Pectin extraction from various fruits and its application in food products have been debatable issues for ages. We conducted our research on the biomass wastes of the food industry, primarily banana (Musa Acuminata) peels, in order to develop a modified procedure for the effective extraction of this...

Dewatered sludge is the main by-product from wastewater treatment and it contains various types of hazardous substances which can cause environmental pollution. The alternative utilization of sludge waste is for covering the landfill or as liner for the landfill. Landfill cover is a critical...

This research focuses on hydrothermal gasification (HTG) and hydrothermal liquefaction (HTL) studies to produce bio-hydrogen from domestic mixed waste. HTG and HTL studies were studied at temperatures of 300–450°C and 300–400°C, correspondingly, with a catalyst level of 6 wt %. The sol-gel technique...

Industrial wastes represent a huge issue for the environment and precious materials for microbial growth. Utilizing these wastes in different fermentation process decrease the costs of production, materials, energy, and represent an eco-friendly way of waste recycling. Aspergillus niger (ASU49) is...

This work focuses on the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging concern pollutant paracetamol (PCM). The magnetic core of the catalyst is composed of CoFe2O4 developed by a sol-gel method. The core is...

This essay deals with the prospects of supplying humanity with energy in the twenty-first century. The gradual replacement of fossil fuels by green electricity, hydrogen and biofuels is examined in the context of deteriorating climate change and the ongoing depletion of fossil fuels. The production...

Throughout the various stages of the life cycle of a building, a significant amount of CO2 is released into the atmosphere: in the production of goods and materials, the construction of the building itself, the preparation of the site, the exploitation, the repairs, the subsequent rehabilitations...

The dairy industry is one of the industries that continues to grow in Indonesia in line with the large demand for dairy foods. Liquid waste originating from the dairy industry has a special character, namely susceptibility to bacteria. This waste is very easy to decompose and if it is not...

250 million people worldwide suffer from visual impairment. 64% of them wear glasses. More than 80 percent of all eyeglasses worn today have plastic lenses. Plastic lenses made of polycarbonate discs are created through the process of machining which requires the use of a coolant. The ensuing...

Anthracene and phenanthrene belong to a group of persistent environmental contaminants called PAHs. Evaluation of the structure of two selected PAHs i.e. anthracene and phenanthrene on their resistance to destruction by UV-activated PDS was the aim of this study. The authors focused on two aspects...

ABSTRACT Plastic pollution is increasing and plastic waste usually ends in environment. Microplastics (MP) as insoluble and anthropogenic micropollutant is ubiquitous and its concentration is expected to increase in the environment. One of important sources are wastewater treatment plants, where...

Wastewater generated in oil production and refinery industries contains high levels of pollutions. Water from the oil production field is the largest source of wastewater in the oil production and refinery industry. It can cause environmental problems on a global scale due to its high volume and...

​The enzymatic fermentation of starch from non-edible sources using Aspergillus niger could help supplement the increasing glucose demand within the Nigeria food supply chain. Also, response surface methodology could help optimise the glucose production of starch hydrolysed from cocoyam tubers. In...

Industrial production brings serious Cr(Ⅵ) pollution problems, so as to explore new treatment methods for Cr(Ⅵ), In this paper, modified montmorillonite was prepared by modifying montmorillonite with starch and lanthanum nitrate, and its adsorption mechanism and effect on Cr(Ⅵ) were explored. The...

Plastic waste is harmful to the environment due to its long-term decomposition process. Plastic waste is made out of hydrocarbon polymers, its chain bonds do not naturally decompose physically, chemically, or biologically. The plastic waste generated in Indonesia reaches up to 175,000 tons per day...

The reductive gas composition produced by the reburning of sludge can reduce NOx in flue gases to N2, which provides a new idea for the study of gas denitration, and at the same time makes denitration by sludge reburning become an important part of gas denitration research. However, due to the...

The Maluku Islands (henceforth MI) are situated in the northeastern Indonesia. Ocean region off the central MI is pivotal as it provides a course for the Indonesian Throughflow (ITF) through the Lifamatola passage. However, sea surface dynamics off the central MI is unknown until recently due to...

This study evaluates the pyrolysis of sewage sludge until 960 °C using heating rates between 3 K/min and 12 K/min in a macro TG/EGA. Mass and energy balances and kinetic parameters are determined. Thermal decomposition is divided into a low temperature zone (until 550 °C to 590 °C), for...
