Characterization of oil-extracted residue biomass of Botryococcus braunii as a biofuel feedstock and its pyrolytic behavior.
TL;DR: In this article, a green colonial microalga, B. braunii (BOT-22), was characterized as a bio-fuel feedstock in terms of the elemental composition as well as the pyrolytic behavior by thermogravimetric (TG) analysis.
Journal ArticleDOI
Optimisation of biogas production from the macroalgae Laminaria sp. at different periods of harvesting in Ireland
TL;DR: In this article, the best harvesting period of beach cast brown seaweed Laminaria sp. for methane production was selected, while optimising the use of a beating pretreatment and the organic substrate concentration.

Comparison of CO2 and steam gasification reactivity of algal and woody biomass chars
Kawnish Kirtania,Janik Steven Joshua,Mohd Asyraf Kassim,Mohd Asyraf Kassim,Sankar Bhattacharya +4 more
TL;DR: In this article, an algal biomass (Chlorella sp.) char prepared in two different reactors with two gasifying agents (CO2 and steam) and compared that with similar measurements on woody biomass (commercial wood mix) char in a thermo-gravimetric analyser at three different temperatures.

Life Cycle Assessment in environmental impact assessments of industrial projects: towards the improvement
TL;DR: In this article, an integrated Life Cycle Assessment and Environmental Impact Assessment framework is presented to evaluate environmental effects of a product, process or activity throughout its life cycle or lifetime from the extraction of resources to production, consumption, recycling up to the final disposal.

Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.
