✦ Synopsis

An investigation was made on a way to put bean-curd refuse (okara) to practical use in moulding vessels and other utensils. The mixture of bean-curd refuse, pulp (®bres of paper) and calcium hydroxide in the ratios 100 : 10 : 5 (by dry weight) was suspended in 200 times its volume of water and heated at 50 to 80 °C for more than two hours. Some vessels or utensils were moulded from the residue of the ®ltered mixture and dried in a drying oven. The resulting products exhibited desirable characteristics Ð light, hard and waterproof, and had adequate strength for use for vessels such as gardening pots or dishes for serving food. Moreover, they degraded within about three months when buried underground. The products are not only suited to the practical use of bean-curd refuse but are also friendly to the environment.
