“…that degrade lignin in wood waste can enhance the degradation of persistent organic pollutants such as pentachlorophenol (Mileski et al, 1988). Microbial inhibition in biosolids caused by poor aeration, low pH, or high concentrations of metals may be reduced by mixing the biosolids n/g (Paramashivam et al, 2016b), (Wilén et al, 2004) Pine ( (12) 55 (12) (Enders et al, 2012), (Pereira Calvelo et al, 2011), (Hina et al, 2010) n/a n/a n/a n/a (Zhang et al, 2015) 600 9.6 37.1 0.4 n/a n/a 42.6 n/a n/a n/a n/a Lignite New Vale, New Zealand with organic amendments (Song and Schobert, 1996;Pehlivan and Arslan, 2007;Chassapis et al, 2009;Knowles et al, 2011;Simmler et al, 2013;Doskocil et al, 2015).

“…The overall primary pyrolysis stage is completed at relatively low temperatures, around 500 °C (Neves et al, 2011), and yields a C-rich solid: charcoal or biochar, depending on its use. In general, the higher the temperature, the higher will be the pH, C, mineral and ash content, C stability and biochar aromaticity, porosity, and specific surface area, and the lower will be the volatile content and yield (Wu et al, 2012;Zhao et al, 2013;Zhang et al, 2015b).…”

Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its "inspiration" is from the historical Terra Preta de Índios (Amazon Dark Earth), and also because Brazil is the world's largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been carried out and now a vast literature, and excellent reviews, are available. The objective of this paper is therefore to deliver a critical review with some highlights on biochar research, rather than an exhaustive bibliographic review. To this end, some key points considered critical and relevant were selected and the pertinent literature "condensed", with a view to guide future research, rather than analyze trends of the past.

“…Clough et al (2013) reviewed the studies examining NO 3 − sorption on biochar and concluded that sorption of NO 3 − onto a biochar surface was unlikely to occur unless the pyrolysis temperature during biochar manufacture was >600°C, with the degree of NO 3 − sorption also dependent on feedstock type. Other more recent studies, also showing low sorption of NO 3 − by biochar, have generally examined biochar manufactured at pyrolysis temperatures <600°C (Gai et al, 2014; Hale et al, 2013; Zhang et al, 2015). Chintala et al (2013) showed that NO 3 − sorption of a biochar produced at 650°C was only significant in acidic conditions.…”

“…A slow pyrolysis method was used to produce low‐temperature biochars. A muffle furnace was used to manufacture biochars at 350°C in a low‐oxygen environment (Zhang et al, 2015). Sawdust (200 g) was weighed into steel containers covered with aluminum foil.…”

Effect of Pine Waste and Pine Biochar on Nitrogen Mobility in Biosolids

Humanity produces ∼27 kg of dry matter in biosolids per person per year. Land application of biosolids can improve crop production and remediate soils but may result in excessive nitrate N (NO-N) leaching. Carbonaceous materials can reduce the environmental impact of biosolids application. We aimed to ascertain and compare the potentials for Monterey pine ( D. Don)-sawdust-derived biochars and raw sawdust to reduce NO-N leaching from biosolids. We used batch sorption experiments 1:10 ratio of material to solution (100 mg kg of NH or NO) and column leaching experiments with columns containing biosolids (2.7% total N, 130 mg kg NH and 1350 mg kg NO) mixed with soil, biochar, or sawdust. One type of low-temperature (350°C) biochar sorbed 335 mg kg NH, while the other biochars and sawdust sorbed <200 mg kg NH. None of the materials sorbed NO. Biochar added at rates of 20 to 50% reduced NH-N (<1% of total N) leaching from columns by 40 to 80%. Nitrate leaching (<7% of total N) varied little with biochar form or rate but was reduced by sawdust. Incorporating dried sawdust with biosolids showed promise for mitigating NO-N leaching. This effect likely is due to sorption into the pores of the biochar combined with denitrification and immobilization of N rather than chemical sorption onto surfaces.
