It's very excited to share a new article published in AAES with you! Feel free to read and cite if you are working on the same theme for your research! Title: Calcium Carbide and Wood Ash as Environmentally Friendly Soil Stabilizers for Enhanced Subgrade Performance https://lnkd.in/e5GqYgG4 Abstract: This study looks at the potential of waste calcium carbide (WCC) and wood ash (WA) as soil stabilizers to improve the engineering characteristics of subgrade soil. The investigation begins by characterizing the properties of the untreated soil, indicating a liquid limit of 24.6%, linear shrinkage of 7.6%, and a non-plastic nature due to the lack of a plastic limit. In addition, the soil composition comprises a mere 2% of small particles measuring less than 63 μm, while a substantial 74% of the particles fall within the range of 63 μm to 2 mm. The particle density of untreated soil is found to be 2.86, beyond the typical soil limitations. Subsequently, an investigation was conducted to examine the impact of WCC and WA on Atterberg limits, compaction characteristics, and California bearing ratio (CBR) values. The findings indicate that the incorporation of WCC and WA leads to a reduction in the liquid limit by a maximum of 18.70% and linear shrinkage by a maximum of 55.26%. Compaction properties show an increase in optimal water content and a minor decrease in maximum dry density. Importantly, CBR values significantly improved, with the soil treated with 6% WCC and WA demonstrating a CBR value of 26.9%, exceeding the subgrade acceptability requirement in road construction. This study highlights the potential of WCC and WA as cost-effective and sustainable soil stabilizers, particularly in areas where traditional stabilizing materials are limited. More research into optimization and long-term performance can help to realize the full potential of this novel method for soil stabilization.

A great article from EBI on the potential of biochar to decarbonise cement and construction products for the construction industry and positive outcomes on the life cycle analysis. Exciting and interesting times in the coming months.

As UGP continue our research and development with our industrial hemp biochar with the University of Strathclyde in Scotland and Thomas Jefferson University in Philadelphia Pennsylvania its encouraging to see the positive findings in this article from the EBI on the life cycle analysis. Encouraging news as we continue our biochar research to decarbonise the construction industry.

We’re very pleased to share the European Biochar Industry Consortium (EBI)'s position paper on the permanence of biochar storage in concrete. The paper states that biochar can be safely mixed into concrete, creating stable and durable carbon sinks. Here are some of the key scientific findings of the paper: - Biochar produced over 550C contains a significant content of carbon that is considered structurally equivalent to inertinite.  - In concrete, inertinite biochar is an inseparable component of the cement matrix. Only if the concrete were to be subject to extremely high temperatures can the carbon dioxide be re-emitted. Current recycling methods do not reach high temperatures. - At the end of life, most of the concrete material is recovered, either for use as recycled aggregates or downcycled for use as a filler in roads and other uses Here are the key recommendations for different groups: 🔍 𝗖𝗮𝗿𝗯𝗼𝗻 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗢𝗿𝗴𝗮𝗻𝗶𝘇𝗮𝘁𝗶𝗼𝗻𝘀: Consider using biochar in concrete as a way to securely store carbon for thousands of years. 🏗️ 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹 𝗣𝗿𝗼𝗱𝘂𝗰𝗲𝗿𝘀: Connect with biochar suppliers to start creating new concrete products. 💰 𝗖𝗮𝗿𝗯𝗼𝗻 𝗖𝗿𝗲𝗱𝗶𝘁 𝗕𝘂𝘆𝗲𝗿𝘀: See biochar concrete as an important part of your carbon offset plans. 📊 𝗡𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗼𝗿𝘀: Update carbon tracking and environmental standards to include the benefits of using biochar in construction.

The innovative BioCarboBeton project by Fraunhofer researchers introduces a revolutionary method using cyanobacteria to produce biogenic construction materials. Unlike traditional concrete, this biogenic approach not only avoids carbon dioxide emissions but actively sequesters CO2 within the material itself during the mineralization process. Cyanobacteria, capable of photosynthesis, are cultivated in a nutrient solution and mixed with fillers like sand and calcium sources. This mixture is then shaped and solidified, mimicking natural stromatolite formations that have persisted for billions of years. The process harnesses light, moisture, and temperature to drive carbon fixation and mineralization, resulting in robust, biogenic calcium carbonate-based structures suitable for various construction applications. The flexibility of this method allows for diverse products such as insulation materials, bricks, and mortars, demonstrating its potential across the construction industry. Moreover, by sourcing CO2 from industrial waste gases and utilizing renewable fillers, BioCarboBeton supports sustainability and circular economy principles. Scaling up production and optimizing material properties are current priorities, aiming to make eco-friendly biogenic materials commercially viable. Ultimately, this project not only addresses environmental concerns associated with conventional concrete but also pioneers a pathway towards greener, more sustainable building practices. 🌿🏗️ #BiogenicMaterials #SustainableConstruction #CO2Sequestration #BioCarboBeton

On November 8, 2024, despite being affected by the death of my beloved brother who passed on November 7, 2024 (an eve to the day), I was fortunate to present my first paper at the 11th Zero Energy Mass Custom Home (ZEMCH) conference. The chosen section or sub-theme of the conference was SUSTAINABLE NEIGHBORHOOD, and my paper was directly centered on providing Biochar from Rice Straw as an alternative modifier due to it carbon content, silica content, porous structure, high surface area, and environmental advantage which makes it suitable for use in modifying Bitumen. My paper bears the title, "Comparative Study Of The Physical Properties Of Unmodified And Biochar-Modified Bitumen." It was an awesome experience, though I had to present online. Biochar is a solid material produce through a process known as pyrolysis (involving the heating of waste at a temperature ranging from 350 degree centigrade to 900 degree centigrade in the absence of oxygen). Biochars have been used mostly in the field of Agriculture for sustainable plant growth as well as being applicable for treating landfill leachates while minimum attention is being given to Biochar in the field of Transportation Engineering. Hopefully, the abstract of my paper will be shared in due time. #aspiring_civil_transport_engineer #Transportation_Engineering

Mizzou Engineering researchers, led by Dr. Maria Fidalgo, have secured an EPA P3 Phase II grant to develop an innovative solution for removing "forever chemicals" from drinking water. Their team is creating a hybrid filtration system using iron oxide-coated ceramic membranes that separate and actively degrade PFAS compounds. This modular, stand-alone unit operates at low pressure with LED-UV light, making it energy-efficient and cost-effective - particularly beneficial for rural and underserved communities. The project showcases interdisciplinary collaboration between Engineering and the College of Agriculture, Food, and Natural Resources, positioning Mizzou as a leader in PFAS research. With this technology, they're addressing one of today's most pressing environmental challenges while developing scalable solutions for cleaner water. #WaterTreatment #EnvironmentalEngineering #Research #Innovation #Sustainability
