How to Make Eco Enzyme at Home

Eco enzyme is a complex solution produced by fermentation of raw kitchen waste (fruit and vegetable scraps), sugar (preferably brown sugar, jaggery or molasses sugar) and water.

It is dark brown with a vinegary smell. Eco enzyme can be used for multiple purposes, including household cleaning, dish wash, hand wash, fertilizer, sanitizer, etc. Eco enzyme is environmentally friendly as it reduces CO2, purifies the atmosphere and can be easily made at home.

Ingredients and equipment

Vegetable and fruit scraps (raw)

Sugar (brown sugar, jaggery or molasses sugar)


Airtight plastic container (plastic containers are preferable to avoid possible explosion of the container as gasses build up.)


Measure water, fruit/vegetable scraps and brown sugar with a ratio of 10:3:1 respectively (e.g. 10 kgs water, 3 kgs fruit/vegetable scraps, 1 kg brown sugar).

Chop the fruit/vegetable scraps into small pieces (this is optional to speed the process).

Mix all ingredients into the plastic container and stir. The mixture should only take up eight tenths of the container (i.e, not full) to allow for a smooth fermentation.

Close the container, making sure it is airtight.

Leave it for 3 months in a sheltered place.

After 3 months, a successful eco enzyme will turn dark brown and smell vinegary.

Remove the organic waste residues from the enzyme by filtering it and keep it in small containers for later use.

Note: During the first 10 days of fermentation, loosen the lid of the container one or two times a day to release the trapped gasses. Push the floating dregs downward once in a while.

After 10 days, the lids only need to be loosened every few days, repeate until the end of the third week. It may have white, black or brown layer on top of the eco enzyme, that is just fine.

Such a layer is a good sign of the fermentation process. So, please don’t remove it.

Also, it is normal that there might be some worms or insects in the mixture.

If the liquid turns black with a bad smell, add the same amount of sugar used at the beginning and stir the mixture well, close the lid tight. After one month, the mixture will be fermented.

Notes: You can accumulate fruit and vegetable scraps gradually in the mixture made from the same ratio of 10:3:1 as mentioned in Step 1 above. The 3-month fermentation process starts from the last day of your adding in fruit/vegetable scraps.

Expiry date: There is no expiry date for the eco enzyme. Occasionally open the lid to release air. DO NOT STORE IN THE REFRIGERATOR.

Enzyme usages

There are various enzyme usages, based on which weaker or stronger enzymes can be made. Below are the dilution ratios for different enzyme usages used at Inner Space Centers for your reference.

  • For purifying vegetables: Ratio (1:100); i.e. 1 enzyme : 100 water (for example: mix 50ml enzyme into 5 litres of water). Vegetables and fruits can be soaked in the diluted enzyme for 15 – 30 minutes to purify them.

  • For household cleaning: Ratio of about (1:100); i.e. 1 enzyme: 100 water (for cleaning floors).

  • For reducing the amount of chemicals in shampoo, dish washing liquid, washing powder, etc: Ratio (1: 1: 10); i.e. 1 enzyme: 1 dish washing liquid / shampoo / washing powder: 10 water. Finally, wash and rinse 2-3 times with clean water as usual.

  • For cleaning toilet: Pour 250 ml of enzyme into the toilet and flush it. This will help prevent clogging and clear the pipes.

  • For spraying flowers and plants to reduce insects: Ratio (1: 500-1000); i.e. 10ml of enzyme mixed with 5-10 litters of water).

  • The organic waste residue can be used for the following usages:

  • For enriching the soil and fertilizing plants: The organic waste residue can be used as fertilizers for up to 3 months to improve the hardened soil and it is suggested to leave the soil to rest during this time. Or it can be apply around plants keeping it 15 – 20 cm away from the stem.

  • For preventing clogging at toilet or sewage.

The above content is composed based on the links below and our practical experience. This is just basic information that we would like to share with you. You can have more information from the internet regarding different ways of making eco enzyme. One of our volunteers for example makes eco enzyme without using sugar.

We hope you enjoy making ECO ENZYME, save money, be healthier, while helping the environtment. We look forward to hearing and learning from your ideas and experiences.
