The previous chapters covered how stabilisation, drying, and pathogen reduction of faecal sludge (FS) can be achieved with different treatment technologies, and combinations of these various technologies. Each treatment technology results in endproducts which need to be further treated, disposed of, or harnessed for some type of resource recovery. Endproducts, for example dried or partially dried sludge, compost, leachate, and biogas, each have an intrinsic value, which can turn treatment from merely a method for environmental and public health protection to resource recovery and value creation. This chapter focuses on the endproducts produced from the various FS treatment processes, addresses potential difficulties and restrictions with their enduse, and discusses additional steps that can or should be applied to turn a treatment endproduct into a valuable asset.
