TL;DR: In this paper, a comprehensive list of heterogeneous catalysts which have been reported recently is presented, including oxides of magnesium and calcium, hydrotalcite/layered double hydroxide; alumina; and zeolites.

TL;DR: Recycled chicken eggshells after calcination have been used as a nonconventional heterogeneous catalyst for biodiesel synthesis from karanja oil from the pongam tree (Pongamia pinnata).

TL;DR: In this article, the applicability of these catalysts for synthesis of biodiesel along with their reusability aspect is discussed in a review, where the reuse of the solid catalyst is governed by their deactivation, poisoning, and the extent of leaching in the reaction medium.

TL;DR: A thorough understanding of algae and the overall biodiesel production process discussed in this paper is vital so that focused research might lower the costs involved as mentioned in this paper, though it may look simpler to obtain lipids from microalgae, the overall process of choosing an algal strain, cultivation, harvesting, dewatering, and extraction of oil is quite complicated and not economically prudent at this time.

TL;DR: In this paper, the effects of corrosion on the engine parts that come in contact with a newly devel- oped biodiesel fuel and its petrodiesel blend were reviewed. But, the problem related to the use of noncompatible materials as engine parts for biodiesel-run vehicles is dual in nature.
