The present invention provides a lightweight molded article that is lightweight, excellent in water retention, strong, has good plant growth, and can be easily obtained at low cost from waste paper or rice straw. [Solution] Rice husk or sawdust or both powders and cement and water are added to the cut paper, kneaded, molded and dried, and the molded product is a flower pot, moss or plant cultivation box or It is characterized by being containers such as pots, moss plates, bricks, flower bed bricks, and vegetation slope construction spacers 1. Furthermore, the cutting paper is immersed in the rice straw fermentation liquid obtained by immersing rice straw or the cut rice straw in water and fermenting it, so that part of the cutting paper is dissolved, and the partially dissolved material is dehydrated and used. It is also what you do.
