A transport system can include a first chamber having a body that is configured to fully enclose a biodegradable container placed within the first chamber, the biodegradable container having food waste therein, and the biodegradable container being sealed from the ambient environment, and a disinfection system being configured to disinfect an object placed within the body. The transport system can include a second chamber having a composting system, the composting system being configured to begin to compost an object placed within the second chamber, and an enclosure that houses the first chamber and the second chamber. The first chamber, and the second chamber can be configured to be placed within a cargo space of a vehicle.

The present invention relates to a polyphosphoric acid calcium magnesium fertilizer prepared by using phosphoric acid and phosphorus tailings as raw materials and a preparation method therefor. The polyphosphoric acid calcium magnesium fertilizer is prepared by using phosphorus tailings and phosphoric acid as raw materials. Based on P.sub.2O.sub.5, MgO and CaO, in the polyphosphoric acid calcium magnesium fertilizer: total phosphorus is 50-68%, effective phosphorus is 47-66%, total magnesium is 5-18%, effective magnesium is 4-15%, total calcium is 11-20%, effective calcium is 10-18%, and all are expressed in mass percentage. Based on P.sub.2O.sub.5, the polymerization rate of the polyphosphoric acid calcium magnesium fertilizer is ≥50%. The present invention also provides a preparation method for the fertilizer. The phosphorus in the product prepared by the invention has sustained-release properties. The fertilizer is well suited for crops requiring large amounts of calcium and magnesium.

There is provided herein a granule comprising Polyhalite and phosphogypsum, in a ratio of between 40:60 to 60:40, respectively.

A method for producing potassium chloride granular materials from a crystalline potassium chloride raw material, wherein, before the granulation process, the potassium chloride raw material is treated with at least one alkali metal carbonate and at least one hydrogen phosphate additive in the presence of water. The alkali metal carbonate is anhydrous sodium carbonate, sodium carbonate monohydrate or sodium carbonate decahydrate.
