The TRL system is a constant feed gasification system. It processes all raw materials, without regard to the type in a controlled manner; it gasifies all the organics and all inorganics are sterilized.

The heart of the system is a horizontally fed fluidized bed gasifier. The end products are electricity and biochar. Biochar is a carbon rich natural material which can be held in the soil for long periods of time with its high NPK values and which enables the soil to give stable harvests. Apart from this, the system does not produce any ash or waste.

There is no need for prior sorting out of the waste; however if it makes economical sense this could be done. Due to its modular design, its installation is very easy and fast; new modules can be added with simplicity to enlarge the capacity.

The system is equipped with a web based remote control system which enables the control from afar. With the PLC controls within the system, most of the automation can be accessed without experiencing any problems; working parameters can be adapted to different levels, thus creating a problem-free control mechanism.

Another advantage of the system compared with its competitors is the flexibility it offers to the different quality and variability of fuel. In this context, it can work with fuels that have as low calorific value as 2200 Kcal/kg and with fuels that has 60% humidity. The feeding of the gasifier is through conveyors that carries fuel in 15 cm dimension and through ash retrieval system.

Technical Specifications of the System:

• Waste processing capacity: 1 ton/day – 75 ton/day
• Energy consumption: 100 kWh to 1000 kWh (whole system)
• Installation area: 100 m² to 2000 m²

In the gasification plant established in 2007 in West Virginia/USA, broiler chicken waste is being gasified, producing renewable energy (heat) and biochar; biochar is being used for potato and corn growing and the heat is being used to heat the chicken barns.

The same system operates in 5 different locations in America, treating different waste and producing different products. However as the renewable electricity tariffs are very low/non-existent at those states where the system operates, electricity generation is not preferred. Only in Sanford/Florida, renewable electricity is produced from sewage sludge.

Minnesota/USA: capacity: 17 tons/day; raw material turkey manure

West Virginia/USA: capacity 17 tons/day; raw material chicken waste

Illionis/USA: capacity 34 tons/day; raw material cow manure, metal waste, all organic waste

The new version which works with the auger system processes cow manure and produces renewable energy (heat) and biochar. The resultant product is then applied mostly to the cow farm to be used for cow bedding.

The system in operation in Sanford/Florida can produce electricity from sewage sludge despite being the previous version of the technology.
