Tech Crunch: Made of Air, a maker of ‘carbon negative’ thermoplastics, locks in $5.8M

"Berlin-based climate tech startup Made of Air has closed a €5 million (~$5.8 million) seed funding round, led by Norwegian sustainability-focused family fund, TD Veen. [...] As the name (kind of) implies, Made of Air (MoA) is producing durable materials for a variety of use cases that make use of (pyrolyzed) wood waste in order to lock up carbon for long periods in the resulting hardened carbon-negative thermoplastic compound. (Which is literally made from biochar and bioplastics)."

Aquije, Camila; et al. (2021): Low tech biochar production could be a highly effective nature-based solution for climate change mitigation in the developing world

Aquije, Camila; Schmidt, Hans-Peter; Draper, Kathleen; Joseph, Stephen; Ladd, Brenton (2021): Low tech biochar production could be a highly effective nature-based solution for climate change mitigation in the developing world. In Plant Soil. DOI: 10.1007/s11104-021-05159-6.

"Aim: To compare the climate change mitigation benefits of nature-based solutions for management of municipal green waste with conventional management. Methods: This study analyzed the carbon footprint of managing one ton of municipal green waste (MGW) in Lima Peru under 4 different scenarios: 1) Final disposal in authorized landfill, 2) Final disposal in informal landfill, 3) composting and 4) biochar production using a low-cost, low tech Kon-Tiki reactor. Results: The results demonstrate the very clear potential for climate change mitigation from biochar production using low tech and therefore accessible technology in a typical developing world context. The carbon footprint of producing biochar was lower than for composting and biochar and compost both had carbon footprints significantly lower than landfilling. Conclusion We argue that the standards used by nascent platforms for trading carbon removal credits generated by biochar should relax the technology requirement to favor engagement and participation of small-scale market participants in low-income countries. Waste management in the developing world presents significant challenges but often starts from a very low base which means there is large potential for reducing emissions, as well as for sequestering carbon."

Podcast: Carbon Removal Newsroom: Biochar, carbon dioxide removal in the US, and geoengineering

"This week on Carbon Removal Newsroom, we’re starting off with an overview of biochar and discussing the main questions and concerns around this technology, including: How does biochar compare to other Carbon Dioxide Removal (CDR) methods? There is a lot of interest in making biochar, but does the market exist to use it? What can governments do to help scale up the use of biochar as a carbon removal technique? Are any governments taking action yet? Next, we transition to the CDR policy agenda in the United States. We look at the California Climate Crisis Act (AB 1395), which would Codify California’s commitment to achieve net-zero greenhouse gas emissions as soon as possible and no later than 2045. If passed, this bill will set California on course to design a more comprehensive policy framework for CDR than exists in any state so far."

Joseph, Stephen; et al. (2021): How biochar works, and when it doesn't: A review of mechanisms controlling soil and plant responses to biochar

Joseph, Stephen; Cowie, Annette L.; van Zwieten, Lukas; Bolan, Nanthi; Budai, Alice; Buss, Wolfram et al. (2021): How biochar works, and when it doesn't: A review of mechanisms controlling soil and plant responses to biochar. In GCB Bioenergy 755 (1), p. 142582. DOI: 10.1111/gcbb.12885.

"We synthesized 20 years of research to explain the interrelated processes that determine soil and plant responses to biochar. The properties of biochar and its effects within agricultural ecosystems largely depend on feedstock and pyrolysis conditions. We describe three stages of reactions of biochar in soil: dissolution (1–3 weeks); reactive surface development (1–6 months); and aging (beyond 6 months)."

Fridahl, Mathias; et al. (2021): Biochar Deployment Drivers and Barriers in Least Developed Countries

Fridahl, Mathias, Simon Haikola, Peter Msumali Rogers, and Anders Hansson (2021): Biochar Deployment Drivers and Barriers in Least Developed Countries. Handbook of Climate Change Management, 1–30. https://doi.org/10.1007/978-3-030-22759-3_324-1.

"‌The chapter concludes that the idea of carbon removal alone is unlikely to motivate widespread biochar deployment in LDCs."

Belmonte, Beatriz A.; et al. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks

Belmonte, Beatriz A.; Aviso, Kathleen B.; Benjamin, Michael Francis D.; Tan, Raymond R. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks. In Clean Techn Environ Policy, pp. 1–13. DOI: 10.1007/s10098-021-02119-7.

"Although recent papers have reported the development of process integration models for optimizing carbon management networks based on either biochar application or enhanced weathering, none have reported models integrating these two NETs in the same system. To address this gap, a fuzzy mixed-integer linear programming model is developed that integrates biochar application and enhanced weathering for large-scale carbon sequestration."
