The present disclosure relates to a method of producing bioplastic pellets using livestock manure, the method including steps of: making a first mixture livestock manure, sawdust, a microbial medium and a microbial preparation; (2) making a fermentation product by stirring the first mixture; (3) making an aged product by aging the fermentation product; (4) making a dried product by drying the aged product; (5) making compost powder by crushing the dried product; and (6) mixing the compost powder, synthetic resin, a binder, a dispersing agent and a slip agent together to obtain a second mixture, and cutting the second mixture into pellets during extrusion. The method has an advantage in that it is possible to improve processability by reducing the water content of decomposed livestock manure containing a lot of water and to improve mechanical properties.

The present invention provides a method of reducing and controlling a hazardous substance in a process of high-value biological conversion of an urban organic waste. The method includes: 1) mixing a sludge, a first urban organic waste and an organic acid with water for acclimation to obtain an acclimatized sludge; 2) stage 1 of biological conversion: mixing the acclimatized sludge with a second urban organic waste to perform anaerobic culture; 3) stage 2 of biological conversion: adding nitrate and bacteria to continue anaerobic culture so as to obtain an organic acid. In the present invention, sludge microbes are acclimatized and then added to high-value chemicals such as acetic acid, propanoic acid and lactic acid prepared in biological conversion of the urban organic waste and then added with bacteria. Thus, by controlling pH value, microbe addition amount and nitrate concentration, the unfavorable effect of the antibiotics and heavy metal ions.

There is provided microbial compositions and methods for producing thereof and use of compositions thereof in treatment of contaminated soil, water, and/or surfaces. In one aspect, there is provided method for reducing microbial contamination of a microbial contaminated body, the method comprises: inactivating resident vegetative microbiology from an extract obtained from a contaminated of body to inactivate the resident vegetative microbiology in the extract, selecting one or more soil-based microbes suitable for growth in the contaminated body, growing the one or more soil-based microbes with the inactivated extract to allow the one or more soil-based microbes to adapt to the inactivated extract, releasing the one or more soil-based microbes into the contaminated body where the one or more soil-based microbes dominate and reduce microbial contamination of the microbial contaminated body.
