Survey of Possibilities for the Reduction of Operation and Management Costs for Salvinia molesta and Other Invasive Weed Species by Identification of Productive and Potentially Profitable Use of Biomass Utilizing ZERI Principles

Salvinia molesta has become a serious invasive weed in the Lower Colorado River from Blythe into Mexico. The Bureau of Reclamation and several partnering agencies have an active program to control and remove Salvinia. Current practice is to leave the wet plants on shore to dry and then bury the dessicated plants. Alternative uses for the plant biomass would be reduce disposal costs and potentially encourage a commercial harvest of the weed, freeing up resources now devoted to removal of Salvinia from the river.

been researched extensively. Potential uses of Salvinia obtained through reclamation are dependent upon bioaccumulation of chemicals and obtainable mass. The use of harvested Salvinia as a source for biogas digesters shows some potential. The use of harvestable dry mass of Salvinia is the bottlenecking factor for its use to create paper. Salvinia can be used as a cheap source of protein for animal and fish feeds but it is not determined weather it can completely replace protein in commercial feeds. Salvinia can also be composted for fertilization, primarily if there is bioaccumulation of nutrients from the water source. Upon review of the material it seems that there is potential use for Salvinia as an animal feed source for commercial industries such as agriculture and aquaculture.
