Waste timber pyrolysis in a medium-scale unit: Emission budgets and biochar quality
(Peer reviewed; Journal article, 2020)Pyrolysis of organic waste or woody materials yields a stable carbonaceous product that can be mixed into soil and is often termed “biochar”. During pyrolysis carbon-containing gases are emitted, mainly volatile organic ... -
Wetting-Drying Response of an Unsaturated Pyroclastic Soil Vegetated with Long-Root Grass
(Peer reviewed; Journal article, 2020)This paper investigates the effect of a long-root grass on the hydraulic response of a partially saturated pyroclastic soil. The work is based on both long-term monitoring under atmospheric conditions and short-term ... -
Wetting-induced collapse behaviour of a natural and vegetated coarse pyroclastic soil
(Peer reviewed; Journal article, 2020)Unsaturated pyroclastic soils originated by Vesuvius volcano show a collapsible behaviour upon wetting with a significant reduction in volume and rearrangement of solid skeleton. The paper investigates the role played by ... -
Øysand research site: Geotechnical characterisation of deltaic sandy-silty soils
(Journal article; Peer reviewed, 2019)This paper describes the geology and geotechnical engineering properties of the fluvial and deltaic gravelly-sandy-silty sediments at Øysand, Norway. Geophysical and geotechnical site investigations carried out between ... -
