With the escalating demand for sustainable energy solutions, unconventional sources are gaining attention, including the utilisation of pork fat for biodiesel production. This study investigates the influence of different pig feeding systems, namely swill and concentrate, on the characteristics and performance of biodiesel derived from pork oil. Twelve Large White Yorkshire piglets were divided into two treatments: one following standard feeding practices (T1), and the other exclusively fed with swill (T2). The pigs were slaughtered, and their fat was processed into biodiesel through transesterification. The fuel properties of the biodiesel were analysed, including kinematic viscosity, flash point, fire point, gross calorific value, and low-temperature fuel properties. Additionally, engine performance and exhaust emissions of a biodiesel blend (B20) derived from pork oil were evaluated and compared to commercial diesel fuel using a Kirloskar single-cylinder diesel engine connected to an eddy current dynamometer. Results indicate that both T1 and T2 B20 biodiesel exhibit favourable characteristics comparable to diesel, with promising fuel density, injection duration, mass flow rate, brake-specific fuel consumption, and brake thermal efficiency across various load conditions. Moreover, critical factors such as cetane number and gross calorific value suggest suitable ignition qualities and energy content, highlighting the potential of pork oil-derived biodiesel as a sustainable alternative fuel source.
