Wet Waste (Food & Kitchen/Vegetable waste) Dewatering Process

To tackle the pressing issue of high moisture content in organic waste, we've created an innovative solution specifically designed for large-scale waste generators in India.

Envicare has launched its “Dewatering Composter” product to address this issue and provide economical and sustainable solutions to organic waste management. This solution is based on three-step continuous processes (1) Primary Shredding (2) Dewatering & (3) Mixing

Shredding According to the basics of aerobic composting and science particle size of raw material should be as minimal as possible to make the process easy and fast.

  • We have designed and developed different types of shredding machines as per the client’s raw material requirements to achieve particle size below 10 mm
  • Stainless steel makes blades and valves used for a shredder to make it anti-corrosive and durable with a long life.
  • Continues process helps to process maximum material in a very short time.

Dewatering-: A screw press dewatering system is an excellent solution for controlling moisture levels in organic waste while preserving the nutritional value of the raw material. Here's why :

  • Gentle processing : Screw press systems use a gentle compression action, which helps prevent damage to the organic matter and preserves its nutritional content.
  • Effective moisture removal :The screw press design enables efficient removal of excess moisture, reducing the risk of anaerobic conditions and associated problems.
  • Adjustable moisture control :By adjusting the screw press's pressure and speed, you can precisely control the final moisture level, ensuring it's optimal for further processing or use.
  • Minimal nutrient loss :The screw press process minimizes the loss of nutrients, as it doesn't involve high-heat treatment, chemical additions, or excessive mechanical stress.
  • Versatility : Screw press dewatering systems can handle a wide range of organic materials, from food waste to agricultural residues.

By implementing a screw press dewatering system, you can effectively manage moisture levels while maintaining the nutritional value of the raw material, making it an ideal solution for organic waste management

Organic Waste Management Process

Step 1 : Segregation

Segregate organic waste from other waste streams.

Step 2 : (Dewatering Composter) Processing

  • Feed organic waste into the OWC
  • Shredding reduces the waste size to ≤10 mm.
  • Screw press dewatering reduces moisture levels.
  • Mixing generates aerobic digestion, producing pre-compost material.
  • Achieve 40-50% volume reduction.

Step 3 : Mixing Cycle

Run the mixing cycle for 15-20 minutes.

Step 4 : Curing System

Transfer the raw material to the curing system for:

  • Maturing process
  • Further biodegradation

Step 5 : Mature Compost

After 12-15 days in the curing system, mature compost is ready for use.
