Recently, the application of excreta-based fertilizers has attracted attention due to the strongly increasing prices of chemically produced fertilizers. Faecal sludge from on-site sanitation systems is rich in nutrients and organic matter, constituents which contribute to replenishing the humus layer and soil nutrient reservoir and to improving soil structure and water-holding capacity. Hence, it represents an important resource for enhancing soil productivity on a sustainable basis. However, there is little in the scientific literature about the performance of treatment technology allowing recovery of nutrient resources from human waste. This paper reviews the state of knowledge of different processes that have been applied worldwide. Their pathogen removal efficiency as well as nutrient and biosolids recovery performances are assessed. The chapter outlines the gaps in research for further development.

Waste management strategies such as anaerobic digestion and composting produce bio-based fertilizer products that could be applied to agricultural soil. Although multiple modelling software tools are available to simulate the environmental effect of fertilizer application to the soil, these models do not allow specification of emerging bio-based fertilizer types. Moreover, mathematical process models exist that allow optimizing the operational settings of waste management processes in order to produce an optimal bio-fertilizer quality adjusted to the local market needs. If an integrated tool would be available that couples process modelling to watershed modelling, the valorization chain could be simulated as a whole, i.e. the bio-fertilizer type and composition could be adjusted to the local watershed and environmental impacts of bio-based fertilizer production and application could more easily be assessed and controlled. The availability of such integrated tool may as such allow for improved decision and policy making regarding bio-fertilizer production and application with environmental benefits as a result.

To achieve higher standards of sustainability, Pakistan has to shift towards the adoption of the Circular Bio-Economy (CBE) approach in its agriculture sector. However, to aid this transition, the determination of a sustainable waste management technology and supporting strategies is very essential. For this purpose, a hybrid methodology based on fuzzy Strength, Weakness, Opportunities, and Threats (SWOT) and fuzzy Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) is developed. The fuzzy approach used in both the cases is to address any sort of ambiguity during the decision-making process. From the fuzzy SWOT analysis, the decision-makers allocated the most importance to the “ease of adoption” criteria, among the list of internal factors. Whereas, from the list of external factors, the most importance was allocated to the “price competitiveness with respect to fossil feedstock” criteria. Also, composting and anaerobic digestion are considered to be the most sustainable technologies for valorizing the agricultural waste of Pakistan. However, composting showcases more opportunities for its adoption as compared to anaerobic digestion. Whereas, results from fuzzy TOPSIS suggest the provision of financial support to both the local farmers and investors to be the top-ranked strategy for the successful implementation of the CBE approach.

The aim of this guide is to facilitate the utilization of Black Soldier Fly (BSF) as an alternative protein and fertilizer source, contributing to employment generation and poverty reduction. It is designed to support farmers, small and medium enterprises (SMEs), Extension Agents, and other stakeholders in acquiring the necessary knowledge and skills to engage in BSF farming as a viable business opportunity. Serving as an all-encompassing guide, it systematically outlines the ‘how’ and ‘why’ behind each stage of the BSF production cycle, starting from initial startup (point zero) to the successful harvesting phase. The manual also delves into the science of BSF farming, elucidates the steps for establishment, covers best practices, and provides insights into potential challenges within the production chain, along with strategies for ensuring the sustainability of the BSF enterprise.
