This study tries to determine sugarcane bagasse ash (SCBA) as a cement replacement material and its effect on the mortar compressive strength, water absorption, setting times, water consistency, soundness, and specific gravity of SCBA (sugarcane bagasse ash) -Portland limestone cement (PLC) blend at cement replacement from 0 - 8 wt.% at interval of 2 wt.%. Calcination of sugarcane bagasse and the obtained ash was conducted at 600°C at 120 mins with a higher Si + Al + Fe content from the analysis of ash obtained via X-ray fluorescence spectrometer and then employed as cement replacement material for this research. The compressive strength was carried out using strength testing machine; consistency and setting times of the blended cement samples were carried out using Vicat apparatus, while the soundness and specific gravity were conducted using Le Chatelier apparatus and density bottle respectively according to ASTM standards. Results showed an increase in the mortar compressive strengths of SCBA-cement blends was experienced as the curing days progressed from 3 to 14 days. PLC blended with SCBA produced an enhanced early strength due to the presence of lime which tends to accelerate the rate of formation of hydration assembly. Whereas at a high cement replacement of 6.0 wt.%, SCBA produced exceptional mortar compressive strength especially at 14 days despite clinker diminution indicating pozzolanic activity due to SCBA content. The optimal cement replacement with SCBA was observed at 4.0 wt.% in comparison with control especially at 7 days and did not adversely affect its strength owing to pozzolanic activity. There was an increase in the water consistency and setting times of SCBA cement pastes as SCBA content was increased from 2.0 – 8.0 wt.% which was attributed to unburnt carbon present in the ash due to its high loss on ignition, LOI. The elongated setting times could also be due to clinker diminution by cement replacement with SCBA and high-water demand. The SCBA-cement blends produced accelerated setting time results compared to PLC owing to lime present in SCBA which enhances early hydration. The volume expansion of the SCBA cement pastes experienced an increase as SCBA was increased due to lower density of SCBA compared to PLC and increased lime content due to increased SCBA content while the specific gravity diminished.

This study examines the impact of ferric iron contamination in mixing water on the bending and shears strength of reinforced concrete beams, addressing a critical yet explored durability concern in modern concrete construction. Although ferric iron is a common contaminant in tropical groundwater, its structural implications remain insufficiently quantified compared to chloride or sulfate ions. The research aims to bridge this gap by experimentally assessing how ferric iron-laden water alters the flexural and shear behavior of reinforced concrete beams. Three beams were cast using a 1:2:4 mix ratio and a constant water–cement ratio of 0.6, two with ferric-iron-contaminated water (5.3–12.3 mg/L Fe³⁺) and one with potable control water, were tested under four-point loading after 28 days of curing. Parameters measured included yield load, deflection, failure load, bending capacity, and failure mode. Results revealed that ferric-iron-contaminated beams exhibited increased deflection, reduced stiffness, and wider cracks relative to the control, indicating stiffness degradation, early corrosion, and loss of bond integrity at the steel–concrete interface. Although one ferric beam attained a slightly higher ultimate load, its larger deformation signified reduced elastic modulus and premature ductility loss. These findings establish that ferric iron contamination significantly compromises both bending and shear performance by altering hydration chemistry and promoting corrosion expansion within the concrete matrix. The implications are far-reaching for construction practices in groundwater-dependent regions, emphasizing the urgent need for water-quality assessment and regulation in concrete production. This study contributes empirical evidence for refining mixing-water standards and calls for sustainable engineering policies to mitigate corrosion-induced failures in reinforced concrete structures.

There is the ever-increasing plastics waste leading to serious environmental and economic challenges, which need to be addressed through sustainable recycling solutions. The quality of the recycled plastics is limited due to the degradation of the polymer and contamination in traditional mechanical recycling approaches. New chemical recycling technology is an alternative which allows the depolymerization of plastic down to the practical monomer, recovering it in high purity and offering closed loop recycling. The focus of this review is on the integration of pyrolysis methods in the area of chemical recycling which mainly provides means of enhancing the management of plastic waste. Furthermore, the environmental and economic impacts of chemical recycling are evaluated based on a Life Cycle Assessment (LCA) study and compared to the mechanical recycling as well as landfill disposal. However, its promise is yet to be widely adopted due to many challenges including high energy consumption, process scalability, economic feasibility, etc. Future research should aim towards finding ways to optimise catalyst efficiency, reduce operational costs and also integration of chemical recycling within the framework of the circular economy. Chemical recycling technologies should play a strategic role in reducing the global plastic waste crisis and their large-scale implementation will be crucial and need to be facilitated by strategic policy interventions and industrial collaborations.

The accumulating piles of plastics have emerged to be among the greatest environmental issues across the world because of their inability to degrade, the low recycling rates, and non-biodegradability. Gasification has potential as a sustainable and technologically encouraging pathway towards converting plastic waste into useful energy carriers, and, in particular, synthesis gas, a mixture of hydrogen and carbon monoxide. As opposed to incineration, gasification is controlled with the oxygen conditions, which transforms the plastics into clean syngas with less emission and more energy efficiency. By facilitating the recovery of energy, reuse of resources, and the possibility of downstream generation of fuels and chemicals, this process promotes waste reduction as well as the objectives of the circular economy. The current paper is a review of the gasification of plastic waste, focusing on the mechanism of the process, reactor configuration, operating parameters, the composition of the syngas, and its environmental performance. It also addresses the concept of techno-economic viability and the results of life-cycle assessment and integration in the context of the circular economy. Even though there are still some challenges, such as tar formation, feedstock heterogeneity, and scalability, the improvement of catalytic reforming, co-gasification, and integration of renewable energy is improving the possibility of large-scale implementations. Gasification, therefore, is an important way forward in ensuring sustainable waste management and a low-carbon system of energy, which helps to not only protect the environment but also enhance economic strength.

Plastic waste has become an issue of serious concern because it is persistent, not biodegradable, and greatly inefficient to recycle. The traditional mechanical type of recycling is restrained by the degradation and contamination of plastics, whereas the thermochemical process typically requires large energy inputs and yields complicated by-products. Hydrolysis also presents a scientifically viable alternative, which will allow chemical depolymerization of condensation-type plastics (polyethylene terephthalate (PET), polyamides (PA), polyurethanes (PU)). The reaction works through cleavage of the ester, amide, or urethane bonds in the presence of water, acids, or bases as reactants to generate high-purity monomers that can be repolymerized or used in industry. In this paper, the performance of hydrolysis-based plastic waste recycling has been reviewed, including the mechanisms, catalyst development, process parameters, and relative environmental performance. According to life-cycle and techno-economic analysis, hydrolysis will prove to be capable of generating significant carbon reductions and energy savings compared to pyrolysis and incineration with the optimization of reaction conditions and solvent recovery systems. Although scaling, reactivity, and purification of monomers are still problematic, heterogeneous catalysis, solvent engineering, and integration of renewable heat development all increase the promise of using heterogeneous catalysis as an effective tool in ensuring sustainable polymer recycling and material recycling.

Management’s decisions are dictated by the anticipated results from an investment. In the case of oil and gas, the Petroleum Engineer compares the estimated costs in terms of dollars for some investment opportunity as against the cash flow resulting from production of barrels of oil or cubic feet of gas. This analysis may be used in formulating policies for exploring and developing oil and gas properties. The present work therefore aimed at comparing two of the various methods of estimating reserve. These methods are: Volumetric and Decline Curve Analysis. The volumetric method of estimation was based on a detailed geological analysis. The Area Vs. Depth graph was plotted using planimetry readings, and this was used to estimate the reservoir bulk volume. Arithmetic averages of petrophysical data from five wells were used. The Net-To-Gross ratio of the average sand thickness was estimated from log responses; and thus, the reserve was estimated with this method. The decline curve analysis was based on observed production history. The reservoir used in this work shows an exponential decline trend with a constant. Thus, the-reserve was estimated with this method.
