“…This reduces labor requirements and the time needed for the operation. Finally, pellets -depending on the binding agent and densification -can more quickly or more slowly release nutrients and thus meet crop requirements, and minimize nutrient loss through (for example) leaching after land application (Nikiema et al 2013;Hettiarachchi et al 2016). This implies that pelletization can help to achieve higher fertilizer efficiency, and long-term (residual) benefits, as opposed to non-pelletized co-compost.…”

Resource Recovery and Reuse (RRR) is a subprogram of the CGIAR Research Program on Water, Land and Ecosystems (WLE) dedicated to applied research on the safe recovery of water, nutrients and energy from domestic and agro-industrial waste streams. This subprogram aims to create impact through different lines of action research, including (i) developing and testing scalable RRR business models, (ii) assessing and mitigating risks from RRR for public health and the environment, (iii) supporting public and private entities with innovative approaches for the safe reuse of wastewater and organic waste, and (iv) improving rural-urban linkages and resource allocations while minimizing the negative urban footprint on the peri-urban environment. This subprogram works closely with the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP), United Nations University (UNU), and many national and international partners across the globe. The RRR series of documents present summaries and reviews of the subprogram's research and resulting application guidelines, targeting development experts and others in the research The authors Dr. Josiane Nikiema is a senior researcher at the International Water Management Institute (IWMI) and is based in Accra, Ghana. She has a PhD in chemical engineering from the Université de Sherbrooke, Canada. Her fields of expertise include domestic wastewater treatment and reuse, recovery of nutrients and organic matter from fecal sludge and organic solid waste, and testing business models for safe resource recovery and reuse. Dr. Olufunke O. Cofie is a principal researcher with a background in soil science. She heads IWMI's West Africa office in Accra, Ghana, and has worked over the past 15 years on the interface of sanitation and agriculture. Mr. Robert Impraim has an MSc in crop science and was a research officer for recycling and reuse at IWMI's Ghana office. He is currently a PhD student at the University of Melbourne, Australia. Mr. Eric G. Nartey has an MSc in environmental science. He is a research officer for recycling and reuse at IWMI's Ghana office. Mrs. Nilanthi Jayathilake has an MSc in environmental engineering and management. She is a research officer for septage management and reuse at IWMI headquarters in Colombo, Sri Lanka.

“…These fertilizers were mixed with gamma-radiated starch or pre-gelatinized starch (3%), and finally pelletized to reduce dusting risks, reduce the volume, and to make fertilizer more homogenic so that its application will be more accurate. Details of the process are described by Nikiema et al [8]. Mineral fertilizer (NPK), poultry manure (PM), and ACARP commercial compost (AC) were purchased from the local market.…”

Fecal sludge (FS) contains a significant amount of plant nutrients. FS (treated/untreated) has been used as soil ameliorant in several countries. Use of FS-based compost on lettuce may meet reservations due to possible microbiological contamination. The objectives of this research are: (1) To determine the fertilizer value of different formulations of sawdust and fecal sludge compost (SDFS) pellets, and (2) to compare the effect of these SDFS formulations with poultry manure, commercial compost, mineral fertilizer, and non-fertilization on lettuce cultivation. The SDFS products were made by enriching, and pelletized with ammonium sulphate, mineral-NPK, or ammonium sulphate + muriate of potash + triple superphosphate. Lettuce was cultivated in a greenhouse and an open field. The result showed that the saleable fresh weight lettuce yield obtained from all SDFS pellets with/without enrichments were higher than those obtained from commercial compost, poultry manure, mineral fertilizer, or no fertilizer. Cultivation in the open field gave higher yields than those in the greenhouse. No helminth eggs were detected in composts or lettuces. Some fecal coliforms were detected in lettuces fertilized with almost all fertilizers tested, including NPK and non-fertilized control. A properly treated fecal sludge-based fertilizer can be a sustainable solution for lettuce production, which helps urban and peri-urban agriculture.

Faecal sludge (FS) contains a significant amount of plant nutrients. After drying and composting, FS has been used as soil ameliorant in several countries. Use of FS-based compost on lettuce may meet reservations due to possible microbiological contamination. The objectives of this research are: (l) to determine the fertilizer value of different formulations of sawdust and faecal sludge compost (SDFS) pellets, (2) to compare the effect of these SDFS formulations with poultry manure, commercial compost, mineral fertilizer and non-fertilization on lettuce cultivation. The SDFS products were made by enriching and pelletized with ammonium sulphate, mineral-NPK or ammonium sulphate + muriate of potash + triple super phosphate. Lettuce was cultivated in a greenhouse and in an open field. The result showed that the fresh weight obtained from all SDFS pellets with/without enrichments were higher than those obtained from commercial compost, poultry manure, mineral fertilizer or no fertilizer. Cultivation in the open field gave higher yields than those in the greenhouse. No helminth eggs were detected in composts or lettuces. Some faecal coliforms were detected in lettuces despite fertilization treatments. A properly treated fecal sludgebased fertilizer can be a sustainable solution for lettuce production which helps urban and periurban agriculture.
