            The study has been undertaken to assess the effectiveness of using old and spoiled milk as raw material in the production of natural glue.  Specially, it attempted to answer the following questions: Can old and spoiled milk be combined with other raw materials to produce strong natural glue? What is the degree of acceptability of the glue made out of old and spoiled milk to consumers in terms of : Appearance, Viscosity, Smell and Adhesive strength? Is the produced natural glue cheaper than the commercially available glue? Is there a significant difference on the acceptability of the products in terms of the mentioned variables?

The study dealt with the creations of a domestic product out of old and spoiled milk. Other necessary raw materials of minimal proportions were used to bring about the desired product.  Results of the study were delimited to the feasibility of the external use of the produced natural glue which has been tested by consumers via the consumer acceptability survey. It was extended by comparing the cost of product of the natural glue to its commercial counterpart  through cost benefit analysis.

The material's needed in the production of the natural glue are as follows;               500mL oil or spoiled milk, 15 mL white vinegar, 30 g baking soda, 100 distilled water.

It was found out that old or Spoiled Milk can be combined with white vinegar, baking soda and water to produce strong and natural glue. The consumers acceptability survey conducted consumers perceived the natural glue produced from old or spoiled milk and other raw materials to have an excellent appearance. Viscosity and Adhesive strength and very good smell while the commercial glue was perceived to be excellent accures all the characteristics being surveyed. Furthermore, the commercial glue has higher weights means across all the four characteristics as needed when compared to the produced natural glue. However, the likes scale shows that there qualitative description were more or less the same, except for smell. This is an indication of consumers high degree of acceptance of the glue produced when marketed or sold.

Comparing the cost of production of the natural glue and the selling price of its commercial counterparts, it shows that php 37.80 was the cost of production of 600 mL natural glue from old and Spoiled milk, which accounts for php6. 30 per 100 mL, While 100 mL commercial glue costs php 30.00. This implies that the produced glue is p23. 70 or 79% cheaper than the commercial glue.

Based on the results and findings of the study, the following conclusions were drawn: Old or Spoiled milk can be ulitized as raw materials in the Production of Natural Glue,the natural glue from old or Spoiled milk has a high degree of Acceptability as compared to its commercial counterpart in terms of appearance, viscosity, smell, and adhesive strength, the natural old glue is cheaper by P23. 70 or 79% for every 100 mL volume as compared to commercial glue, and the hypothesis tested on appearance and adhesive strength was accepted. While, the hypotheses tested on viscosity and smell were rejected.
