🚨NEW STUDY🚨

🌲"#Sequestering C in forest ecosystems is important for mitigating #ClimateChange."

✍️"Policy concern: whether forests should be left unharvested to reduce CO2 #emissions & store C, or harvested to take advantage of potential #CarbonStorage & #removal."

So, new study addressed this issue "by examining C rotation ages that consider commercial timber and C values. A discrete-time optimal rotation age model is developed that uses data on C #fluxes stored in living & dead biomass as opposed to C as a function of timber growth."

"Carbon is allocated to several ecosystem and post-harvest product pools that decay over time at different rates. In addition, the timing of #CarbonFluxes is taken into account by weighting future carbon fluxes as less important than current ones."

🚨 PAPER 🚨

A viable & novel formula for a #CarbonNegative, environmentally friendly #concrete that is nearly as strong as regular concrete has been developed recently at Washington State University.

#Concrete
#Biochar
#CarbonSequestration

*Summary* in a🧵 below:

🧫 Researchers exemplify "a synergistic C-capture strategy, i.e., using #concrete washout water & #biochar together to achieve carbon-negative concrete."

"This strategy enabled the biochar to #capture 22.85 wt% air-borne CO2, which precipitated CaCO3 onto the biochar."

🔬"This carbon-negative cement paste consisted of 30 wt% CO2-weathered #biochar and 70 wt% portland limestone #cement, which achieved the 7-day and 28-day compressive strengths of 22.1 MPa and 27.6 MPa, respectively," microscopic investigation revealed.
