Abstract. During the twentieth century, U.S. agriculture strived to achieve increased food production in order to satisfy both local and export demands. In many cases, this led to increased farm sizes and an operational separation of crop and livestock production. The trend of increasing centralization and industrialization of agriculture, specifically animal agriculture, has resulted in the concentration of waste products associated with animal production (manures and wash-down water) over relatively small geographic areas that are spatially segregated from crop production areas. Because the distance that manure can be economically hauled for land application has practical limits, the public is concerned that this spatial separation of crop and animal production areas could lead to over-application of manures near animal feeding facilities, and thus potentially increase the transport of nutrients to ground and surface waters. An aggregated analysis (statewide) of crop and animal production in Iowa suggests that about 30% to 40% of current nitrogen and phosphorus requirements for crop production could be supplied from manures and litters generated from livestock production, while about 50% of potassium requirements could be supplied. However, neither livestock nor crop production in Iowa is uniformly distributed across all counties. This unequal distribution suggests that a more disaggregated analysis of crop nutrient requirements and manure nutrient supply is necessary to estimate the risks of excess nutrient loss to the environment. Thus, we evaluated crop nutrient demand and manure and litter production at the county level to determine if excess manure generation is of concern and to locate areas where additional manures could be used. Results showed that several counties are becoming manure rich, but most locations maintain sufficient capacity to use manure nutrients effectively.

Biomass Stove

The stove is one technology that plays an important role in the utilization of energy at the household scale. The biomass stove studied was a blower system gasification stove. In the blower system, oxygen entering the combustion chamber flows continuously according to the needs of combustion. In this biomass gasification stove study, researchers will also use the biomass stove wall or thermal energy into kinetic energy for grinding blowers and charging systems. This study aims to obtain fuel by utilizing biomass or organic waste as biomass stove fuel and get the energy driving the blower and charging system by utilizing a thermoelectric generator system. biomass stoves used in this study use the principle method of Top-Lif Up Draft (T-LUD) Gasifier, a type of gasifier that matches the characteristics of biomass that has high volatile matter, where the stove is designed intended for biomass fuel from agricultural waste products and industry, boiling 1 kg of water is done using wood chips by varying the area of ​​the air flow door, which is 50%, 75%, and 100%. Can be analyzed Comparison of the performance of the biomass cooker stove and the power generated by the thermoelectric generator, at each door width of the air flow results are different, this is due to the mass of fuel consumption and fire temperature. After calculating the highest thermal efficiency results obtained in the area of ​​50% air flow ventilation and obtained power generated 1.83 watts with 100% ventilation flow door area using wood chips.

The bioeconomy includes all sectors and systems that rely on biological resources (animals, plants, micro-organisms and biomass, including organic waste), their functions and principles. The use of new technologies in the national economy is a key moment, which will create opportunities for the production of high - quality products from bioeconomy represented by the different types of activities. In the paper presents some of the basic indicators (socio-economic) applicable in the regional economy of the country, based on the principles and factors specific to each region. The transformation of indicators towards the bioeconomy will give greater opportunities for social and economic prosperity in each region of the country according to its specific characteristics. Biomass is a kind of solar energy conserved in plant and animal organisms. Biomass as a resource includes waste products from animals and human activities. On earth, there is a certain amount of "dead" organic matter that can be used once as a non-renewable resource from organic fuels.

Rearing Conditions

Bioconversion is the process whereby nutrients are recovered from organic waste products, often by flies, to produce value-added products such as protein for animal feed and lipids for biodiesel production. Currently, research and industry focus on a select few fly species for use in bioconversion that are generalists in their feeding behaviour, the black soldier fly, Hermetia illucens L., and the housefly, Musca domestica L. More investigation is needed on species of flies that are more suited to underutilised waste streams, including meat processing waste. Species of flies that breed in carrion, such as blowflies (Calliphoridae) and flesh flies (Sarcophagidae) can be used to reduce meat processing waste and produce a valuable source of protein. In this review, we propose more investigation and use of a wider range of fly species for bioconversion of organic waste. Four blowfly species are recommended for use in the bioconversion of meat processing waste or a mixture of manure waste and meat processing waste. Chrysomya chloropyga (Wiedemann) is a large mammal carcass specialist and has been found to be effective at recovering nutrients from abattoir waste within four days and producing large larvae in the process. Chrysomya putoria (Wiedemann) and Chrysomya megacephala (Wiedemann) naturally breed in carrion and faeces, are associated with pit latrines and respond well under mass rearing conditions, with high egg production. These species would be recommended for a large-scale bioconversion facility that receives mixed waste streams including manure and animal remains. Lucilia sericata is known to produce antimicrobial compounds that assist in wound healing and has been frequently bred and studied and responds well to lab and mass rearing conditions. We recognise the potential obstacles to using alternative species in industrial-scale bioconversion facilities and pose future directions for research to overcome these challenges.
