You have a poultry farm and a poultry-processing unit. Which product can you make using the waste products from your processing unit?

The product that can be made is pet food.

From the waste products of the poultry processing unit there can be made pet food, mostly for cats and dogs. Most of the waste products would be highly nutritional for the cats and dogs, as it will be parts of meat, organs, and bones, and both of those pets are carnivores, thus need those things in their diet.

The waste products can be all mixed and processed together, or make multiple different products from them each, depending on the demand on the market.
