The abandoned natural materials, including citrus extraction remnant, rice hull, beer and baekseju remnant, green tea remnant, and food by-product can be collected for free to make pulp molds. Many agricultural by-products are illegally incinerated or landfilled without disposing, and this leads to environmental destruction, such as particulate matter and forest fire. NANU collects abandoned natural materials for free to reduce the use of pulp mold, deliver the characteristics of natural materials, and increase bulk and water resistance. Extracts can be mixed with existing wood pulp to reduce the use of pulp mold, deliver the characteristics of natural materials, and increase bulk and water resistance. All pulp molds are made by extracting natural materials, and they are fully biodegradable
