Composting

WTT specializes in composting of organic waste. Composting is an efficient process to turn organics into a valuable fertilizer or refuse derived fuel.

The WTT In-vessel composting technology is an advanced and robust system that ensures maximum process efficiency and minimal emissions.

Why Compost?

Less 
Garbage

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Reduce
 Gases

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Recover Valuable 
Materials

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Decrease 
Erosion

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Reduce the
 Need to Water

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Reduce 
Pesticides

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Save 
Money

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Healthy 
Gardens

Organics represent over one-third of materials being sent to landfills, and over 50% of total waste.

Composting Made Easy

WTT’s biological tunnel process is individually controlled in order to provide each batch with a tailor-made treatment. WTT’s fully automated process allows the operator to set process parameters to adapt different waste categories and seasonal influences.

Its modular construction and versatile control software interface allows the same facility to treat organic waste optimally in short a period of time, maximizing processing efficiency and keeping environmental conditions strictly under control.

Key Features

In-Vessel Composting

The WTT-staff were involved in the first biowaste-tunnel-composting-installation in 1994 and have subsequently built over 1300 tunnels. Throughout this time WTT has continuously improved the design and identified methods of reducing the capital and operating costs.

frame controlling all parameters

The WTT fans ensure optimal operation at minimal energy usage

Maturation Processes

After the first high intensity composting in the tunnels optionally maturation bays or aerated windrows can be added to achieve the required maturity. These system can also be applied as a primary process for leave and yard waste.

Feed
Your Soil

After the composting process the compost is refined to your specs by mechanical treatment to make the final product.

Compost is the single most important ingredient for a healthy and productive soil:

  1. It provides essential organic matter to the
soil for health and vitality
  2. Compost aids nutrient retention, reducing fertilizer cost
  3. It helps to enhance soil structure and
decrease erosion
  4. Water retention is improved, giving better drought resilience
  5. Compost naturally suppresses plant diseases
