Biochar application in organics and ultra-violet quenching substances removal from sludge dewatering leachate for algae production

Nejayote and Food Waste Leachate as a Medium for Scenedesmus acutus and Haematococcus pluvialis Production: A Mixture Experimental Design

“…In addition to the decrease in nutrients from the biomass generated by the growth of microalgae, the generated biomass is a by-product that can be marketed to produce biofuels, cosmetics, feed, and fertilizers, among others. Unfortunately, this is limited by its pathogenic properties, so it is necessary to disinfect the leachates [11].…”

Optimising production of a biochar made from conifer brash and investigation of its potential for phosphate and ammonia removal

“…As a lignocellulose biomass, brash can alternatively be converted to a biochar through pyrolysis (high temperature, low oxygen decomposition) (Gao et al, 2022;Mood et al, 2021;Vu and Do, 2021). Biochar derived from lignocellulose material has been effectively used for many purposes previously, including water treatment (e.g., removal of metals, nutrients) (Cheng et al, 2021b;Oginni and Singh, 2021;Rana et al, 2021), leachate treatment (Pap et al, 2021a(Pap et al, , 2021b and in soil amendment to improve soil physical and chemical properties (Fatima et al, 2021;Guo et al, 2021;Rana et al, 2022). Here, we propose that brash from forest-to-bog restoration sites may be converted to biochar, thus creating an added-value product marketable for water treatment, which could offset some of the costs of brash removal in restoration.…”
