Lignocellulosic biomass is the most abundant cheap resource produced from agriculture and forest residues. Among several thermochemical pretreatments reported in the literature, Ammonia Fiber Expansion (AFEX) pretreatment uses ammonia that can be recovered and re-used benefiting the environment. Ammonia helps open up the complex cell wall by cleaving the ester linkages and increasing the digestibility during enzyme hydrolysis and rumen in the animal gut. The lignin solubilized by ammonia during AFEX pretreatment is partially relocated to the surface of the biomass, while it is released to act as a natural binding when densifying the biomass. The AFEX pellets have a bulk density comparable to corn, can be stored in grain elevators, and can be used for diverse applications, such as feedstock for biofuels, animal feed, anaerobic digestion, and producing biocomposite materials. A local biomass pretreatment depot (LBPD) will help produce the AFEX pellets near the location where the feedstocks are produced and transported using trucks or rail carts. This approach will help overcome the logistic issues of transporting and storing biomass and sold as a commodity product that will enable the biochemical platform and biobased economy.

This paper introduces orange waste as a promising substrate for microorganism fermentation to produce single cell proteins (SCP) which can be used for animal feed or human food. Firstly, the nutrition composition and physical features of orange waste, the composition of auxiliary material and the biomolecular composition of microorganisms are collected for analysis. Secondly, available data on fermentation conditions and parameters, possible application in animal feeds and the impact on animals are summarized; to demonstrate the feasibility of fermented orange waste as animal feed. Furthermore, the economic benefits and costs of SCP produced from fermented orange waste are discussed. Therefore, the development of fermented orange waste as animal feed has been comprehensively and systematically analyzed, laying a solid foundation for future commercial applications in the Three Gorges Reservoir Region.
