Urbanization exacerbates water scarcity by increasing demand while reducing the availability of natural water reserves. Food waste is another critical issue that affects urban sustainability. Recycling treated greywater presents a sustainable alternative, particularly for irrigation purposes. This study evaluated the effectiveness of a media blend of spent coffee grounds and date seeds (1:2 ratio) for cultivating five ornament...

Biochar has received significant interest as a soil amendment but its relative performance to addition of high-quality soil is not well assessed. This study compared different loadings of cabbage-waste biochar produced at 360 °C against potting mixture (PM) as amendments to enhance basil ( Ocimum basilicum ) growth in sandy soil. Pot tests for six conditions of biochar, PM or their blend were tested at both 2% or 6% loading, p...

Large-scale production of single-cell protein (SCP) has the potential not only to solve some of the food insecurity and water scarcity crises that plague a significant portion of our world today but also holds the promise to reduce the cost associated with the treatment of industrial and agricultural wastewater. Resource recovery of SCP from organic waste by microbes like yeast and microalgae is commonly documented. However, r...
