Reengineering Resilience: Bio-Resilience Bonds For Financing Microbial Infrastructure And Climate Equity, Reece Buckley

COP30

This policy proposal introduces Bio-Resilience Bonds (BRBs), a performance-based financial instrument designed to monetise microbial ecosystem services as measurable climate infrastructure. Microbial ecosystems are crucial for climate resilience, yet they are often overlooked in mainstream adaptation f inance frameworks. Their ability to regulate carbon and nitrogen cycles, reduce methane emissions and enhance soil and water stability (Delgado-Baquerizo et al., 2016) makes them essential assets for climate mitigation and adaptation. With global adaptation needs exceeding £2.7 trillion (UNEP, 2024), this oversight indicates a systemic failure to recognise biology as a form of infrastructure. BRBs transform microbial outputs into localised key performance …

Converting Lignocellulosic Biomass Into Valuable End Products For Decentralized Energy Solutions: A Comprehensive Overview, Ahmed Aboulmagd Dr., Ahmad Mustafa, Shah Faisal, Jaswinder Singh, Boutaina Rezki, Karan Kumar, Vijayanand Moholkar, Ozben Kutlu, Hamdy Thabet, Zeinhom El-Bahy, Oguzhan Der, Cassamo Mussagy, Luigi Di Bitonto, Mushtaq Ahmad, Carlo Pastore

Renewable Mechanical Energy

This review manuscript delves into lignocellulosic biomass (LCB) as a sustainable energy source, addressing the global demand for renewable alternatives amidst increasing oil and gas consumption and solid waste production. LCB, consisting of lignin, cellulose, and hemicellulose, is versatile for biochemical and thermochemical conversions like anaerobic digestion, fermentation, gasification, and pyrolysis. Recent advancements have led to a 25 % increase in bioethanol yields through alkali pre-treatment and optimized fermentation, a 20 % enhancement in microbial delignification efficiency, and a 35 % improvement in enzyme efficiency via nanobiotechnology. These innovations enhance biofuel production sustainability and cost-effectiveness. Decentralized energy systems utilizing locally …

The Optimization Of Ɣ-Al2o3 Production From Aluminium Foil Waste By Precipitation, Nessren Farrag, Yousef Amin

Chemical Engineering

The objective of this work encompasses the application of aluminium foil waste for preparing alumina (Al2O3), by precipitation. The response surface approach is developed for the produced ɣ-Al2O3 phase. Experiments were performed according to a 32 factorial design to evaluate the effects of hydrochloric acid (HCl) concentration, sodium hydroxide (NaOH) that was used as precipitation agent, as well as the calcination temperatures on the purity and yield. The effect of the two independent variables on the response variables was studied by response surface plots and contour plots generated by the Design-Expert software. The desirability function was used to optimize the …

Investigating The Experimental Process For Partial Replacement Of Cement With Sugarcane Bagasse In The Construction Industry, Amany G. Micheal Prof., Rania Moussa, Nadin Dawoud

Centre for Advanced Materials

In the last few decades there has been speedily increasing in the agriculture and industrial wastes. This causes many environmental issues and raises the potential to contaminate the natural resources of living such as water, air and soil. Recently, the amount of organic waste produced daily has been rising, while it is poorly managed. It is either burned or disposed improperly, which effect negatively the environment and public health. On the other hand, during the cement production process many wastes, and pollutants are generated which have major negative impacts on the environment. Cement is considered as a substantial constituent of …

Estimation And Utilization Of Landfill Gas From Egyptian Municipal Wastes, A Case Study, Ali Habib, Ahmed A. Abdel-Rehim

Mechanical Engineering

Purpose

As the first Author had the chance to invest in landfill gas plant (EL Hammam plant) that flare approximately 1000 m3/hr. to generate electricity. Two critical question must be answered in order to proceed with the feasibility study. The three questions are:

1. 1- How many years this landfill gas emission will last?

2. 2- How much energy can be generated from one million ton if landfilled?

3. 3- How much CO2 in tons will be saved during the project life time?

Methods: Experimental method is used to determine BMP (Biochemical methane potential) ton CH4/ton waste. With

results we can know the …
