By incorporating Gicom composting technology with Brentwood’s solid waste size reduction, screening and materials handling manufacturing capabilities, Brentwood are able to realise projects including design, manufacture, construction, commissioning and training on a turn-key basis.

Since 1984 GICOM, a Dutch based company, has designed and realised computer controlled growing cells' and 'tunnel composting facilities' for both the mushroom growing and waste processing industries.

Tunnel composting facilities are used to:

• Compost different organic waste streams (biowaste, MSW,
  sewerage sludge, industrial sludge, manure, digested
  residue, etc.) into high quality compost;
• Produce different types of mushroom compost: phase 1,2 and 3;

The above mentioned 'GICOM products' are built upon 3 different technology fields:

• Measurement and control devices
• Biotechnological process control
• Air handling systems

The necessary soft and hardware systems have been developed and produced within the GICOM organisation. Brentwood / GICOM are able to realise projects on a turn-key basis, providing professional design and planning services and incorporating construction and management teams during construction on site.

As an innovative company GICOM owns and operate several pilot plants to maintain its position as provider of state of the art tunnel composting technology. Current and future customers can use the GICOM after sales service: a 24-hours-a-day service department able to answer questions and to solve problems.

GICOM composting systems is a company operating all over the world - from Europe to Australia and from America to Asia!
