Slurries are a problem for the food-producing industry. They are comprised of solid and liquid wastes which must be precipitated and packed in polymers, and then disposed of in special landfills. A package of chemical substances (TCAS-CATA) has been developed to control the smell of this type of material. However, questions arose as to whether it would have any effect on nutrient bioavailability after eliminating the odors. To this end, slurries from animal processing plants were treated with TCAS-CATA in different conditions, and the parameters of this resulting solution were measured. Our results indicate that the catalyst can increase 100% nitrogenated compound concentration (400 mg/L of nitrites and 250 mg/L of Nitrate). This nutrient liberation depends on the slurry source, i.e., slurries with shells generate fewer nitrogenated compounds, but deliver more calcium to the solution. The solution also generates germination in some seed types and can stimulate development in some types of plants. Finally, the catalyst reduces odor 100% without reducing the capacity of the slurry to deliver nutrients. Our data suggest that TCAS-CATA may be catalyzing the bioavailability of the compound from the slurry without requiring microbiological processes, which will reduce odor and permit the use of this slurry as a biological remediation, similar to what is achieved in composting systems, but without the associated thermophilic processes. Future studies will allow for more knowledge of the mechanism and handling industrial material for agricultural processes.

Fish stranding or beaching is an infrequent but recurring phenomenon on the Chilean coastline and generates a serious public emergency. This phenomenon has been significantly reported around the mouth of the Laraquete River in Arauco, generally associated with water temperature changes and creating major environmental and public health problems due to the amount of organic matter deposited and outgassing from decomposition. This material is removed and taken to specialized landfills at a high cost, which merely transfers the problem without fundamentally solving it. Recently a product has been developed which appears capable of catalyzing organic material without the need for bacterial fermentation and increasing the bioavailability of soil nutrient materials. We evaluate this by using the product at the recommended concentration and doing on-site measurements of nitrites, nitrate, nitrogen, and phosphate levels. These showed, that after a 12-hour incubation period, the compounds increase, and organic material releases these compounds into a nutritious mud or organic compost. The smell was also evaluated as an indication of decomposition processes, with no changes recorded. The catalyzed material was transported to a farm site, mixed with low-quality soil, and subsequently planted with oats, reporting an output of over 90% in the soil treated with the catalyzed material. Health authority reviews raised no reports about odors. This data indicates that the product can release nutrients into the mud, generating organic compost, which can used for fertilizer in agricultural work. Future reports can indicate how this allows for new organic waste management strategies.
