Microalgae with low lipid content or deoiled microalgae biomass can be used as binding agent. Furthermore, it also enhance the calorific value of briquettes.
Dear Dr D. Ramesh,
This should be possible, provided the microalgae has sufficient lignin content. However, the efficiency of its binding capacity will also depend on the feedstock raw material it is used to bind. Hope this helps.

"Micro-algae is now viewed as a source of bio-diesel and chemical building blocks, which can be used in coatings and plastics. Biomass extracted from algae provides a sustainable alternative to products and fuels from the petrochemical industry."
I don't know why you think low lipid microlagae will enhance the calorific value of briquettes - I suppose if you had a low enough energy material in the briquette it would.
Most microalgae have about 25% nucleic acid and similar nitrogenous material, and about 65% of protein and lipid, the ratio of these two varying considerably depending on the local nitrogen content. Miroalgae, in the presence of lots of nitrogen, make protein and nucleic acid and reproduce like crazy; if they are starved of nitrogen their photosynthesis has to go somewhere and they make lipids, so the ratio depends on where they came from. As an aside, biodiesel is a poor use of the lipid fraction. In my view, hydrothermal liquefaction under the best conditions is far superior because it also isolates hydrocarbons from things like lipoprotein - you can increase the yield of hydrocarbon very significantly over extraction and making biodiesel. And better still, you can make some other valuable chemicals and solvents. I know because I have done it, at least on the lab scale.
Briquette and burning is a major concern.
Use the grade -3 biomass as direct source of biodiesel in Auto thermal liquefaction.
Mixing grade -3 with grade -1 biomass for briquettes is slightly confuding for me.
