How to Use Pig Manure to Make Pellet Fertilizer?

Pig manure, a byproduct of pig farming, is a valuable organic resource that can be transformed into nutrient-rich pellet fertilizer for your plants and garden. Recycling pig manure not only helps reduce waste but also provides a sustainable solution for improving soil fertility and promoting healthy plant growth. In this guide, we will explore the process of converting pig manure into pellet fertilizer and outline the steps for effectively using it in your garden.

I. Collecting and Preparing Pig Manure:

  1. Gather fresh pig manure: Collect fresh pig manure from a reliable source. It’s essential to choose manure from healthy pigs that are not treated with antibiotics or other medications, as these substances can be detrimental to plants and soil organisms.
  2. Composting the manure: Transfer the pig manure to a compost bin or pile. To accelerate the composting process and reduce odors, consider mixing the manure with carbon-rich materials like straw, sawdust, or dried leaves. Aim for a balanced ratio of approximately 3 parts carbon to 1 part manure.
  3. Turn and monitor the compost: Regularly turn the compost pile to provide aeration and ensure proper decomposition. Monitor the moisture level, keeping it slightly damp but not overly wet. Within several weeks to months, depending on various factors such as temperature and composting conditions, the pig manure will transform into nutrient-rich compost.

II. Pelletizing Pig Manure:

  1. Gather the necessary materials:
    • Composted pig manure
    • Organic binder (optional)
    • Pelletizer machine or pelletizing kit
    • Protective gear (gloves, goggles)
  2. Prepare the composted manure: Once the pig manure has fully decomposed into compost, ensure it has a crumbly texture. If the compost appears too dry or lacks cohesion, you may choose to add an organic binder like vegetable oil or water to improve pellet formation. Mix the binder thoroughly into the compost.
  3. Use a pelletizer machine or kit: If available, utilize a pelletizer machine or pelletizing kit specifically designed for organic materials. Follow the manufacturer’s instructions for setup and operation. Feed the composted manure into the machine, and it will compress and shape the material into pellets of uniform size.
  4. Hand-rolling pellets (alternative method): If a pelletizer machine is not accessible, you can form the pellets by hand. Take small amounts of composted manure and roll them between your hands to create compact pellets. Aim for a diameter of around 1-2 centimeters (0.4-0.8 inches) for ease of use.

III. Using Pig Manure Pellet Fertilizer:

  1. Allow the pellets to dry: Whether formed by a machine or hand-rolled, the pig manure pellets need to dry before application. Spread them out on a clean surface or drying rack in a well-ventilated area. Let them air dry for several days until they become firm and hard.
  2. Applying the pellets to the soil: Dig small holes or trenches near the base of your plants or garden beds and place a few pig manure pellets in each hole. Cover the pellets with soil and water the area lightly to aid in their dissolution and nutrient release.
  3. Monitoring and reapplication: Observe the growth and health of your plants and monitor the nutrient requirements. Depending on the needs of your plants, reapply pig manure pellet fertilizer every few weeks or months. Adjust the frequency and quantity based on the plant’s growth stage and nutritional demands.

Conclusion: Transforming pig manure into pellet fertilizer offers a sustainable and organic solution for enhancing soil fertility and supporting healthy plant growth in your garden. By following the steps outlined in this guide, you can efficiently utilize pig manure as a valuable resource while reducing waste and promoting environmental stewardship. Happy gardening!

Best Way for Pig Farm Waste Management

Pig farm waste management is the processes and systems utilized to gather, treat, and dispose of waste generated by pig farms. That can also involve liquid waste (urine and wash water) and solid waste (manure and bedding). The goal of pig farm waste management is to lessen environmental odors and impacts while also recovering essential nutrients from the waste, which you can use as a fertilizer.

Some of the common methods utilized in pig farm waste management include:

  • Anaerobic digestion systems for breaking down organic matter and generating biogas
  • Aerobic fermentation composting systems for breaking down piggery waste
  • solids separation systems for separating the solid waste into a liquid fraction and a solids fraction

What Are the Most Common Methods for Managing Pig Farm Waste?

You will find various methods for dealing with the waste generated by pig farms. Some of these are the following:

Waste treatment and recovery

These are advanced treatment systems that can treat the piggery waste, recover the water and fertilizer, and treat the rest of the solid and gas for energy production.


With this method, pig waste is burned to lessen the amount of waste and to regulate the release of pollutants.

Anaerobic digestion

The procedure of anaerobic digestion includes gathering pig manure waste in airtight containers or vessels and enabling it to decompose through anaerobic bacteria. The resulting biogas could be utilized to produce heat or electricity.

Aerobic composting

But anaerobic digestion cannot kill harmful substances in swine farm waste. Aerobic composting is better. After separating the solid waste into a liquid fraction and a solids fraction, pig waste is mixed along with other organic materials like sawdust or straw and enabled to decompose through aerobic bacteria. The resulting compost could be utilized as a fertilizer without odor and scathe. Using SX composting machine, you even can compost swine waste within 20 days.
