“…The bagasse or cotton feedstock is higher in the recalcitrant components than rice straw which could hamper the degradation during composting. This is harmony with Hanc and Pliva (2013) and Hanc and Dreslova (2016), whose attributed the differences in the particle size distribution to the presence of components (e.g. branches) in garden feedstock, fibrous character of straw or dewatered digestate, which are more difficult to degrade, contributed to the high proportions of the coarser fractions.…”

“…Throughout the five experiments, a lot of different substrates and mixtures have been tested on their performance for worm cultivation. Similar substrates have been tested previously, Hanc et al, (2020) researched the feasibility of vermicomposting (with Eisenia andrei) of malting sludge in combination with straw pellets. The worms only grew when the malting sludge was mixed with at least 50% of pelleted straw (Hanc et al, 2020).…”

“…In addition, bulk density, pH, water holding capacity, heavy metal levels, nitrogen, phosphorus and potassium content are promoted by vermicomposting over traditional composting (Aslam, 2021;Geremu et al, 2020). Some recently studied substrates for producing earthworms include bakery industry sludge (Yadav & Garg, 2019), cattle solid wastes (Rini et al, 2020), pineapple waste (Zziwa et al, 2021), malting sludge (Hanc et al, 2020) and municipal solid waste (Ramprasad & Alekhya, 2021).…”

This report describes five experiments to observe the growth of Dendrobaena veneta and Eisenia fetida on substrates originating from Avebe (potato starch and protein producer), Holland Malt (maltings) or others ( kitchen and garden wastes). The substrates include Tarra (Avebe), Secondary food industry Sludge (Holland Malt and Avebe), Barley Dust (Holland Malt), Germinated Barley (Holland Malt), Bokashi (Jansen Wijhe), Potato Peels (van Vulpen voeders), vegetable fruit and garden waste (van der Wal and Ogar), Apple pulp (van Vulpen voeders), Champost (Koolen champignons CNN) and Carrot and Pumpkin Peels (van Vulpen voeders). The compost worms' growth was monitored for 4-6 weeks. The compost worms were able to convert the substrates into dry, light and powdery vermicompost high in nutrients and organic matter. The compost worms themselves increased in biomass and produced eggs. The protein content of the compost worms ranged between 57.1 and 68.3 % of DM, whereas the fat content ranged between 7.8 and 9.1% of DM. Tarra and Secondary food industry Sludge (Avebe) are suitable substrates for vermicomposting, when mixed with other substrates. Germinated Barley and Secondary Food Industry Sludge (Holland Malt) are less suitable for vermicomposting, due to substrate instability, even when mixed with other substrates. Additions of barley dust and chalk make the substrates' texture and composition more suitable for the worms to feed on.
