Rosie Wood - University of Edinburgh, UK
Molecular modelling is a useful tool to study biochars in a systematic and reproducible manner. However, at present, molecular modelling of biochars is a complex task due to the lack of freely available models in literature. In this presentation, Rosie Wood discusses her work on the development of molecular models representative of woody biochars produced a low (400ºC), medium (600ºC) and high (800ºC) highest treatment temperatures. For each biochar-type, a model of the bulk and a model with exposed surfaces has been constructed. All will soon be made freely available via GitHub (https://github.com/Erastova-group/biochar_models) and can be used in a wide range of molecular modelling based studies of biochars.

Silver nanoparticles are very effective in various nanotechnology applications and are used in a wide variety of products, including consumer goods, electronics, and analytical equipment. As the applications of silver nanoparticles increase, the environmental pollution due to silver nanoparticles release is also increasing and affecting especially the aqueous ecosystem. It is
crucial to remove silver nanoparticles from wastewater before it is discharged into other water streams. Biochar produced from the biomass waste could be a suitable adsorbent. This review focuses on collating the latest evidence on silver nanoparticle production, applications, environmental consequences, and cost-effective technological approaches for silver removal from wastewater.

This study has demonstrated that using a eutectic mixture holds several benefits over a pure activating agent. Not only are higher yields obtained, but it also seems possible to optimise the pore formation in specific areas without affecting the overall specific surface area. Addition of specific compounds in a eutectic mixture could lead to tailored pore formation specifically developed for selective adsorption.

Diego Baragano - University of Oviedo, Portugal
Biochar is of great interest for its effectiveness in soil remediation by reducing the mobility of metals. However, its application can mobilize some metalloids, such as arsenic. On the other hand, nanoscale zero-valent iron is another promising material that has proved to be an excellent soil amendment for arsenic immobilization. In this sense, researchers from University of Oviedo and Czech University of Life Sciences Prague have explored the combination or modification of biochar with nZVI for the simultaneous treatment of soils contaminated by metals and metalloids. This seminar presents new advances in this topic with emphasis not only on laboratory experiments, but also on field applications. Impressions from mining and industrial companies will also be presented.

This presentation covers the results of a literature review into the potential of on-farm pyrolysis/biochar in the Scottish upland context. I cover biochar’s likely climate effects, its agricultural applications and the technical challenges of implementing pyrolysis and biochar on a farm. I conclude that if these challenges can be overcome, the most climate-positive application in the Scottish Uplands would appear to be biochar from forestry wastes, pyrolyzed to optimise for high carbon stability and high heat production and applied to cool, acidic soils in order to boost tree or grass growth after having been co-composted with livestock manures.

Elias Sebastian Azzi - KTH Stockholm, Sweden
In Sweden, biochar market development is mainly driven by use in urban applications like tree planting, green roofs, and landscaping soil. New applications for water treatment and concrete are also being developed. We had two research questions: i) what is the environmental performance of biochar products compared to current products? and, ii) how much biochar do we need in a city? We performed life cycle assessments and material flow analysis applied to the case of Uppsala, Sweden. Biochar products tend to perform better when they replace other problematic materials with high impacts, but environmental trade-offs also exists.

Richard Jackson - Standard Gas Ltd., UK
Much work has been done on suitable sequestration pathways for biochar that is derived from 100% plant origins with many accepted methodologies that allow producers to benefit financially through carbon removal credits. Here I look at why the market for this type of biochar has remained small as the feedstock often has to be paid for so the overall process is uneconomic. A way forward lies in developing uses for the biogenic fraction of char from the pyrolysis of household waste where the economics are much more favourable but this requires more work to be done on developing pathways for sequestering that char as it is unsuitable for topical land use.

Anwarul Islam – James Cook University, Australia
Silver nanoparticles are one of the most beneficial forms of heavy metals in nanotechnology applications. Due to its exceptional antimicrobial properties, low electrical and thermal resistance, they are used in a wide variety of products, including consumer goods, healthcare, and electronics. When released into the environment the same antimicrobial properties can present toxic consequences, making it crucial to remove silver nanoparticles from wastewater. Several
removal technologies are available, but adsorption on low-cost materials such as biochar might be the most promising way forward.

This presentation is meant to provide some information on the legal dimension of biochar and to provide an overview of the opportunities and bottlenecks in the biochar value chain. The scope of the presentation is limited to European law and policy and to this moment in time with an outlook on the future. The presentation covers developments in policy that are relevant for the biochar value chain after the publication of the Green Deal and some documents adopted under its umbrella, in particular the Circular Economy Action Plan and the Farm to Fork and Biodiversity Strategies. In addition, some developments in legislation are also considered and explained, namely the new Fertilising Products Regulation and the new Organic legislation. Finally, some bottlenecks are described, i.a. with regards to the waste and the chemicals legislation, and some potential opportunities are highlighted."

Peter Olivier - The Burning Question, USA
The founding story of biochar comprises a lot of enthusiasm about re-establishing a millenia old technology to sequester carbon in soils as illustrated by the discovery of Terra Preta in Brazil. However, a decade after the first wave of a renewed interest in biochar, the industry is still in its infancy. This talk draws a line from the early perceptions and misperceptions of biochar to current obstacles in industrialising the sector.

Filipe Rego - Aston University, UK
Using slow pyrolysis wheat straw char to decontaminate water showed that adsorption performance comparable to commercial activated carbon can be achieved. Lower temperature char was the best performing, removing 95% of an organic dye from solution, which was connected to surface chemical functionalities. Modifications to the process (increasing feedstock moisture content, using CO2 atmosphere, or feedstock KOH-impregnation) allowed in some cases to improve adsorption performance and can potentially lead to better tailored products.
