British of Ugandan Origin Explore in Green Cement To Save The Environment
By Roperfree
On 7th January 2025, around 5;00 am when I was preparing to go to work, I was privileged to have a conference call with Sarah Kiyingi Kaweesa fellow entrepreneur, an environmentalist, researcher and CEO at Beaty With Environmental Purpose Ltd with sister company BioJigsaw Ltd. Website https://beautywithepl.com Sarah believes in creating wealth through abundance, the natural resources around us, to create something which is impactful to the masses and to make this world a better place to live in. Birds of the same feathers flock together.
Sarah's innovation falls in line with our innovations as we both strive to protect the environment by creating products which are environmentally friendly and cost-effective, such as ISSB innovations, Roperfree Products & environmentally friendly rentals, ie Jkm Vacation Rental Accommodation.
Sarah supports our fighting malaria campaign by buying Roperfree Insect Repellents as she loves to use natural products on her skin while she has driven a lot of referrals to our business in significant numbers.
When I was having a conference call with Sarah, she shared with me that she's working on green cement which is going to be a game changer in the construction industry throughout the world. It took my interest, as in previous years I had introduced to Uganda ISSB (Interlocking Stabilized Soil Block), which is cost-effective and environmentally friendly and could save up to 60 percent of the construction cost, and here we are with Sarah's new exploration.
The Future of Sustainable Construction with Green Cement "Green cement" represents an innovative and sustainable alternative to traditional Portland cement, which is notorious for its high carbon footprint.
Recent advancements in research highlight the potential of algae in mitigating environmental impacts associated with cement production.
How Algae Contributes to Green Cement:
Biogenic Limestone Production: Micro-algae, such as coccolithophores, absorb carbon dioxide (CO2) through photosynthesis and produce calcium carbonate (CaCO3) as a byproduct.
This biogenic limestone serves as a sustainable feedstock for cement, eliminating the need for energy-intensive mining processes
CO2 Sequestration: Algal cultivation systems can capture CO2 emissions from industrial activities, including cement production itself. The algae utilize this captured CO2 for growth, generating biomass that can be transformed into biofuels or used as material in cement production.
Algal Biomass as a Raw Material: Algae can provide bio-based materials suitable for partial replacement of conventional raw materials in cement. This could involve using algal biomass to source silica and other essential minerals
Algal Ash as a Supplementary Cementitious Material (SCM): Following the extraction of valuable components, the remaining algal ash can replace part of Portland cement in the mix, contributing to a reduced carbon footprint.
Advantages of Algae-Based Green Cement: — Carbon Neutral or Negative: Algae's ability to sequester CO2 can lead to cement production that is carbon-neutral or even carbon-negative
Renewable Resource: Algae can be cultivated rapidly and sustainably, making it a viable alternative to traditional cement materials. — Waste Utilization: Algae can thrive in wastewater or other waste streams, further promoting eco-friendly practices.
Addressing Challenges:
While large-scale algae production requires infrastructural investment, our simplified technology is designed to be scalable, economically viable, and low in operational costs. Additionally, technical integration of algae into cement processes is manageable with the support of microbiologists and technical experts.
