Production of engineered algal biochar through microwave pyrolysis for nutrient recovery from aqueous solution
In this study, nitrate and phosphate were recovered from secondary treated domestic wastewater using microalgal biochar (Spirulina sp.). The biochar was obtained by microwave pyrolysis of algae at 400 W power for 10 min. The biochar was modified using Mg(OH)2 under different conditions. Three pre-and post-treated biochars with varied Mg(OH)2 percentages (2%, 4%, and 6% by weight) were produced. All the modifications in biochar improved its specific surface area. Highest specific surface area of the modified biochar reached 33 m2/g compared to 12 m2/g of the unmodified biochar. SEM analysis showed improvement in the poro...

A short review of recent discoveries in montmorillonite ‐based photocatalysts for organic dye water pollutant degradation
AbstractOrganic dye pollutants are the most common type of pollutant found in water and wastewater as a result of various industrial activities. In particular, one of the largest contributors is the textile industry, which uses a lot of organic dyes to produce its goods. Organic dyes that remain in the effluents are typically permanent and difficult to detoxify using traditional wastewater treatment strategies. Photocatalysis using semiconductors have emerged as an attractive wastewater treatment method for resolving the major drawbacks of traditional methods. Montmorillonite has been presented as a conceivable dye adsorbe...

Physico ‐chemical characterization of Residual Household Waste for energy recovery in insular territories: Case study of Reunion Island
This article reports on the composition of Residual Household Waste from Reunion Island and its physico-chemical parameters. Twelve representative samples of Residual Household Waste were subjected to thermal and elemental analysis. The results showed that their composition had a significant influence on the physico-chemical properties, including calorific value. Residual Household Waste from the selective sorting (rich in wood, plastic, and sanitary textiles) as well as dry mixed RHW are the most interesting for energy recovery. Due to their high volatile matter and high carbon content, and their low moisture content, the...

A review on environmental effect of various designs and types of drying methods
AbstractFruits and vegetables are nutritious and good in minerals, vitamins, and fib. Most fresh fruits and vegetables contain a minimum of 70% of moisture content which causes the formation of bacteria, fungi, and viruses to affect and cause the items to rot. But dried fruits contain only less than 20% of moisture content. So drying the fruits and vegetables helps to preserve the items for longer use without causing them to rot. Dried fruits have a great source of antioxidants and help in health benefits like improving blood flow, and reducing the effects of many diseases. Compared to fresh fruits, dried fruits are good i...

Biohythane production from pineapple peel using Methanosarcina mazei enhanced with palm oil mill effluent (POME) sludge in single ‐stage anaerobic digestion
This study focuses on the effects of the lignocellulosic pre-treatment method, the addition of POME sludge intoM. mazei culture medium as inoculum, and various operational conditions (food to microorganisms (F/M) ratios, temperature, pH) on gas production performances. The experimental results indicate that these parameters influenced the efficiency of biohythane production by producing the peak maximum biohythane production rate values (HPRmax) and (MPRmax), H2:CH4 = 1.93:0.67 L/L-d, and biohythane yield (HY) and (MY), H2:CH4 = 1.18:0.55 mL/L-substrate. This study demonstrates that biohythane gas (H2 + CH4 + CO2) ...

AbstractFor a thorough investigation of the combustion, performance, and emission characteristics of coconut oil distillate biodiesel under various engine loads and a constant engine speed of 1500 rpm, a Kirloskar 4-stroke, single-cylinder, the air-cooled diesel engine is used. A total of three fuel samples, such as 100% biodiesel, B20, and B30 biofuel are used respectively. There is a 5% increase in brake thermal efficiency (BTE) for biodiesel and its blends as compared to diesel. The HC, CO, and Smoke are reduced except NOx. Reduction of harmful gases is possible in biodiesel usage and its blends. It is concluded that ...

Performance, combustion, and emission of a diesel engine fueled with an eco ‐friendly mixture of two biodiesel blends
AbstractFast depletion and higher emissions of fossil fuels are posing problems to scientists across the globe. To overcome this, thorough research is needed to find out alternate renewable sources. Biodiesel is such a renewable, biodegradable, and innocuous fuel to meet this global need. Oil extracted from vegetable oil seeds is processed into biodiesel by the transesterification process. The experimental work is carried out to study the performance and emission characteristics of a single-cylinder, air-cooled diesel engine by using a mixture of two diverse biodiesels namely Pongamia and Mahua. The results indicate that a...

Optimization of carbon dioxide absorption in a continuous bubble column reactor using response surface methodology
AbstractCarbon dioxide absorption using amine based solvents is a well-known approach for carbon dioxide removal. Especially with the increasing concerns about greenhouse gas emissions, there is a need for an optimization approach capable of multifactor calibration and prediction of interactions. Since conventional methods based on empirical relations are not efficiently applicable, this study investigates use of Response Surface Methodology as a strong optimization tool. A bubble column reactor was used and the effect of solvent concentration (10.0, 20.0 and 30.0 vol%), flow rate (4.0, 5.0 and 6.0 L min−1), diffuser p...

Assessment of tropical suburban surface soils contamination from Jengka, Malaysia
This study assessed the concentrations of Cr, Zn, Pb, and Cd in Jengka (Malaysia) suburban soil and estimated the human health risk. Health risk assessment (HRA) was utilized to assess non-cancer and cancer risks. The concentrations of heavy metals increased in the following order: Cd < Zn < Cr < Pb. The heavy metals were found to be divided into two components using principal component analysis (PCA), with PC1 comprising Pb and Cd and PC2 containing Zn and Cr. PC1 originates from anthropogenic sources, while PC2 is often from mixed anthropogenic and natural sources. Despite having the low est mean conce...

Forecasting the impact of meteorological parameters on air pollutants in Andhra Pradesh using machine learning techniques
AbstractIn the 21st century, air pollution has emerged as a significant problem all over the globe due to a variety of activities carried out by humans, such as the acceleration of industrialization and urbanization. SO2, NO2, and NH3 are the key components contributing to air pollution. Moreover, these air pollutants have a significant connection to several climatic characteristics, such as the speed of the wind, the relative humidity, the temperature, the amount of precipitation, and the surface pressure. As a result, machine learning (ML) is regarded as a more effective strategy for predicting air quality than more conv...
