A resin particle is provided, in which a mass loss rate after being immersed in distilled water at 70°C for 14 days is less than 10%, and in which a mass loss rate after being left in a compost at 55°C for 14 days is 90% or more, the compost having nitrogen of 1.3 mass%, phosphoric acid of 0.5 mass%, and potassium of 2.9 mass% with respect to a total amount of the compost, and the compost having a carbon-nitrogen ratio (C/N ratio) of 25.
The present invention provides an attracting tool that is convenient, inexpensive, and useful for hunting. The present invention provides an attracting tool comprising an exothermic composition and an attractant, the exothermic composition containing an oxidation accelerator having an iodine adsorption number of not more than 700 g/kg, an oxidizable metal powder, and water, wherein at least the exothermic composition is housed in an air-permeable container bag.

Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. High solids concentrations in the feedstock stream can be obtained without significant impact on the feedstock stream stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The subsequent syngas produced from this material can be used to produce a wide range of chemicals.
