“…In comparison, the protein content of the (left over) worms was 61.6% for TSS I and 57.1% for TARRA2 II. The percentage of protein content found in the worms of between 57 and 68 % is in range with literature (Gunya et al, 2021;Parolini et al, 2020;Sogbesan & Ugwumba, 2008). The fat content of worm meal ranges between 5 to 20 % of dry matter.…”

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.

“…This results in a reduction in pig manure organic matter, new worm biomass and vermicompost, which can be used as a fertilizer (Atiyeh et al, 2001;Chan & Griffiths, 1988;Elissen et al, in preparation)). Worm biomass can be used as fish bait or as part of an aquaculture or poultry diet (Gunya & Masika, 2021;Musyoka et al 2019;Parolini et al, 2020). Of course, when using worm biomass as feed it is important to check whether heavy metals or other toxic compounds (or pathogens) from waste streams are accumulated in the worms themselves.…”

In the Netherlands, there are surpluses of pig manure, which currently represent a negative value.At the same time, pig manure contains valuable ingredients for the production of biomass. These ingredients can be potentially be converted to feed and vermicompost by earthworms, such as Eisenia fetida and Dendrobaena veneta. Thereby producing alternative protein sources for feed and alternatives for artificial fertilizer. The number of feasible business cases in which the pig manure is upgraded has so far been limited. This is due both to the efficiency of the technologies used and the legislation and regulations related to the pig manure. This report explores the profitability potential of vermicomposting solid pig manure by individual pig farmers.Samenvatting In Nederland is een overschot aan varkensmest, dat momenteel een negatieve waarde heeft.Tegelijkertijd bevat varkensmest waardevolle ingrediënten voor de productie van biomassa. Deze ingrediënten kunnen mogelijk worden omgezet naar voer en vermicompost bij aardwormen, zoals Eisenia fetida en Dendrobaena veneta. Hiermee kunnen alternatieve eiwit bronnen voor voer en alternatieven voor kunstmest worden geproduceerd. Het aantal haalbare business cases, waar varkensmest wordt opgewaardeerd, is tot nu toe gelimiteerd. Dit is zowel door de efficiëntie van de gebruikte technologieën, als wet en regelgeving rondom varkensmest. Dit rapport verkent het winstgevendheidspotentieel van het vermicomposteren van varkensdrollen door individuele varkenshouders.

“…Eisenia fetida is well known from compost heaps where it strongly affects enzyme activity resulting in the acceleration of the composting process ( Aira, Monroy & Domínguez, 2006 ). This species is very active and reproduces rapidly resulting in fast population growth ( Gunya & Masika, 2022 ). However, E. fetida also lives in natural habitats in southern Europe and increasingly also in eastern China, in particular close to urban areas, where it colonizes forest floors as epigeic species ( Pižl, 2002 ; Huang, Zhang & Gao, 2003 ; Lu & Lu, 2015 ; Koubová et al, 2015 ; Geraskina, 2016 ).…”

Earthworms neutralize the influence of components of particulate pollutants on soil extracellular enzymatic functions in subtropical forests

Human activities are increasing the input of atmospheric particulate pollutants to forests. The components of particulate pollutants include inorganic anions, base cations and hydrocarbons. Continuous input of particulate pollutants may affect soil functioning in forests, but their effects may be modified by soil fauna. However, studies investigating how soil fauna affects the effects of particulate pollutants on soil functioning are lacking. Here, we investigated how earthworms and the particulate components interact in affecting soil enzymatic functions in a deciduous (Quercus variabilis) and a coniferous (Pinus massoniana) forest in southeast China. We manipulated the addition of nitrogen (N, ammonium nitrate), sodium (Na, sodium chloride) and polycyclic aromatic hydrocarbons (PAHs, five mixed PAHs) in field mesocosms with and without Eisenia fetida, an earthworm species colonizing forests in eastern China. After one year, N and Na addition increased, whereas PAHs decreased soil enzymatic functions, based on average Z scores of extracellular enzyme activities. Earthworms generally stabilized soil enzymatic functions via neutralizing the effects of N, Na and PAHs addition in the deciduous but not in the coniferous forest. Specifically, earthworms neutralized the effects of N and Na addition on soil pH and the effects of the addition of PAHs on soil microbial biomass. Further, both particulate components and earthworms changed the correlations among soil enzymatic and other ecosystem functions in the deciduous forest, but the effects depended on the type of particulate components. Generally, the effects of particulate components and earthworms on soil enzymatic functions were weaker in the coniferous than the deciduous forest. Overall, the results indicate that earthworms stabilize soil enzymatic functions in the deciduous but not the coniferous forest irrespective of the type of particulate components. This suggests that earthworms may neutralize the influence of atmospheric particulate pollutants on ecosystem functions, but the neutralization may be restricted to deciduous forests.
