We continue to see a bevy of unique studies that evaluate the feasibility of waste valorization in various sectors and applications. Produced water seems like an ideal feedstock for this paradigm. Below is a two-part process (oxidation and biological) published by Elsevier where polyurethane waste is converted into biofertilizer components.

Silicone-modified biochar from waste black peanut shells effectively removes copper (II) from water. This low-cost, sustainable adsorbent offers high adsorption capacity and reusability. Its effectiveness is due to increased surface area and porosity, making it a promising solution for industrial wastewater treatment. #Biochar #Pyrolysis #CarbonCapture

Sludge on the road for wastewater treatment? According to the World Bank, around 80 percent of the world's wastewater is discharged into the environment without adequate treatment. Wastewater treatment works (WWTW) are built to address this and treat wastewater before it is released back into the environment. However, over time, conventional wastewater treatment methods have more or less not changed. The treatment process typically involves four stages and integrates physical, chemical, biological, and combined technologies. Currently, novel solutions are being developed and commercialized, mainly targeted at the secondary and tertiary treatment phase, including approaches such as membrane bioreactors (MBRs), advanced oxidation processes (AOPs), and constructed wetlands as a nature-based solution. Furthermore, enhanced resource recovery of energy and nutrients (e.g., nitrogen; phosphorus) from sludge is explored via approaches such as anaerobic digestion (AD) for biogas production, microbial fuel cell (MFC) technology for electricity production, and struvite precipitation for phosphorus recovery. For these solutions, some headwinds are on their way. In the US, the Biden-Harris administration recently announced nearly $6 billion for clean drinking water and wastewater infrastructure, and water treatment and conservation startups raised $787 million in 2023, more than double the $343 million total funding raised in 2019, with companies such as Gradiant ($225 million Series D) and Allonnia ($30 million Series A) leading the stage. Still, enhancements in, among others, industry adoption timelines, government regulations, funding environments, and approval processes are needed for widespread industry implementation. → Dive into advanced wastewater treatment works (WWTW) with our latest Insights piece: https://t.ly/6iTR_ #WWTW #wastewater #climatetech #deeptech #deepsense #techduediligence #expertnetwork

I am pleased to share our recent review article entitled “Lignin: A valuable and promising bio-based absorbent for dye removal applications” published in International Journal of Biological Macromolecules by Elsevier. This manuscript highlights the main achievements in the application of lignin and its derivatives as adsorbing agents for dye removal from aquatic environments, demonstrating the full potential of lignin in dye removal applications.

Biopipe SA water reuse for tomorrow provides opportunities for effluent reuse program. Our team and African Water Works have engaged different government institutions in #Africa in providing EPC sanitation solutions and water reuse programs. Why Biopipe for water reuse? In Biopipe, “no sludge” refers to the system’s ability to break down and fully treat wastewater without producing the thick, semi-solid residue known as sludge that accumulates in most conventional sewage systems. Here’s what “no sludge” means in detail for Biopipe: 1. Complete Organic Decomposition: In Biopipe, bacteria in the biofilm that lines the pipe walls break down organic matter in the wastewater completely. This biological process converts organic waste leaving almost no residual solids. 2. Minimal Biomass Accumulation: Traditional systems produce excess biomass (sludge) from dead bacterial cells and undigested organic material, requiring regular removal and disposal. Biopipe’s biofilm community is highly controlled and self-sustaining, meaning bacteria stay attached to the biofilm without excess die-off. This controlled bacterial growth minimizes biomass accumulation, so the system doesn’t produce significant amounts of sludge. 3. No Settling or Solids Accumulation: The continuous flow design in Biopipe keeps solids moving, preventing them from settling and building up as sludge. As organic particles flow through the system, they are gradually digested by bacteria and other microbes within the biofilm until fully broken down, with no solid residue left behind. 4. Self-Sustaining Microbial Environment: Biopipe’s microbial ecosystem, including bacteria and small organisms, keeps itself balanced by naturally consuming any excess bacteria and organic particles. This “self-cleaning” effect means that the microbial community itself prevents the formation of sludge without external intervention. In essence, “no sludge” in Biopipe means that the system treats wastewater so thoroughly and efficiently that it eliminates the need for sludge removal, making it maintenance-free in terms of sludge management. This is a key advantage over traditional systems that regularly require sludge handling, disposal, and associated maintenance. #Waterfortomorrow #wastewatermanagement #sanitation #sanitationsolution
