The coffee industry is a major contributor to carbon emissions due to the energy-intensive process of coffee roasting. This project report explores the feasibility and potential benefits of introducing a solar-powered coffee roaster as a sustainable solution to reduce carbon emissions in coffee processing. The report begins by examining the current en-
vironmental impact of traditional coffee roasting methods and the significance of carbon emissions in the context of climate change. It then presents an in-depth analysis of solar energy as a clean and renewable source, highlighting its suitability for coffee roasting. Next, the design and development of the solar-powered coffee roaster are discussed, including the integration of solar concentrator, energy storage systems, and efficient heating mechanisms. The technical specifications and performance characteristics of the solar roaster are presented, demonstrating its ability to achieve desired roasting profiles while minimizing carbon emissions. An evaluation of the economic and environmental benefits is conducted, comparing the solar-powered roaster with conventional roasting methods. The analysis includes cost savings from reduced energy consumption and carbon credits obtained from the mitigation of greenhouse gas emissions. The potential for scalability and wider adoption of solar roasters within the coffee industry is also explored. Furthermore, the report addresses potential challenges and limitations associated with solar-powered coffee roasting, such as intermittent sunlight availability and initial setup costs. Lastly, the project report concludes with a comprehensive summary of the findings, emphasizing the significant reduction in carbon emissions achieved by adopting solar-powered coffee roasters. It highlights the importance of sustainable practices in the coffee industry and the role of renewable energy technologies in mitigating climate change. Overall, this project report demonstrates that introducing solar-powered coffee roasters has the potential to significantly reduce carbon emissions in coffee processing while promoting sustainability in the industry. The findings provide valuable insights for coffee producers, environmentalists, and policymakers seeking to minimize the environmental impact of coffee production.
