Summary of "Experimental and model enhancement of food waste hydrothermal liquefaction with combined effects of biochemical composition and reaction conditions."

Excessive food waste presents an opportunity to simultaneously alleviate waste and produce renewable resources. The present work uses hydrothermal liquefaction (HTL) with elevated temperatures (280-380 °C) and times (10-60 min) to convert categorized food residues collected from a university campus dining hall into biocrude oil. Analysis of distinct feedstocks presented different biochemical compositions (protein, carbohydrate, and lipid) and yielded between 2 and 79% biocrude oil for the respective optimized HTL temperatures and times. Reaction pathways and elemental distributions (C,H,N) elucidated HTL product qualities based on feedstocks and optimized reaction conditions. Both descriptive HTL process energy recoveries and consumption ratios are included. An improved predictive model was able to accurately determine biocrude oil yield (R 98.3%) of different food wastes under different reaction conditions, as well as predict previously published data (R 94.3%). Combined experimental and analytical results were used to assess the sustainability and robustness of the HTL process.

Medical and Biotech [MESH] Definitions

A process of waste disposal involving the conversion of green waste (i.e. leaves, organic matter, food waste, manure) into soil-enhancing matter.

Waste products which, upon release into the atmosphere, water or soil, cause health risks to humans or animals through skin contact, inhalation or ingestion. Hazardous waste sites which contain hazardous waste substances go here.

The withholding of food in a structured experimental situation.

Statistical formulations or analyses which, when applied to data and found to fit the data, are then used to verify the assumptions and parameters used in the analysis. Examples of statistical models are the linear model, binomial model, polynomial model, two-parameter model, etc.

Sites that receive and store WASTE PRODUCTS. Some facilities also sort, process, and recycle specific waste products.
