This work presents an alternative for adding value to greenhouse crop residues, used for (1) heating and (2) as a CO2 source. Both options are focused on greenhouse agricultural production, but could be applied to other applications. The influence of factors, such as the air/fuel rate and turbulence inside the combustion chamber, is studied. Our results show that for pine pellets, olive pits, tomato-crop residues, and a blend of the latter mixed with almond prunings (75–25%), the thermal losses ranged from 19.5–53.1, 20.5–58.9, 39.9–95%, and 29.4–75.5%, respectively, while the NOX emissions were 30–247, 411–1792, and 361–2333 mg/Nm3, respectively. The above-mentioned blend was identified as the best set-up. The thermal losses were 39.2%, and the CO, NOX, and SO2 concentrations were 11,690, 906, and 1134 mg/Nm3, respectively (the gas concentration values were recalculated for 0% O2). Currently, no other work exists in the literature include a similar analysis performed using a boiler with a comparable thermal output (160.46 kW). The optimal configurations comply with the relevant local legislation. This optimization is important for future emission control strategies relating to using crop residues as a CO2 source. The work also highlights the importance of ensuring a proper boiler set-up for each case considered.

The economic factor is one of the keys to an area that can be advanced and independent. Until now, the community is still dependent on expensive fuel, while using raw materials around the Gading Kasri village is the right idea. One of the pictures to improve the community's economic factor in the Gading Kasri village is how to convert waste into fuel. The benefits obtained are substantial, including helping the community's economy, reducing plastic waste, and turning plastic waste into energy that is useful for cooking, starting motorbikes, and other powers. In this research, the design of the Combustion Optimization Tool for the Distillation of Plastic Waste into Oil Fuel (BBM) was made as an effective solution to produce an energy source in the form of gas oil with a maximum volume when compared to previous designs for similar devices. In this design, a plastic waste burner cross-section is made in the form of a circular crossbar so that the volume of waste and the effectiveness of combustion that is collected can be more in work. Furthermore, this tool will be used by the community in the Gading Kasri Village to be more beneficial for the organization or the general public.
