This study proposes two new mathematical models. These models aim to determine optimal ratio of using package for minimum waste in the environment. The models determine package usage ratios which minimize the packaging wastes when packaging amount is at maximum level in the environment. Models are distinguished from each other ignoring or not ignoring decay of each package in nature themselves. Proposed theoretical mathematical models have real world applications based on genuine data. These models easily can used by any enterprise which is concerned with environment and struggles to minimize the packaging waste.
