Adequate management of biomass residues generated by agricultural and food industry can reduce their negative impacts on the environment. The alternative use for agricultural waste is production of biogas. Biomass feedstock intended as a substrate for the agricultural biogas plants may include energy crops, bio-waste, products of animal and plant origin and organic residues from food production. This study reviews the potential of selected biomass residues from the agri-food industry in terms of use for agricultural biogas production in Poland. The most common agri-food residues used as substrates for biogas plants in Poland are maize silage, slurry, and distillery waste. It is important that the input for the agricultural biogas installations can be based on local wastes and co-products that require appropriate disposal or storage conditions and might be burdensome for the environment. The study also discusses several limitations that might have an unfavourable impact regarding biogas plants development in Poland. Given the estimated biomass potential, the assumptions defining the scope of use of agricultural biogas and the undeniable benefits provided by biogas production, agricultural biogas plants should be considered as a promising branch of sustainable electricity and thermal energy production in Poland, especially in rural areas.

Nowadays, the reuse of waste products in the construction process is a priority research area. Several industrial and agricultural waste products have been investigated, such as fly ash, sugar cane bagasse ash and rice husk ash. This paper analyzes a very important aspect under intense discussion in the scientific community: the Rice Husk Ash (RHA) grinding process. This paper investigates a low carbon RHA with high pozzolanic reactivity produced under uncontrolled burning conditions. The compressive strength of mortar specimens prepared using both ground and natural RHA were tested for 3-56 days and the capillarity absorption was measured for mortars cured during 28 days. Very promising and interesting results were obtained using natural rice husk ash in the production of blended mortars.

Zero waste agriculture is an agricultural concept oriented around the decomposition cycle of organic materials which integrates agricultural and livestock systems to reprocess waste material. Agricultural waste is used as animal feed while livestock waste/excrement is reprocessed into organic fertilizers. The Regional Partnership Service Program (PKW) aims to assist farmers in developing integrated farming businesses based around zero waste agriculture. PKW was held between May and July 2021 in Tindaki Village, South Parigi District, Parigi Moutong Regency. The implementation of this regional partnership program was carried out through a Participatory Action Programs approach, where partners are directly involved in the adoption and application of the various skills that had been developed. The procedure for activity implementation was carried out through several stages, namely: (a) counseling on zero waste agriculture, (b) training in and application of zero waste agriculture technology in the form of demonstration plots for the application of technological products, (c) coaching and mentoring, and (d) the utilization stage of technology product. The findings from the implementation concluded that the agricultural development training based on zero waste agriculture was a success, and the technology had been adopted by the community, marked by the ability to make and develop compost and liquid organic bio-urine fertilizers. Both types of organic fertilizers had been applied in the demonstration plots to assess their effectiveness in reducing the use of inorganic fertilizers. Rice production is equivalent to 5.6 tons/ha and 6 tons/ha in conventional land. These results show potential benefits for farmers, particularly regarding lower production costs compared to the usage of conventional land. Zero waste agriculture is a method of farming and livestock raising that utilizes their waste products for energy production.

Research works have been made to determine the negative influence of agricultural wasteproducts from peasant fanns to the environment in eastern region of Latvia (Latgale). It isascertained that since Latvia has got independence, great amount of peasant farms have beenestablished which have got from 2 to IO ha of land in property in most cases where peasantskeep cattle, grow crops and vegetables for their needs. As a rule peasant has 1-2 catties, pigs,hens, sometimes sheeps. There are also another farn1s with great amount of land and cattle butnot so many. Technology of waste recycling is used in such farms. State control of waterpollution is also conducted. Ground and underground waters are polluted in peasant farms.The main reasons of pollution are: chemical (mineral fertilizers, pesticides, oil products);bilogical (manure, liquid manure, dead bodies of animals and wastes ); domestic (glass andplastic packages (capacities), polyethylene of greenhouses, used domestic electrical devices).Mass burning of last year's grass in last years is a result of destruction of useful groundmicroorganisms, flora and fauna. Lack of depositories for manure, inappropriate use ofmanure and liquid manure causes too much nitrates in ground and pollution with helmits. Themain reasons of ecosystem's pollution are: individual peasants' low level of ecologicalculture, incomplete legislation. There are a lot of both national and European legislative Actsthat regulate toxicants' influence to the environment but all of them need to be unified.Almost all of the legislative Acts are accesible on the Internet, besides they are requiringpayment, but the Internet is not available for majority of peasants. Activities for reduction ofenvironmental pollution are offered in connection with such situation. Such activities are:perfection of legislation, establishing system of agricultural waste products' gathering, sortingand recycling, establishing depositories for manure and technologies for manure's using,creation of "waste free" technology for cattle's slaughter, meat and dairy production'sprocessing, making the role of State services and public organisations in increasningecological competence of population more important, apportioning extra finances forenvironmental protection in peasant farms.

Natural building materials are diminishing day by day. Hence economical alternatives of natural building materials are necessary for sustainable development. Hollow concrete block was developed to reduce the use of natural building materials. Agricultural waste products like coconut shells from coconut industry have disposal problems causing environmental concerns. Various studies were done in the past, replacing a portion of the natural aggregates with broken coconut shells for manufacturing the hollow concrete blocks. In this study, we have developed a new method of forming the holes of hollow concrete blocks by placing stacks of half portion of coconut shells at the bottom with convex surface upwards to reinforce the holes by arch action. The results show that the coconut shell reinforced hollow concrete blocks have better strength as compared to open-graded hollow concrete blocks available in the market.

Recently, advanced technologies exploit materials from nonrenewable resources such as petroleum, natural gas, metal ores, and minerals. Since the depletion of these resources and environmental issues, it has brought attention to researchers to progress in the development of biodegradable materials from green composites. Most biofibres and biopolymers are obtained from agricultural waste products either from stem, leaf, stalk, or fruit. Nowadays, green composites with well-regulated life span have been widely discussed in numerous fields and applications. Some studies have shown that biofibres and biopolymers have comparable mechanical, thermal, and physical properties with glass fibre and other synthetic polymers. Thus, researchers are progressively narrowing down the development of green composite materials in many high strength applications, such as house deck and automotive components. This review focuses on the background of green composites (natural fibres and biopolymers), the manufacturing processes, potential applications in cross arm structures, and testing evaluations. This article also focuses on the specific current cross arm configurations and the pultrusion process to form squared hollow section beams. Many open issues and ideas for potential applications of green composites are analysed, and further emphases are given on the development of environmentally friendly material structures. Hence, the article is expected to deliver a state-of-art review on manufacturability and perspectives of natural fibre reinforced biopolymer composite cross arms for transmission towers.
