“…BioLPG is a renewable and sustainable form of LPG derived from organic waste materials, agricultural residues and other biomass sources with a carbon intensity of around 70-80%, which is lower than that for oil. It is also called renewable propane and biopropane, as it can reduce the carbon footprint and CO 2 emissions up to 80% [10].…”

“…As it can been seen from Figure 1, among all promising production processes, hydroprocessing of vegetable oils (HVO) is the most mature one and, currently, it is the main production route for biopropane, able to produce (via HVO and fats) significant volume of HVO BioLPG with a process performance in the range of 5-8% [11]. Therefore, there is still significant work ahead to implement and test novel technologies able to produce BioLPG at commercial scale and at affordable costs to end users [10].…”

This chapter provides an overview on the outstanding production, distribution and storage technologies that will likely make the liquefied petroleum gas (LPG) and renewable BioLPG expand their utilization as a cleaner alternative to traditional fossil fuels. The growth of the Global LPG Market size will be presented, with a focus on US and the Europe, the Middle East and Africa (EMEA) regions. Moreover, the increment of worldwide policies aimed at reducing greenhouse gas emissions (GHGs) will be investigated. The growth of the LPG market is primarily propelled by the rising demand for a cost-effective and environmentally sustainable substitute of conventional fossil fuels. Concerning the residential sector, the demand for LPG is due to such end-uses as cooking, water heating and other household purposes. Regarding transportation, LPG’s popularity as an alternative automotive fuel (auto-gas) has also contributed significantly to its widespread adoption in this sector. On the other hand, the utilization of BioLPG is also going up since it is chemically indistinct from LPG and so, it can be ‘dropped-in’ to existing LPG boilers and appliances. Finally, the existing barriers and the new developments on this topic will be investigated to understand why LPG and BioLPG could represent a great investment for the future.

“…Compared to fossil-based LPG, bio-propane produced via catalytic hydrothermal decarboxylation of butyric acid derived from biomass can be found at affordable prices. Onwudili and Nouwe Edou found that the selling price of bio-propane excluding CO 2 was USD 2.51/kg; further, the price can be significantly reduced to USD 0.98/kg (less than USD 1.25/kg, the current price of fossil LPG) by incorporating the UK's renewable energy subsidies [64].…”

The world’s rising energy needs, and the depletion of fossil resources demand a shift from fossil-based feedstocks to organic waste to develop a competitive, resource-efficient, and low-carbon sustainable economy in the long run. It is well known that the production of fuels and chemicals via chemical routes is advantageous because it is a well-established technology with low production costs. However, the use of toxic/environmentally harmful and expensive catalysts generates toxic intermediates, making the process unsustainable. Alternatively, utilization of renewable resources for bioprocessing with a multi-product approach that aligns novel integration improves resource utilization and contributes to the “green economy”. The present review discusses organic waste bioprocessing through the anaerobic fermentation (AF) process to produce biohydrogen (H2), biomethane (CH4), volatile fatty acids (VFAs) and medium chain fatty acids (MCFA). Furthermore, the roles of photosynthetic bacteria and microalgae for biofuel production are discussed. In addition, a roadmap to create a fermentative biorefinery approach in the framework of an AF-integrated bioprocessing format is deliberated, along with limitations and future scope. This novel bioprocessing approach significantly contributes to promoting the circular bioeconomy by launching complete carbon turnover practices in accordance with sustainable development goals.

“…Adicionalmente, ambas rutas usan temperaturas elevadas durante la combustión de la biomasa [14], lo que implica un consumo energético elevado, así como costos operativos e impactos ambientales por la emisión de cenizas y material particulado [15]. Debido a ello, se han investigado nuevas rutas de conversión bioquímica como la fermentación de residuos lignocelulósicos para obtener combustible de aviación, el cual tiene un mejor rendimiento y precio de venta que el generado a partir de hidro procesamiento de aceites y grasas [16], o la fermentación de biomasa a ácido butírico para una posterior destilación y conversión del solvente a propano vía descarboxilación catalítica hidrotérmica [17].…”

El gas licuado de petróleo (GLP) es un producto de primera necesidad, principalmente de uso doméstico, que representa el 10.4% de la demanda energética del Ecuador. A falta de mecanismos para la valorización de los residuos lignocelulósicos en el país, se planteó una ruta de conversión de biomasa a butano como sustituto del GLP, mediante un diseño computacional para evaluar su viabilidad técnica, económica y ambiental. Se seleccionó el residuo óptimo para su conversión a GLP en base a la tasa de generación anual y composición físico-química, la configuración de la ruta se diseñó en AspenPlus® con una entrada de 77 t/h de biomasa. En función de los resultados se realizó un análisis económico y de ciclo de vida usando el software openLCA®. La producción de butano alcanzó las siete toneladas por hora y una densidad energética de 26.7 MJ/L. En cuanto al eje económico, el precio de venta mínimo calculado fue de 1.03$/kg, considerando la venta de la lignina como coproducto. De esta manera, el biocombustible fue competitivo con el precio de venta al público de un dólar por kilogramo de GLP. Finalmente, la huella de carbono total del proceso fue de 102 g CO2-eq/MJ, valor superior al estándar europeo de 94 g CO2-eq/MJ. Esta investigación abre la puerta hacia la optimización de los recursos y transformación de la matriz energética del país.
