TAILIEUCHUNG - Industrial Hemp (Cannabis sativa L.) as a Papermaking Raw Material in Minnesota: Technical, Economic, and Environmental Considerations

Some energy crop species are rich in toxic chemicals (such as allelochemicals in Jatropha). These toxic oilseed crops can enter the food chain in many ways. Research studies on the toxicity have highlighted the potential negative impacts on the ecosystem, including other plants that might grow in the vicinity. Pesticides impact the environment at several levels (from production of fertilizers to cultivation of energy crops). Studies show that the environmental footprint is comparatively larger during the cultivation process. Thus, a detailed analysis is required to quantify this criterion. The environmental impact can be calculated by using determining the toxicity of the pesticides used and the amount used to protect crops from natural field diseases and weeds. The amount of pesticides used or present in the environment can differ with the type of crop, the application procedure and the type of pesticides used. . | Industrial Hemp Cannabis sativa L. as a Papermaking Raw Material in Minnesota Technical Economic and Environmental Considerations1 by Jim L.
