This article shows the changes in fiber waste from cotton processing and how it is gradual. The dust emitted in the dry-cleaning shop is only 5-7 mg/m3 of dust, less than the air in the building where the drying machines are located. This is due to the fact that high moisture is absorbed into the dryers, which prevents the separation of fine dust from the mass. The large dispersed dust, even at high humidity, was separated and was unable to disperse in the building. In the drying units, dust that comes with an atmospheric drying agent causes trouble. This dust, even with a rough dispersion, sits in the dryer along with the gas flow to the roof of the building and the ground near the drying shop. The amount of dust released is 500-600 kg/day. In the compartment, the dust emits from the air pneumatic system, which is an indispensable dust in the air drying shop, as well as the dust generated by cleaning machines. This is a powdery fiber, which contains less mineral fractions. The small fractions are composed of mostly dirty particles. Powdered air is also isolated from aspirate systems of gin suppliers, which absorb absorbed air or polluted air from pollutants. Such suction system can be included in the aspiration of the cotton distribution screw. It is established that only one cotton gin industry produces 150-350 tons of fiber per year, industry-wide waste is 5-6 tons, and 70-90% of organic waste is non-toxic. This will serve as a feedstock for the use of animal feed in the agricultural sector. Researches have been carried out to identify the amount of emissions from the ginneries at the Karasu, Mustaqillik and Ginnery factories in the Tashkent region and the Metan cotton gin enterprises in Samarkand region

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

The larvae of the black soldier fly (BSF), Hermetia illucens L., are commonly associated with decaying organic wastes. Over the past 15 years, investigators in China have conducted extensive research exploring the use of BSF larvae to recycle organic materials as a means to protect the environment, while producing products of value, such as protein and bioenergy. Initial efforts were based on a BSF strain from the USA. However, since then, H. illucens strains from specimens collected in Hubei and Guangdong Provinces have been established and used as models to explore the use of this species in sustainable agriculture. China has played an instrumental role in developing an in-door breeding method using a quartz-iodine lamp rather than depend on natural sunlight. This discovery has allowed the establishment of in-door BSF colonies in regions throughout the world where abiotic conditions (i.e. cold temperatures) are preventative. Researchers in China paved the way for using microbes as a means to enhance BSF production including, enhancing BSF egg-laying as well as waste reduction. Furthermore, bacteria from BSF gut or waste can be cultured and used to promote BSF growth, shorten conversion time, and enhanced conversion efficacy. Recent efforts have demonstrated BSF larvae can degrade antibiotics as well as suppress noxious odours in livestock manure. Due to the efforts of research on BSF in China, numerous companies that recycle organic waste at a large scale (>20 tonnes waste digested/day), have been established. Resulting products include insect powder, and live BSFL that can be used as animal feed ingredients for livestock (e.g. eels and frogs), while protecting the environment. Future work will decipher the mechanisms regulating BSF larval conversion of organic waste so that the system can be optimised. However, efforts are still needed at the government level to establish quality assurance standards if this process is truly to become established as an industry in China.

Growing Medium

Leafy vegetables are a daily part of the human diet all over the world. At the same time, a worldwide problem of Se malnutrition is present in human populations, mostly due to low soil Se contents. As plants represent the main source of this element in the human diet, with Se being an essential trace element for humans and animals, plant foods containing Se can be used as an efficient means of increasing the Se in the human diet, as well as in animal feed (biofortification). At the same time, the production of growing media relies on limited peat reserves. The use of earthworms facilitates the production of composted organic masses mostly consisting of organic waste, called vermicompost. The aim of this study was to investigate the influence of three different growing media (commercial peat media, vermicompost, and a 1:1 mixture) on Se biofortification’s efficacy and yield in lamb’s lettuce. The Se biofortification was performed with sodium selenate (Na2SeO4). It was shown that biofortification increased the Se contents such that a mass of only 48.9 g of fresh leaves contained enough Se for the recommended daily intake in human nutrition (55 µg Se/day), which represents a significant potential for solving Se malnutrition. Furthermore, the use of a 1:1 vermicompost–commercial substrate mixture showed a similar performance to the peat growing medium, contributing to the preservation of peat reserves.

Organic Waste Treatment

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Using larvae of the black soldier fly (Hermetia illucens; BSF) to convert low-value residual organic resources into high-value products like protein-rich animal feed ingredients and biofuel while managing organic waste has developed into a global industry. Considering the associated exponential increase in publications dealing with diet conversion efficiency by BSF larvae, it is timely to suggest procedures to arrive at an improved harmonization and reproducibility among studies. This means establishing protocols for describing the basic experiment design, fly colony origin, rearing procedures, reference and experimental feeding substrates, and sampling preparations including microbiota and chemical analyses. Such standardised protocols are instrumental to allow conversion efficiencies to be calculated. Some of these parameters are relatively easy to describe such as giving the origin and rearing conditions, while others are more challenging (e.g. description of microbe community). In this article we discuss and propose such procedures with the aim to arrive at standardisation of how future resource conversion studies with BSF larvae are conducted and how results are communicated.

In conditions of market reforming in all development directions in Smolensk region, there are changes concerning the conditions, rules and principles of branches functioning in social and economic development of the region and its government. The main focus is on the development of only two industries working for export – electricity production and mining industry. The region is located in Non-Black Earth Region and requires investment for the development of its agricultural sector. Therefore, it was decided to eliminate the sphere of agricultural sector, which in pre-perestroika period provided the domestic demand of the country population in pre-perestroika period. Agricultural sector also provided Far East and Polar regions. However, nowadays agricultural production is aimed only at meeting domestic regional demand. Even after the reforms, agricultural sector and its basic part farming continues to be a small island of real business working for domestic demand. It is a backbone component for the economy of Smolensk region, a source of labor market and force application of region rural population. It ensures its food and economic security and has a high potential for rural development. However, at present its position is in a state of crisis, which is associated with low procurement prices for perishable products, the elimination of a processing system and purchase of agricultural raw materials, seed stock, breeding farm, lack of own production of feed additives and animal feed; care of qualified personnel and specialists from the industry and deterioration of the social base (elimination of schools, settlements, hospitals and medical assistants, culture establishments). At the same time, the tasks are set to ensure food security in the context of sanctions, which leads to a noticeable revival of the industry. There are new concepts in industry regulation at the regional level, transformations in management methodology and interaction mechanism for all levels from modernization to processing of end products in accordance with the requirements of the country’s development.

The use of renewable waste for bioenergy production is in discussion because of the concurrence to the food or animal feed. The treatment of organic waste is necessary in order to keep clean the environment. The combination of those proposals, the waste utilization and the production of renewable energy can be combined with several techniques. In Vietnam the energy demand will increase rapidly in the next years, because a lot of people do not have access to electricity. The development of power sources is limited mainly to large central power plants using hydropower and traditional fossil fuels. So in the country there exists a considerable potential for sustainable energy sources like biomass and residues. The biogas potential is large due to the high livestock population. There are more than 30 million animals in farms, mostly pigs, cattle, and water buffalo. There is a high potential for biogas utilization. Biogas production is economic in small and in big plants, so household biogas digesters are one opportunity for production of renewable energy in small villages or cities with a high livestock population. The advantage of anaerobic treatment of organic waste is the work in closed loops. The treatment of organic waste and the utilization of digested sludge from wastewater treatment plants are samples for the circulation of materials after use. The remaining materials can be used in the natural circulation process, because the nutrients such as nitrogen, phosphorous and carbon, and also trace elements remain in the digested matter. In biogas plants a huge variety of substrates can be used. The adaption of biogas technology to the special conditions of the substrates, the increase of the prices for energy, the aim to replace fossil energies with renewable energies will be forced in the next years. Việc sử dụng chất thải có thể tái tạo được để sản xuất năng lượng sinh học là vấn đề còn đang được thảo luận vì sự cạnh tranh với thức ăn hoặc thức ăn cho động vật. Việc xử lý các chất thải hữu cơ là cần thiết để giữ sạch môi trường. Sự kết hợp của các đề xuất đó, tận dụng các chất thải và sản xuất năng lượng tái tạo có thể có thể được kết hợp với một số kỹ thuật.Ở Việt Nam, nhu cầu năng lượng sẽ tăng lên nhanh chóng trong những năm tiếp theo, bởi vì rất nhiều người vẫn chưa có điện sử dụng. Sự phát triển của các nguồn năng lượng chỉ giới hạn chủ yếu là các nhà máy điện lớn trung tâm sử dụng thủy điện và các nhiên liệu hóa thạch truyền thống. Vì vậy, trong nước tồn tại tiềm năng đáng kể cho các nguồn năng lượng bền vững như sinh khối và những nguồn khác. Tiềmnăng khí sinh học lớn do quần thể động vật nuôi rất lớn. Có hơn 30 triệu động vật trong trang trại, chủ yếu là lợn, bò, trâu nước. Tiềm năng sử dụng khí sinh học rất cao. Sản xuất khí sinh học rất có hiệu quả kinh tế trong các nhà máy nhỏ và lớn, do đó, các thiết bị phản ứng tạo khí sinh học ở các hộ gia đình là một cơ hội để sản xuất năng lượng tái tạo trong các thành phố hay làng mạc nhỏ với số lượng lớn các gia súc được chăn nuôi. Ưu điểm của việc xử lý kỵ khí các chất thải hữu cơ là làm việc trong vòngkhép kín. Việc xử lý các chất thải hữu cơ và sử dụng bùn phân hủy từ các nhà máy xử lý nước thải là các ví dụ cho việc tuần hoàn các vật chất sau khi sử dụng. Các vật chất còn lại có thể được sử dụng trong quá trình tuần hoàn tự nhiên, vì các chất dinh dưỡng như phốt pho, nitơ và carbon, và cả các nguyên tố vi lượng vẫn tồn tại trong nguyên liệu đã phân hủy. Trong các nhà máy khí sinh học, rất nhiều loại chất nền có thể được sử dụng. Sự cải tiến công nghệ sản xuất khí sinh học theo các điều kiện đặc biệt của các chất nền, sự gia tăng của giá năng lượng, mục đích thay thế nguồn năng lượng hóa thạch bằng năng lượng tái tạo sẽ là bắt buộc trong những năm tới.
