Abstract Biochar has high potential for long-term atmospheric carbon storage in terrestrial environments, contributing to meeting the UK and global greenhouse gas emission reduction targets. This study investigates emissions techno-economics associated with biochar produced from food waste anaerobic digestate using hydrothermal carbonisation followed by high-temperature post carbonisation. Owing moisture contents, digestates are challenging valorise. However, these low-value feedstocks have steady availability minimal competition other applications. The focuses on supply, production, agricultural field application, transportation activities. Minimising transport through co-locating production facilities digestion displayed mitigation costs of < £100 tCO 2 eq −1 (125 USD ). 88% stable fraction biochar, which is resistant degradation soil, primarily responsible effective removal gases. results net reductions 1.15–1.20 per tonne predominantly due durable (1.7 biochar). Using 50% UK’s projected available 2030 offers a sequester 93 ktCO p.a., requiring 28 at 20 kt p.a. capacity. Sensitivity analysis emphasises influence gate fee charged process digestate, highlighting its importance economic success production. Further studies needed investigate technology enhancements reduce fossil-fuel use provide greater certainty co-benefits application soil. Graphical

Soil nitrogen loss through NH3 volatilization and N2O emissions is a crucial issue in soil ecosystems. In this study, we explored the effects of biochar nitrification inhibitor DMPP (dimethyl-phenyl-piperazinium, inhibitor) vegetable soils under 60 200% WHC (water holding capacity). Five treatments were set: CK (control), urea (N), + (N C), DMPP), C DMPP). Results found that promoted ammonia both moisture conditions, with higher rate accumulation at WHC. maintained high NH4 +-N concentration increased volatilization, but effectively reduced emissions, especially The N treatment further significantly decreased cumulative compared to DMPP. QPCR results showed AOB (ammonia-oxidizing bacteria) copies treatment. Applying alone or by 50.0 45.7%, respectively. ammonia-oxidizing archaea (AOA) responded oppositely DMPP; AOA amounts during culture. At 60% WHC, greenhouse effect potential 39.0 43.2% lower than N, their GWP 13.8 0.08% N. Adding soil's water contents. conclusion, using inhibitors combination more effective reducing active emissions.
