You can use 5% of the remaining pulp known as pulpy vinegar obtained from the first batch as a starter for the next batch of bio enzymes. This way, the time the next batch will take to get ready will be half, i.e. 45 days. The number of gases released now will be generated for 15 days instead of 30 days, and the container can be kept in an airtight position for 30 days instead of 60 days. You can prepare bio-enzymes at home.
