Abstract:
First-generation (1G) biofuels, a “green” alternative to fossil-based fuels, face several drawbacks, primarily attributed to the use of edible crops. The utilization of energy crop residues has emerged as a promising solution to address the environmental and socio-economic challenges associated with 1G biofuels. However, it is crucial to ensure that this utilization is carried out in a sustainable and cost-effective manner, taking into account the local context and the unique requirements of different applications. To assess the value chains of residual biomass, a comprehensive evaluation was conducted, considering various economic and environmental factors. The research specifically focused on gathering and analyzing “on-field” data and collection parameters, such as quantities, collection times, fossil fuel consumption, required equipment, workforce, techniques, and barriers. Additionally, the feasibility of these residues as solid biomass fuels was investigated and evaluated through a series of combustion tests conducted using a small-scale biomass boiler with a capacity of 300 kW. The goal is to promote the development of sustainable supply chains for energy crop residues, facilitating their conversion into energy or solid biofuels at a local level. The results indicate that energy crops residues offer significant greenhouse gas (GHG) emissions reduction in industrial applications (district heating, dedicated power plants), however their successful utilization requires the consideration of several factors, including efficient collection methods, composition, availability, and appropriate combustion system, equipped with gas cleaning and ash removal technologies.
