This article discusses a novel way of purifying biodiesel without using water in the biodiesel purification process.In this work, waterless purification of biodiesel has been investigated using cow dung ash as an adsorbent.

Southeast Asia has considerable resources to produce liquid biofuels sustainably, using biomass feedstocks that would not cause carbon-dioxide emissions or interfere with food supply.

The need for energy security and climate change mitigation have increased blending mandates worldwide; in Southern Africa, demand for biofuels could increase following South Africa’s planned blending mandates. However, land constraints limit local industry expansion, with demand likely to be met in land-abundant countries.

The EU’s 2009 renewable energy directive (RED I) was designed to increase the share of “renewable” fuels in transport. To achieve this the EU imposed a target of 10% renewable energy in transport on EU member states.

As a flexible and competitive source of renewable energy, bioenergy can play a key role in decarbonising energy systems by responding to the needs of a wide range of demand profiles in the electricity, buildings, and transport sectors.

Develops a cost-benefit analysis to compare the impact of three separate policies to spur the additional production of ultralow-carbon fuels in California: a contract-for difference price guarantee, a per-gallon subsidy, and upfront capital grants.

There is overwhelming evidence of the harm caused by the European Union’s current bioenergy policy to people in developing countries, to the climate and to Europe’s own sustainable development. The policy is on a collision course with the Paris climate agreement and the United Nations 2030 Sustainable Development Goals.

According to researchers, eucalyptus-based fuel would initially be more expensive than fossil fuels to make on a mass scale, but would produce significantly less net carbon emissions.
