#Biochar is permanent. 💎 Science is about to find its consense. Lets spread the word and lets fix the issue that the most developed, highly durable #BCR gets the pricing it deserves. And that is clearly > 200 €/t CO2 equivalent. https://lnkd.in/dFk9Aq4B

It will be interesting to see if this technology progresses -- to make plants both more resilient to CO2 and more productive. 🌿 🌾 https://lnkd.in/gwTXhKHE #sustainability

Struggling to select the right emission factor? 🤯 Many face challenges when it comes to choosing emission factors for carbon footprint calculations. It's not just about finding any emission factor; it's about ensuring it fits your specific processes. We believe it's a journey. Initially, most begin with generic emission factors. As knowledge grows, collecting primary data becomes essential for accuracy. 🍓 For example, calculating the carbon footprint of strawberries may start with a global average emission factor. But as you learn more, factors like organic production and regenerative farming methods come into play, impacting the final result. Starting with rough estimates is crucial, but moving towards primary data leads to more accurate outcomes. ✨ https://lnkd.in/ddef8m9C

This article from Yale offers a very balanced view of biochar in the context of both CDR and agricultural sustainability, in my view. A clear and concise perspective, with tight messaging for the industry on what is needed to build scale. https://lnkd.in/gZEa4436

BASIC PHOTOSYNTHESIS: Photosynthesis can be defined as the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Plants survive and continue to exist by making their own food which is in the form of glucose. They produce this food by making use of water, sunlight and carbon dioxide in a process called photosynthesis. The specialised cells help the plant to survive by working together to carry out photosynthesis. In most plants, the main site for photosynthesis is the leaf. The leaf is thus, adapted for photosynthesis and all other functions needed to enable a plant to survive. The tiny pores in plant leaf, called stomata, allow plants to take in carbon dioxide. The CO2 moves to the leaf's mesophyll cells which is where photosynthesis takes place and glucose is formed. Usefulness of photosynthesis: Photosynthesis is essential for sustaining life, as it is the foundation of the energy supply for ecosystems and is vital for the oxygen-carbon dioxide balance on Earth. Equation of photosynthesis: 6 CO2 (carbon dioxide) + 6 H2O (water) + light energy → C6H12O6 (glucose) + 6O2 (oxygen) Other basic applications of photosynthesis: 1. Oxygen Production: Photosynthesis provides oxygen essential for the respiration of living organisms and maintains the oxygen-carbon dioxide balance. 2. Food Source: It is the foundation of food chains and supports agriculture, feeding the global population. 3. Energy Storage: Photosynthesis is the origin of fossil fuels and biofuels, supplying energy for industry and transportation. 4. Climate Regulation: By absorbing carbon dioxide, photosynthesis helps mitigate climate change and plays a key role in the global carbon cycle. 5. Medicinal Uses: Photosynthetic plants provide medicinal compounds and contribute to oxygen-based medical therapies. 6. Economic Value: Photosynthesis drives agriculture, forestry, and industries, supporting economies and sustainable material production. 7. Ecological Sustainability: It sustains ecosystems, supports biodiversity, and aids in environmental restoration efforts such as reforestation.

🐔New life cycle analysis from SuperMeat, conducted by independent research consultancy CE Delft found a 47% reduction in carbon emissions versus conventional chicken when renewable energy was used, and even using current energy mixes, there was still a 27% reduction. The startup cites their newly developed continuous method of cultivation (rather than using a batch process which is commonly used) as a major opportunity for emissions reduction, and it compares favourably with other cultivated chicken life cycle analyses by CE Delft which have generally found a more similar emissions pattern between cultivated and conventional chicken. On top of this, similar to other previous studies, cultivated chicken also offered significant reductions in air pollution, soil acidification and feed requirements. Conventional chicken is generally considered the most efficient type of conventional meat, making these findings all the more encouraging. While much research is still needed before innovations such as continuous processes can effectively scale, such developments are hugely promising and underline the potential of this game-changing food. To deliver these on a time scale that would allow cultivated meat to move the needle on pressing problems such as food insecurity and climate change, public funding is keenly needed.

I would be very careful in accepting the conclusions for this comparison given that cultured chicken is not a commercial operation and is at a fraction of a percent of the production level of chicken meat.Therefore the assumptions made about the input costs for cultured chicken are not realistic. These types of comparision are totally unrealistic given the state of maturity of these 2 production processes. This is just a PR exercise.

Technology is finally emerging to tackle the issue of low concentration methane emissions in a way that is generally applicable (ie not limited to just livestock feed). This is really big news because this possibly the most overlooked and underfunded piece of the climate puzzle until now (and thus w. enormous growth potential). Ambient Carbon's MEPS technology formed the basis of a groundbreaking paper just published where they show 58% methane destruction efficiency from low conc. source (see link at bottom). Since publication, this number has risen further in the lab to 88% (!!) Methane is responsible for ~30% of the current rise in global temperature (IEA, 2022) & the vast majority of this stems from low-conc. sources (Abernathy/Stanford, 2023). If commercializing the tech that could really tackle this issue interests you, reach out to me (I know a bit about it), or even better to Professor Matthew Johnson, CEO of Ambient Carbon, to see how you could get involved (or invest). https://lnkd.in/eiH-HVKd

The merging of two critical environmental narratives – the alarming decline in soil fertility 🌱 and the innovative use of waste-to-energy technologies 🏭 to produce soil improvers – presents a sustainable solution with profound implications for our planet's future 🌍. Intensive farming practices, erosion, climate change impacts 🌤️, urbanisation, and overuse of chemical fertilisers are rapidly depleting the Earth's soils. About 33% of global soils are degraded 👎, reducing agricultural productivity and posing a significant threat to food security 🌾. Waste-to-energy technologies can transform what was once waste into a capable resource beneficial to soils. REVALUO W2E plants convert organic waste into energy ♻️, reducing landfill use and greenhouse gas emissions. The by-products of this process, rich in nutrients, can be processed into soil improvers. These obtained improvers are used to restore soil health 🌿, enhancing its structure, fertility, and water-retention capacity. In addition, it offers new revenue streams for waste-to-energy plants 💰 and provides farmers with cost-effective, sustainable alternatives to chemical fertilisers 🚜.

The Only Scalable, Cost-Effective Solution to the Climate Crisis As we confront the urgent need to achieve Net Zero by 2050, it is clear that engineered solutions alone cannot meet the scale required.
