Towards a new paradigm for biodiesel production
Biodiesel,as source of bio-energy,has the potential to decrease most of the actual greenhouse gas emissions in the transportation sector,creating the conditions for a more global sustainable development.Nevertheless,in the past decades has been the subject of many debates.Its massive world production has been hindered by the lack of sustainable raw materials,as well as the effect of cheap petroleum prices.The actual context compels to find ways to assure its economical,technical and environmental feasibility.The aim of this paper is to propose a new paradigm for biodiesel production and use,to be seen as a strategic and decentralised source of bio energy.Our proposal focuses on 3 main pillars,at using biodiesel as energy back up in case of natural catastrophes and eventual geopolitical conflicts that could give certain level of autonomy to many regions of the world; to massively apply the concept of lipid waste management for biodiesel production and to substitute first-generation lipid sources used to produce biodiesel by waste lipids.Specific tasks should be implemented along short,middle and long-term,which cover the implementation of energy policies,a breakthrough approach in the design of bio-oil harvesting systems from microalgae,and alternative uses of biodiesel as a chemical platform to be used in other sectors of transport,such as maritime shipping and aviation.Different possible scenarios are shown to analyse the challenges and opportunities of biodiesel in the short-term.The future of biodiesel production and use is still not clear because of the complex factors that affect this industry.Our proposals could be useful guides for energy policy makers and researchers to use this source of biofuel in a more feasible and sustainable way.
