Comestoarra.com is an Indonesian small and medium-sized enterprise (SME) focused on creating a decentralized management system to address methane gas emissions and fossil fuel dependency—key contributors to global climate change. In response to these challenges, Comestoarra has developed Community-Based Waste to Energy (TOSS) and Distributed Hybrid Renewable Energy for Community Solutions (DHYRECS). The implementation of these two methodologies is commencing in Indonesia. As an archipelagic country, Indonesia is strategically positioned within the global community to reduce greenhouse gases. In addition, Indonesia's population, the fourth-largest in the world, positions it to become a hub for global industrialization, encompassing production, distribution, and consumption.
A decentralized management system is the chosen strategy for Indonesia's decarbonization and energy transition to achieve the goal of net-zero emissions by 2050. This is due to the challenges inherent in centralized, large-scale projects associated with decarbonization and the energy transition, such as high investment costs, profit-driven models, extended construction timelines, and the risk of project postponement.
TOSS and DHYRECS have been selected because they simultaneously provide waste management solutions and renewable energy applications. The conversion of organic waste and biomass residues into solid renewable fuel can mitigate methane gas emissions into the atmosphere. Furthermore, this solid renewable fuel can be gasified as a substitute for fossil fuels in generators. The energy can be hybridized with existing renewable energy technologies, such as solar PV and batteries, which can contribute to the energy transition. The residue from solid renewable fuel gasification can be used as biochar for carbon capture and storage.
Both TOSS and DHYRECS are in line with the commutative law of algebra, which asserts that 1 × 1,000 equals 1,000 × 1. If stakeholders were to concurrently process 1 ton of organic waste and biomass residues at 1,000 sites throughout Indonesia, the total amount processed would be equivalent to processing 1,000 tons of organic waste and biomass residues centrally at a single landfill. On the other hand, if stakeholders were to implement 10-kilowatt (kW) DHYRECS charging stations in 1,000 locations, and each charging station were to swap 50 electric vehicle batteries and charge 10 electric vehicles a day, it would significantly advance the electric vehicle ecosystem with 100% green energy.
Regarding carbon reduction, according to theoretical calculations, processing 10 tons of organic waste and biomass residue per day could reduce emissions by 1,600 tons of CO2 equivalent per year. The calculation is based on reducing methane gas emissions from landfills, decreasing fossil fuel consumption for waste transportation to landfills, and mitigating individual transportation-related fossil fuel use. If this scenario were implemented in 1,000 locations, it would reduce emissions by more than 1.6 million tons of CO2 equivalent annually.
In conclusion, the objectives of implementing TOSS and DHYRECS encompass not only the energy transition and achieving net-zero emissions but also job creation, local empowerment, human resource development, and support for the Sustainable Development Goals.
Looking at the fact that the waste compositions are dominated by organic and biomass residues, moreover the existing power plants are dominated by the coal fired power plants and diesel engines, comestoarra.com has come up with the idea to process those kinds of waste into solid renewable fuel. To be underlined, the dumped organic and biomass residues material in landfill will produce methane gas (CH4), which 28 times more dangerous compared to the carbondioxide (CO2). In relation with energy transition, solid renewable fuel can be substitution fuel for fossil fuel while the processed organic and biomass residues material can reduce green house gases.

Comestoarra.com has competency in developing and empowering communities to be involved in the community based waste to energy and renewable energy programs. Local community is the key stakeholder of comestoarra.com to create the ecosystem and circular economy to align with the sustainable development goals. In relation to co-firing and de-dieselization program, local community has become the key partner to survey, implement the pilot project, create prototype, data collection, and testing the product of waste to energy in several existing power plants in Indonesia.

Comestoarra.com has developed the AI and IoT technology as the tool to help all stakeholders within the ecosystem of community based waste to energy and renewable energy program to get benefit from the data that has been collected. The most valuable data gained from comestoarra.com’s project portfolios on how to create a high-quality biomass pellet by using waste or different local substances. With AI and IoT technologies, stakeholders can get the abundant data and testing result the material for from co-firing and de-dieselization purposes activities. For the long term activities, the government can monitor all activities from processing to utilizing the organic and biomass residues material for energy, the corporate who has CSR program can get the detail information for their funding decision making process and delivery on the ground, and public will get the information about direct involvement to become agents as well as real time activity and detail information about carbon reduction scores.
