five times higher manganese, and 1.6 times higher selenium than the all-beef burger. We highlight the importance of using high-spatial resolution inventory of agricultural inputs and characterization factors (impacts per unit agricultural inputs) to obtain more accurate environmental results. The results underscore the potential of food innovation to contribute towards multiple global sustainable development goals.
