The gap in environmental impact for HTC of olive mill wastes is mainly due to the water disposal stage required for HTC.
“This gap is mainly due to the water disposal stage required for HTC.”
From Hydrothermal Carbonization of Organic Waste and Biomass: A Review on Process, Reactor, and Plant Modeling (2021) · cites this paper as [127]
The paper says most environmental costs associated with adding HTC to olive-mill-waste treatment relate to liquid-phase discharge (discussion following §3.2.2; page unavailable). But §3.2.2 attributes HTC’s smaller greenhouse-gas savings relative to traditional thermal treatment mainly to lower energy recovery, not water disposal. The claimed explanation therefore does not hold for the environmental-impact gap generally. (LLM, conf=0.83)
Experimental — accuracy not yet measuredThe HTC of olive mill wastes combined with incineration is less environmentally impacting than composting and anaerobic digestion, while no significant improvements are observed compared with incineration and oil extraction.
“Results show that this solution is less environmentally impacting than composting and anaerobic digestion, while no significant improvements are observed compared with incineration and oil extraction.”
From Hydrothermal Carbonization of Organic Waste and Biomass: A Review on Process, Reactor, and Plant Modeling (2021) · cites this paper as [127]
The Abstract says HTC with energy recovery is more environmentally advantageous than composting and anaerobic digestion. But it also says HTC is less advantageous than incineration with energy recovery; section 3.2.2 reports smaller climate-impact savings than traditional thermal approaches, which include incineration with and without pomace-oil extraction. The paper's finding of no significant differences from those approaches is limited to human-toxicity-related impact categories, so the claim overgeneralizes that comparison. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
