If the enzyme is transformed and changed from its original nature, it turns into a new and totally different substance. Thus, there is no problem in using it as a component of the fertilizers.
Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: According to the principles of fiqh, there is nothing wrong in Islam in using such fertilizers so long as this enzyme is merely one of the components of the entire system. Once it has been turned into compost, it can be used as a fertilizer to grow vegetables and crops. There is nothing wrong with this. For in this case, there is a process of total transformation of the original ingredient into something altogether different; so it is not different from alcohol turned into vinegar; for although alcohol is haram, vinegar is not.

However, if the by-products of the pig constitute the main components of the whole process, then we are best advised to use it for purposes other than growing food.
Finally, Muslims must embrace the concept of composting as a top priority. Since composting is the better environmentally friendly way of disposing our garbage, it is in perfect harmony with our Islamic mandate of taking good care of the planet earth.
