Recovery of essential nutrients from municipal solid waste – Impact of waste management infrastructure and governance aspects

Treatment technologies for urban solid biowaste to create value products: a review with focus on low- and middle-income settings

“…Besides reducing public health threats (Ahmad et al 2007) and environmental burden (Friedrich and Trois 2011), returning resource value of waste into the economy reflects the paradigm shift towards a circular economy focused on 'closing loops' through recovery, while at the same time considering new business opportunities and economic growth (Ghisellini et al 2016;Witjes and Lozano 2016). Biowaste treatment in a circular economy addresses resource scarcity, for instance the depleting nutrients stocks such as phosphorus (Zabaleta and Rodic 2015). It can also act as driving force for overall waste management when, for instance, the economic value of biowaste-derivedproducts incentivizes waste collection or the new revenue opportunities enhance financial sustainability of the system .…”

The role of management instruments in the diversion of organic municipal solid waste and phosphorus recycling

“…This analysis used a specified search string (see Supplementary Material 1), the snowball method using reference lists (Greenhalgh and Peacock 2005), Google ™ searches (for grey literature), and personal communication. Based on relevance, we selected 11 (Field et al 1984;Tiquia et al 2002;Michel et al 2004;Massé et al 2007;Marcato et al 2008;Andersen et al 2010;Banks et al 2011;Schievano et al 2011;Möller and Müller 2012;Pognani et al 2012;Zabaleta and Rodic 2015) existing peerreviewed studies, including one meta-analysis (Zabaleta and Rodic 2015) of nutrients and organic waste management processing, for information on losses of P within the biological treatment process. Additional grey literature studies were found for both Europe (Barth et al 2008) and Ontario (van der Werf 2013) concerning the distribution of end products.…”

“…Organic waste constitutes approximately 30%-50% of municipal solid waste streams in developed countries (Ponsá et al 2008;Fehr and Arantes 2015;Recyc-Québec 2015). Where conventional waste management is practiced, much of this organic waste is buried in landfills, incinerated (with the ash sent to landfill), or stabilized and used as landfill cover (Tsai 2008;Senthilkumar et al 2014;Metson and Bennett 2015a;Zabaleta and Rodic 2015). The disposal of organic waste in landfills is associated with greenhouse gas emissions and nutrient loading to waterways (Augenstein 1992;Bulkeley and Askins 2009).…”

Agricultural Waste

“…They found that using inoculated earthworms could improve the nutrient profile in MSW, which was effective to improve the plant growth, comparing to the process of composting only. Zabaleta and Rodic (2015) Bernstad Saraiva Schott and Cánovas (2015) estimated primary factors which influenced the changes in GWP-emission savings. Meanwhile, they found an effective method for comparing cross-study.…”
