Green sand moulding uses silica sand for metal casting. Silica sand mining and delivery to foundries destroy the ecosystem, making metal casting unsustainable. Due to increased sand-casting output and massive civil buildings in India, the silica sand supply is declining. The depletion and shortage...

One of the biggest environmental issues has been the use and disposal of traditional fossil-based plastic, which is not biodegradable and uses a lot of energy in its production. Poly lactic acid (PLA) has received a lot of attention as an environmentally friendly substitute due to the fact that it...

The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes a crisis in the waste disposal and thereby contributes to environmental issues. Recycling concrete manufacturing waste materials not only offers...

Owing to increased population, the ground water pollution and disposal of solid waste from the domestic, commercial and the industrial sources has become higher. Mainly, leachate from sanitary landfills increase the ground water pollution and disposal of solid wastes may produce the emission of...

In recent years there has been a heightened concentration on the industrial subsectors that are the primary contributors to environmental pollution. Filler materials made from mineral limestone, which is composed of calcium carbonate (CaCO3), are utilized in the production of polymer composites in...

The discharge of wastewater from net washing is one of the most significant problems in the marine ecosystem because of its high organic and saline content. Sea water quality is deteriorated every day due to the high amount of organic matter produced in the aquaculture sector. The aim of this study...

With an estimated volume of 162 thousand metric tonnes in 2020, India is the world's largest producer of tamarind. The country is home to a number of tamarind species, and production is spread out across the country. Farmers and agro-industries continue to encounter numerous challenges in the...

Tamarindus indica shell biochar is employed as an alternate adsorbent precursor for the removal of heavy metal ions from aqueous solutions. It investigated the Tamarindus indica shell biochar's capacity to absorb chromium (Cr), copper (Cu), and Lead (Pb). This study showed the extensive explored how...

Azo dye is a synthetic aromatic dye which are direct dye frequently used in textile industry to colour fibres. It also contributes to the damage of the environment. This study examines the adsorption biochar made from Annona reticulata to remove azo dye from textile wastewater. To improve the...

Olive mill wastewater (OMWW) contains many phenolic compounds that if discharged without proper treatment, may lead to substantial risks to human health and deterioration of the environment and aquatic systems. In this study, an attempt was made to produce activated carbon from Rice Husk (RH). The...

In concrete industry, the use of concrete solid wastes is becoming further common since it can minimize associated costs and environmental implications. The current research looks at how concrete performs when polypropylene (PP) plastic, produced from pollution garbage items, is used as a partially...

Oil Palm Kernel Shell (OPKS) is a residue of the palm oil extraction process, which has good characteristics for the production of activated carbon (AC). Colombia ranks fourth in the world in palm oil production and it is estimated that in 2019 the amount produced of OPKS was approximately 336000...

Water waste management is one of the major hassles which is faced by the majority of industries. The industries let the wastewater into flowing streams or rivers near them, polluting the water resources in that locality. To prevent and safeguard the water resources, the government has given much...

The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...

People are prompted to complain about air pollution by offensive odours. They can produce psychological consequences, such as nausea, headaches, lack of appetite, breathing difficulties, and various adverse reactions in some circumstances. Among various industries, the dairy industry emits the most...

Urbanized areas groundwater vulnerability and contamination are serious issues that require due attention. There are other models, notably the DRASTIC models employed to assess the vulnerability of groundwater. In a modified version of the DRASTIC model known as anthropogenic influence was...

Dinitrobutylphenol is a toxic and resistant pollutant that pollutes the environment by producing toxins and chemical wastewater. Present paper aims to study the efficiency of the magnetic particles of walnut hard shell ash as a cheap and bi-compatible adsorbent for the removable of DNBP from aqueous...

The coconut shell-derived biochar was employed in this study to remediate Remazol Black B from aqueous solutions. For efficient dye remediation, preliminary batch investigations focused on adjusting temperature, biochar dosage, initial dye concentration, and pH. The results shown that dosage of...

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...

Drought is a disastrous natural phenomenon. It is generally viewed as a sustained and regionally extensive occurrence of below average natural water availability either in the form of rainfall, river runoff or groundwater. Drought is defined based on different factors and generally assessed in...

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...

Growing environmental awareness coupled with stricter regulations has pushed various industries to look for appropriate technologies to treat wastewater. Natural coagulants have recently been used as part of water and wastewater technologies due to their performance, cost-effectiveness when compared...

Unqualified treatment of the discharge of wastewater contains a large number of nitrogen and phosphorus and other nutrients, such wastewater into the water environment is easy to lead to eutrophication of water bodies, and cause harm to human health. In order to prepare a cost-effective, efficient...

An approach was used in this study to relate the predicted and calculated water quality index (WQI) of the Brahmani River. The WQI was predicted using an artificial neural network (ANN) tool, and the weighted Arithmetic Index technique was used to calculate the WQI (WAI). The WQI is calculated using...
