Pivotal role of municipal wastewater resource recovery facilities in urban agriculture: A review

Abstract

Urban agriculture provides a promising, comprehensive solution to water, energy, and food scarcity challenges resulting from the population growth, urbanization, and the accelerating effects of anthropogenic climate change.Their close access to consumers, profitable business models, and important roles in educational, social, and physical entertainment benefit both developing and developed nations. In this sense, Urban Water Resource Reclamation Facilities (WRRFs) can play a pivotal role in the sustainable implementation of urban agriculture. Reclaimed water as a recovered resource has less supply variability and in certain cases can be of higher quality than other water sources used in agriculture. Another recovered resource, namely, biosolids, as byproduct from wastewater treatment can be put to beneficial use as fertilizers, soil amendments, and construction material additives. The renewable electricity, heat, CO 2 , and bioplastics produced from WRRFs can also serve as essential resources in support of urban agriculture operation with enhanced sustainability. In short, this review exhibits a holistic picture of the stateof-the-art of urban agriculture in which WRRFs can potentially play a pivotal role. Practitioner Points• Reclaimed water can be of higher quality than other sources used in urban agriculture.• Biosolids can be put to beneficial use as fertilizers, soil amendments, and construction material additives.• The renewable electricity, heat, CO 2 , and bioplastics produced can also serve as essential resources in support of urban agriculture.

Review on food waste valorisation for bioplastic production towards a circular economy: sustainable approaches and biodegradability assessment

“…Polymers that exist naturally and are directly recovered from biomasses are collagen, casein, cellulose and starch; polymers formed through biobased monomeric polymerization processes along with fermentation, such as PLA and product polymers obtained through the microbial metabolization products of microbes are all included in the category of biobased materials specically meant for food packaging (e.g., PHA). 32 Nearly all food waste items containing enough carbon and nitrogen can be turned into biopolymers with the proper techniques.…”

Analisa Faktor Yang Mempengaruhi Masyarakat Di Wilayah Berkembang Dalam Berpartisipasi Dalam Pengolahan Sampah Berbasis Black Soldier Fly (Studi Kasus: Kecamatan Pantai Labu, Sumatera Utara)

“…Masalah lingkungan terkait dengan tingkat dampak lingkungan yang diakibatkan dari pengelolaan sampah yang tidak baik, termasuk kontaminasi air, udara, dan tanah (Rajmohan et al, 2019;Septiariva & Suryawan, 2021), dan juga dapat menjadi jalur penyebaran bakteri (Anand et al, 2022). Dampak lain juga terkait dengan Tempat Pemrosesan Akhir (TPA), seperti berkurangnya lahan, penyebaran organisme patogen, timbulnya bau yang tidak diinginkan serta kontribusi terhadap emisi gas rumah kaca (Wang et al, 2022). Metode pengelolaan sampah menggunakan TPA ini membutuhkan waktu yang lama sebelum sampah terurai sepenuhnya (Ayilara et al, 2020).…”
