ALCIVAR-CEDENO, Ulbio et al. Analysis of Waste in the Production of Flour California Red Worm (eisenia foet) in Manabí Technical Universitypilot Plant. RTQ [online]. 2016, vol.36, n.3, pp. 281-295. ISSN 2224-6185.

The necessity for have efficient tools in the environmental assessment of production processesis treated in this paper. This work is related to a previous work made in the Technical University of Manabi, forprotein supplements production from unconventional raw materials, specifically Earthworm (Eisenia foetida)flour, using various ecotoxicological methods to evaluategeneratedwaste in pilot production, in order to contribute to compliance the environmental regulations. Liquid wastes generated in the production of earthworm flour were determined and evaluated under the following biological indicators: inhibition of seed germination, root growth in Lactuca sativa, acute toxicity in Eisenia foetida to determine the environmental toxicity of the production process. As result, the major environmental contamination that occurs during the process of obtaining meal worm (Eisenia foetida) is given in the cleaning process, sacrifice, washing and milling. The waste characterization allowed determining that they are domestic water and process water. The use of ecotoxicological bioassays described, that the sacrificialwater inhibit germination and root elongation, and they are classified as slightly toxic thewash waters cause sublethal effects.
