Esters from frying oil, sewage scum, and domestic fat trap residue for potential use as biodiesel

Technological application potential of polyethylene and polystyrene biodegradation by macro-organisms such as mealworms and wax moth larvae

“…GWP considers the cradle-to-gate emissions related to natural gas and electricity supply and consumption in Europe. We estimate the GWP for potentially converting the lipids from the mealworms to biodiesel using insights and data from Dufour and Iribarren (2012), Mu et al (2016), Mehta end Anand (2009), Silva et al (2019) and Hums et al (2018), which describe operations for fractionating and converting lipids in sewage sludge and scum from wastewater treatment facilities, and final biodiesel properties. We assume the biodiesel offsets low S diesel with GWP 93 g CO2-eq.…”

Bioenergy from biofuel residues and waste

“…They looked at these potential forfeits for a range of different crop residues production processes including thermochemical conversion, biochemical conversion, and chemical treatment. Silva et al (2019) used waste oil, wastewater scum, and domestic fat trap residues to produce biodiesel. They determined the contest of esters of biodiesel by triacylglycerol and microscale open column chromatography.…”

“…Neves da Silva et al (2019) assessed the impact of the organic loading rate from dairy wastewater on biohydrogen production. This study focused on anaerobic fluidized-bed reactors that were inoculated with natural fermentation processes within the dairy wastewater during daily operations.…”

Spectrometric Determination of Content of Methyl Palmitate in Methyl Esters of Waste Cooking Oils

“…The research conducted by Xu (Xu, 2016) compared and showed the total cost of biodiesel production in China from waste fats (USD 979 per tonne) and palm oil (USD 1145 per tonne), which proves the economic benefits of using waste fats as a raw material for the production of liquid biofuels. The European quality standard EN 14214 provides for thresholds of 25 biofuel quality parameters that comply with the requirements of motor-vehicles users (Silva, 2019). According to this standard biodiesel should not contain free fatty acids and its acid number should not exceed 0.5 mg KOH/g.…”
