Biochar: Production, Characterization and Applications

Most soil-related applications of biochar have involved agriculture or horticulture. Our current research focusses on remediation of contaminated soils using biochar or biochar compost. We will present the results of outdoor pot and plot trials on three contrasting site types: 1) colliery waste; 2) cleared invasive rhododendron; and 3) metal-mine tailings. All experiments utilized sustainable, lignocellulosic biochar (EarthChar®; UK Biochar Quality Mandate: High Grade), produced using a modified BigChar-1000 fast-pyrolysis/gasification unit equipped with a thermal oxidiser.

Faculty of Engineering and Information Sciences - Papers: Part A

This study investigated effects of mature compost on gaseous emissions during composting using pig manure amended with corn stalks. Apart from a control treatment, three treatments were conducted with the addition of 5% (wet weight of raw materials) of mature compost: (a) mixing raw materials with mature compost at the beginning of composting; (b) covering raw materials with mature compost throughout the experimental period; and (c) covering raw materials with mature compost at the start of composting, but incorporating it into composting pile on day 6 of composting. Mature compost used for the last treatment was inoculated with 2% (wet …
