What are the different types of biodiesel waste?

Biodiesel is the main source of alternative energy made of "green" and sustainable raw materials. The advantage of biodiesel is that it reduces the dependence on fossil fuels, causes less pollution and is renewable. One of the disadvantages of biodiesel is the amount of waste produced. Bionaft waste consists mainly of glycerol, also known as glycerin and methanol, with a smaller amount of other impurities. Although glycerol is harmless and potentially useful, biodiesel waste has low purity and is unusable and toxic by the presence of methanol and other substances. Fuel for biodiesel. Another product of this reaction is glycerol. Usually, one part of glycerol is produced for every ten biodiesel parts. In practice, most biodiesels use up to twice as much methanol as it is essentially needed for the reaction to ensure that all oil is converted. Glycerol that is left is therefore contained a large part of methanol and a small amount of soaps resulting from the reaction of the catalyst with vegetable oilm.

methanol can be obtained by distillation and re -used; However, glycerol, which remains, will still contain traces of methanol and other impurities. Glycerol cleaning to make it sales is expensive, and since 2011 so much glycerol has been produced in this way that it is difficult to find the market for it. This means that biodiesel manufacturers can be left with a large amount of low glycerol to be destroyed. Due to the presence of toxic impurities, it cannot be rinsed, distributed on the ground or buried at the landfill site, and the manufacturers may have to pay to take away.

The use of waste on a biodiesel is a challenge, but since 2011 several proposals have been submitted. One idea is to use a strain of common e coli bacteria for converting waste glycerol fermentation into succession and formats - chemicals with a wide range of applications. Another design is a combination of waste fromBioFTs with biomass waste from agriculture to create solid fuel - this has the advantage of reuse of two waste products. The use of waste glycerol combined with other biomass products as raw materials for the production of polyurethane foam has been designed as an inexpensive method of manufacturing this widely used product. Experiments have confirmed that the type of algae called schizochytrium limacinum can convert raw glycerol into docosahexanoic acid (DHA), Omega-3 polyunsaturated fatty acids with well-known health benefits for humans-this is another opportunity to use biological use Biodiesel WASTE.
