An ICT driven intervention for transforming waste to wealth: methodic development and assessment of IVRI-Waste Management Guide App

The study was conducted in Ludhiana District of Punjab (India) to understand the organic waste management practices followed by dairy farmers of the area. To investigate the practices pertaining to organic waste management, an ex-post facto research design was used and a total of 80 dairy farmers were selected randomly for the study, grouped as small and large dairy farmers. Results revealed that the majority of the farmers were using paddy straw as animal bedding followed by in situ burning. As far as paddy stubbles were concerned, most of the farmers were mulching them followed by in situ burning. All farmers were found to be using wheat straw as livestock feed and mulching wheat stubbles. For household waste, the majority of the farmers were found to be feeding kitchen waste to their livestock, preparing farmyard manure from garden waste and paper waste. For dairy waste management, all the farmers were preparing farmyard manure from dung and discarding livestock urine in drains. A little more than half of the farmers were producing biogas from the dairy waste. The majority of the dairy farmers of the research area were found to have low organic waste utilization scores. Relational analysis was carried out and social participation and knowledge level were found to be highly significant (p < 0.01) with a positive effect on the organic waste utilization score. Therefore, the study was concluded with the impression that the knowledge level of the farmers needs to be enhanced for better and effective utilization of organic waste.

The Ministry of Environment and Forestry in 2020 estimates that waste dumps in Indonesia will be 67.8 million tons. However, organic waste management in Indonesia is still relatively low. The accumulation of organic waste in the landfill, which usually causes unpleasant odors and potentially cause an explosion due to the production of methane gas from natural decomposition processes, can be avoided by prioritizing waste management from the source. An alternative way to handle organic waste is make eco-enzymes because it is efficient, economical, and environmentally friendly. This is the focus of the community service team. The community service method is carried out in three stages, including the preparation stage, the implementation stage, and the final stage. The preparation stage consists of doing a module for sorting organic waste and its utilization (making eco-enzymes). The next phase consists of socialization, education, and training on sorting organic waste and making the right eco-enzymes. The final stage consists of evaluation and making a final report. The expected result after education, socialization, or training has been carried out by the community service team, the community members, especially RT 04 RW 05 Permata Tembalang, know better and understand the sorting and utilization of organic waste.

Practising urban agriculture positively influences household organic waste management habits: A quantitative study from Florianópolis, Brazil.

Everyone, every day, must produce a certain amount of waste, both organic and inorganic. Most of us only care until the "garbage goes out of the house", but less care about how it ends up in the final waste dump. The increase in public consumption is not in line with the optimal waste management capacity either of the government or the community itself. Waste management that is less than optimal will result in environmental pollution and poor public health. Therefore, strategic efforts are needed to empower sustainable waste management to reduce the volume of waste with awareness of applying the 5M concept, namely reducing, sorting, utilizing, recycling, and saving waste; increasing the role of the waste bank; and focusing on the nature of self-reliance.&#x0D; The target of this community service is one of the community organizations in the Bumijo village precisely in RW 08 RT 35 Bumijo Kulon. Namely, Bank Sampah Berseri 35. The problems faced by partners are that the volume of waste continues to increase and the limited provision of land for final disposal and not optimal waste management are not new problems in Indonesia. The production of household waste in the form of organic and inorganic waste is increasing every day; this condition is increasingly worrying if it is not resolved.&#x0D; This service activity aims to strengthen household waste management institutions in the community as well as increase awareness of reducing the volume of waste generated every day and how to manage organic waste through LOSIDA and STACKED BUCKETS activities and making hand waste craft based on creation economic to manage an organic waste, so green environment can be created.&#x0D; The output of this activity is that members of the Berseri Waste Bank and society have an understanding regarding the manufacture of LOSIDA and stacked buckets independently so that organic waste management is more optimal. Every home on RT 35, RW 08, and Bumijo Kulon has LOSIDA and stuck bucket in yard and its used as organic liquid fertilizer

&lt;p&gt;The management of organic waste in urban environments poses significant challenges due to the high volume of waste generated and limited disposal options. Composting is a promising technique for converting organic waste into valuable compost that can be used to improve soil health and reduce the environmental impact of waste disposal. However, there is a need to assess various composting methods to determine their efficacy, feasibility, and environmental benefits in urban settings. This research aims to conduct a comprehensive assessment of composting methods for organic waste management in urban environments. The study will focus on evaluating different composting techniques, including traditional composting, vermicomposting (using worms), and aerobic composting systems. Factors such as process efficiency, compost quality, nutrient content, odor control, and greenhouse gas emissions will be considered in the evaluation. The research will involve field experiments to compare the performance of various composting methods using different types of organic waste commonly generated in urban areas, such as food waste, yard waste, and agricultural residues. Parameters such as temperature, moisture content, pH levels, and microbial activity will be monitored throughout the composting process to assess decomposition rates and nutrient retention. In addition to technical aspects, socio-economic factors and feasibility in urban contexts will be examined, including cost-effectiveness, scalability, community acceptance, and regulatory compliance. The study will also explore the potential for integrating composting into existing waste management systems and strategies for promoting compost use in urban agriculture and landscaping. The findings of this research will contribute to enhancing organic waste management practices in urban environments by identifying the most effective composting methods and providing recommendations for sustainable waste management policies and practices.&lt;/p&gt;

The Ojir application, a mobile-based innovation for organic waste management at Central Malang Waste Bank (BCM), provides an effective solution to streamline the collection and management of organic waste. Addressing environmental concerns such as food scraps, dry leaves, and fruits, the application responds to Ministry of Environment and Forestry (KLHK) data indicating that approximately 61.50% of total waste is organic, necessitating efficient management to reduce waste volume. Established in 2016, BCM faced challenges in manual data management and limited organic waste search capabilities. To address these issues, Ojir was introduced to modernize the organic waste management system. This innovation surpasses traditional waste management by incorporating a process of diversifying organic waste into maggot raw material. Beyond resolving existing waste bank issues, Ojir enhances management efficiency, allowing users to easily track and manage organic waste with increased accuracy. Consequently, the paradigm of organic waste management shifts towards modernity, effectiveness, and efficiency. Aligned with efforts to create a clean and sustainable environment, Ojir represents an innovative step in reinforcing the role of waste banks in handling organic waste in the technological era. The incorporation of the maggot raw material process further exemplifies the forward-thinking approach in sustainable waste management

Before the start of vermicomposting, the large quantity of organic waste generated in the zoo was sold to the public at the rate of Rs. 500 per truck amount Rs. 9500 annually. However, the large profusion of waste was frequently left within the zoo premises imparting an ugly and unhygienic environment for the zoo. To make the park more attractive, self‐sustained (sold high‐quality vermicompost) and keep premises clean, a vermicomposting process was set up on a pilot basis. Vermicomposting of organic waste could have dual beneficial effects by generating an economically viable animal feed protein in the form of worm biomass while alleviating the negative effects of poor organic waste management. The aim of the study was the management of different organic wastes generated in the zoo by using exotic worms and makes the premises financially‐self dependent. The most dung‐producing animals in the zoo are herbivores and droppings of exotic birds are also included, on average below 200 kg or more waste is collected every week in the zoo. Analysis of different physico‐chemical properties of zoo vermicompost showed vermidegraded organic waste is a nutrient rich and eco‐friendly approach. Data were analyzed by using mean ± error.

Organic waste management is becoming increasingly important in responding to current global environmental challenges. In this context, this community service aims to explore the potential for using organic waste as a substrate for hydroponic media in building a greener agricultural future in a sustainable system. The use of organic waste as a substrate for hydroponic media has great potential in supporting plant growth, because it contains available N, P2O5, K2O and C-organic nutrients which are sufficient for plant growth and development. Plants grown in organic waste-based substrates show comparable or even better growth compared to plants grown in conventional substrates. The use of organic waste in hydroponic farming also has a positive impact on the environment. More effective management of organic waste helps reduce environmental pollution and greenhouse gas emissions. This community service program has also succeeded in increasing public awareness and knowledge about organic waste management and hydroponic technology. Thus, the use of organic waste as a substrate for hydroponic media offers great potential in improving organic waste management, increasing agricultural productivity, and reducing negative impacts on the environment. This activity makes a real contribution to building a more sustainable agricultural future and contributes to global efforts in facing increasingly complex environmental challenges.
