Composting is the most efficient technique for managing household organic waste; it is the most widely used technique in the world. To improve and accelerate the composting process and produce rich and stable compost, it is necessary to grind and shred organic waste into small pieces to facilitate the degradation of the material by microorganisms. This paper presents the design, sizing, and modeling of a new self-contained, solar-powered, rotating composter with a shredding shaft. This shredding shaft rotates at 350 rpm and must run for 5 minutes before starting the composting process. This innovative machine shreds and composts organic household waste in situ to produce stable, mature compost suitable for agricultural use, providing an effective solution for managing and recovering organic household waste.

The position of composting household waste in terms of waste management at the macro level is very important, because household acts as a source of waste. When organic waste at household can be composted, then the waste transported to landfill will be reduced, so that the transportation costs of transporting waste involved is reduced, beside can extend the life of the landfill. To determine the effectiveness of household-scale composting process using aerobic composter, its potential in reducing household waste generation, as well as the quality of the resulting compost, we conducted this study. The results showed that: the composting process using "composter" aerobics can be run well and fairly effective, as well as describing the process of aerobic decomposition. It is heavily influenced by the composting process of assistance given to environment volunteers. Potential production of compost that can be generated by each family in one year as much as 43 kg, for families who have 1 (one) composter and 86 kg for a family that has 2 (two) composters. While the potential to reduce household waste generation by 21%, to which has 1 composter, and 42% to which has 2 composters. The compost production has good quality because it is free from microbial contaminants (pathogens), meet the requirements of mature compost and generally meet the parameters required by Permentan No 70 of 2011 or SNI compost of 2004.

Abstract Background It is important to use renewable resources to minimize the environmental risks and the composting is one of the most sustainable methods for the management of organic waste. Methods The objective of this work was to evaluate the physicochemical dynamics of microorganisms and to study cultivable microorganisms during the composting process of organic residues in a new model of bioreactor. The formulation of a possible cocktail of microorganisms selected for use as a compound accelerator will be further investigated. In addition, the use of two inoculants (non-commercial inoculum (NCI)) and commercial inoculum (CI)) and a control without inoculant during the composting process will be analyzed to evaluate its efficiency. Composting was performed by mixing organic waste from the garden waste and University Restaurant, obtaining an ideal C/N ratio of 30:1. The composting process was carried out in 1 m3 composters with controlled temperature and aeration. Results The thermophilic phase for all treatments was reached by the second day. Mature compost was obtained after an average of 120 days and composting in all treatments showed an increase in the availability of P and micronutrients. During composting, the population of bacteria and actinobacteria were higher than those of yeasts and filamentous fungi. Conclusions Increased composting efficiency was observed when starter cultures were used, the treatments presented advantages such as greater mineralization of P-available and micronutrients as Mn and Zn, in terms of the quality of the final product in comparison to the control treatment.

     Insects have a vital role in solid waste composting process. Insects are detritus feeders that enhance changing the physical and chemical properties of decomposed materials during composting processes. This behavior makes insects excellent organisms in recycling of organic matter. The present study assesses the success of insects’ population in relation with the degradation of solid waste.  The study was carried out in the glass house facility of the College of Science, Salahaddin University in Erbil City, Kurdistan region of Iraq, using household organic waste. During composting process, three stages of lifecycle of insects were observed and recorded. The total number of insects reached to 1268 individuals, belonging to the orders Coleoptera and Diptera, class Insects. Diptera individuals were the most abundant insects with 95.4% of the total belonged to four families (Muscidae, Calliphoridae, Ulidiidae and Milichiidae). Coleoptera individuals represented 4.6% of the total number, belonging to three families (Promecheilidae, Staphylinidae and Salpingidae). The measured physicochemical characteristics of the compost included: pH, EC, moisture, total organic carbon, total nitrogen, total phosphorous and organic matter. The pH value of the composts ranged from 7.79 to 7.97. Organic carbon content and organic matter content ranged from 20.16 to 26.99 % and 34.67 to 46.23 %, respectively. It can concluded that household waste compost is not just a waste but has the potential to be transformed into a good quality organic fertilizer through composting. Composting can convert solid organic waste into a valuable added material.

Developing means of farming and agriculture is the reason humans live in the world they do today. It is a necessary means of survival, without which there would be famines all over the world. For thousands of years, agricultural was a natural process that did not harm the land it was done on. Environmental impacts caused due to the harmful effects of human activities are a worldwide problem causing global warming and climate change. Too much dependence on the usage of chemical inputs and the burning of farm wastes was identified as the major ones. Since this issues are threat to mankind and to the existing agriculture equipment’s and the shredder machine is one among them. The machines available in the market are powered via fossil fuels which is also contributing to global warming, this directed the researchers to design and develop a Solar-Powered Shredder machine which can be efficiently operated using solar energy without the dependency on fossil fuel. This project aims at providing solar powered automatized vertical shredder machine to our farmers that is compact and can be operated by using solar.

Organic waste has been a threat to society and the environment, both by the amount generated and the inadequate treatment. Seeking solutions to these wastes, composting becomes an efficient process through accelerated biodegradation. The present study aimed to analyze the reuse of organic waste generated in a food establishment in Manaus-AM. The quantitative methodology presented two steps, weighing for three (3) weeks daily, (i) the waste generated in the kitchen and (ii) discarded by consumers, in addition to the total compost generated by the compost, as a basis for treatment of this material, as way of minimizing the amount of these wastes, analyzing the productive activities of this establishment. Given the results obtained it was observed a disposal of almost 30 kg / week, which if estimated, can reach a value of 0.5 tons / year, for each type of disposal evaluated, totaling a value that can reach 1 ton of organic waste disposed of by this small food establishment. Analyzing the composting process, the data show that there is a reduction in the amount of materials generated, due to their transformation into organic fertilizer, obtaining 50% of the total value produced from the waste, thus indicating a solution to the problems arising from the incorrect disposal of waste. organic matter, which is close to 54% of this waste generated in Brazil. In addition, currently about 1.3 billion tons of food is wasted and there are on average about 815 million hungry people in the world, proving to be an alternative of economic, social and ecological viability.

Nearly one fifth of all water used in the world is obtained from groundwater. The protection of water has become a high priority goal. During the last decades pollution of water has become more and more severe. Today groundwater is more and more used in comparison with surface water. Recently we have seen accidents, which can pollute nearly all surface water very quickly. Generally the groundwater is easier to protect, as well as cheaper to purify, and above all it is of better quality than the surface water. During the past two decades, alternatives to the traditional method of treating the water in filters have been developed, that is in situ water treatment i.e. the VYREDOX and NITREDOX methods. The most common problem regarding groundwater is too high content of iron and manganese, which can be reduced with the VYREDOX method. In some areas today there are severe problems with pollution by hydrocarbons and nitrate as well, and with modification of the VYREDOX treatment method it is used for hydrocarbon and nitrate treatment as well. The method to reduce the nitrate and nitrite is known as the NITREDOX method.
