For example, a waste oil recovery container 11 used for recovering waste oil such as used cooking oil or old engine oil after replacement of an automobile includes a plurality of waste oil absorbers 10 (3 in this embodiment) and a bag-shaped body 12. It is housed inside. The bag-shaped body 12 is made of material such as polyvinyl chloride, processed paper in which paper is coated with synthetic resin such as polyvinyl chloride, flexible sheet in which aluminum is deposited on paper or synthetic resin, or aluminum foil. , Has oil impermeability and oil resistance. The capacity of such a waste oil recovery container 11 is 500 ml for household use such as collecting used cooking oil such as tempura oil, and for collecting engine oil after replacement. When it is used for business purposes, it is possible to collect and collect about 2 to 5 liters.

FIG. 2 is a diagram for explaining a manufacturing process of the waste oil absorber 10 shown in FIG. As shown in FIG. 2 (1), the waste oil absorber 10 is made by crushing a milk carton or corrugated waste paper onto a mat 13 made of an oil permeable material such as a non-woven cloth such as a tissue. The absorbent material 14 made of granular pulp is thinly and flatly laminated, and the partition sheet 15 smaller than the mat 13 is mounted on the absorbent material 14 to form a laminated body 16. The partition sheet 15 is made of the same material as the mat 13.

As shown in FIG. 2 (2), the laminated body 16 formed in this manner is folded in three to form a triple structure, and the mat 13 has many perforations 17, which are fine cracks. It is formed. It has been confirmed by the present inventors that the perforation 17 has high absorption efficiency when it is formed in a unit area of 10 cm × 10 cm with a pitch of about 2 to 10 mm and a total length of about 5 to 200 cm. Has been. In addition, instead of the perforation, a fine needle-shaped object may be used to form a circular crack. In any case, it is important to form only the crack without opening it. As a result, it is possible to prevent the fine paper powder of the absorbent material 14 from scattering to the outside and to improve the absorption speed by the action of the capillary phenomenon.

As shown in FIG. 2C, the three-fold laminated body 16 thus formed is covered with the outer packaging sheet 30 to form the waste oil absorber 10. Both sides 18 and 19 and both ends in the circumferential direction of the outer packaging sheet 30 are doubly (see FIG. 1) sealed by thermocompression bonding, and substantially the same as the perforation 17 of the mat 13 shown in FIG. Similar perforations 21 are formed.
