Testing adsorption properties of natural zeolites for nutrients in wastewater

(Corresponding) Ravina M., Marotta E., Zanetti M.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Low-cost and efficient removal of nutrients in decentralized wastewater treatment plants is still challenging. The installation of supplementary adsorption systems may, in some cases, be appropriate. This work focused on two types of untreated natural zeolites, clinoptilolite and chabasite, with...Read more

(Corresponding) Rollon A., Lingating R., Pimentel J., Areo H., Ibias K., Mamugay R., Dela Cruz I.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
For treatment of high-strength domestic wastewater, this study explores a fed-batch bioprocess system consisting of anaerobic (AD), aerobic (AER) and anoxic (ANX) processes in this order and each run at 24 h hydraulic retention time (HRT) and 0.8 g COD/L/d in the first bioreactor. The largest COD...Read more

Development of a Standardized Greenhouse Gas Quantification Template for the Philippine aviation industry

(Corresponding) Del Rosario B., Ballesteros F.
Topic: 
5. ENVIRONMENTAL MANAGEMENT AND POLICY
International aviation contributes 2.1% of global carbon emissions, with Philippine air transport emitting 0.712 million metric tonnes of CO₂e. In response, a greenhouse gas quantification template (GHGQT) was developed to enhance industry-wide emissions monitoring, using established methodologies...Read more

Use of waste dealuminated metakaolin in alkali-activated cement mixes

Elsebaei M., (Corresponding) Mavroulidou M., Micheal A., Centeno M., Shamass R., Rispoli O.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
This paper explores the feasibility of using dealuminated metakaolin (DMK), a hazardous by-product of the alum industry, in alkali-activated cement (AAC) mixes, as an outlet for this voluminous hazardous waste, alternative to landfilling. After reviewing global DMK waste manage-ment practices and...Read more

Feasibility of peat soil stabilisation with solid waste material inclusions and biocementation treatments

(Corresponding) Mavroulidou M., Gunn M., Joshi S., Sanam I., Murad M., Garelick J.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
This paper studies the stabilisation of a peat railway embankment foundation soil from East Anglia, UK, using solid waste material inclusions and biocementation treatments. Peats are weak, high water content soils which lead to construction problems, due to the high water content and poor...Read more

Novel Heterostructured Holey Graphene-NiTiO3/TiO2 Nanocomposite Enabled Photocatalytic Mixed Matrix Membranes for Effective Antibiotics Removal

Aboukhater A., (Corresponding) Kumar M., (Corresponding) Hasan S.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Antibiotics are widely used in healthcare, agriculture, and animal husbandry, contributing to their increased presence in water sources through wastewater, agricultural runoff, and improper disposal. This leads to antibiotic-resistant bacteria and poses risks to both ecosystems and human health...Read more

Impacts of Quarry Blasting on Water Sustainability: Assessment of Social Acceptability in the Municipalities of Camalig and Guinobatan, Albay

(Corresponding) Gabuco K., Clemente E.
Topic: 
5. ENVIRONMENTAL MANAGEMENT AND POLICY
Quarry blasting is perceived as a risk to groundwater sustainability by rural communities in Camalig and Guinobatan, Albay, Philippines. The Ibalong Resources and Development Corporation (IRDC) has conducted blasting operations since 2013 across three quarry sites. As many residents rely on deep...Read more
