General objectives of the pre-treatmentREDWAVE WASTE

Loosen up the incoming waste as a pre-condition for an optimal air flow in the biodrying process

Shred the waste to a uniform particle size to ensure a consistant material flow in the downstream process

Open up bags if recyclables shall be recovered

Recover plastics, paper and other recycables

Homogenise the incoming waste

Open up composite materials

Objectives of the Biological dryingREDWAVE WASTE

Dry the waste with heat generated by the degradation of the organic matter

Loss of moisture > 25%w/w per week

Centralised leachate collection

Variable control systems allow the use of the drying unit for different applications

CompostingDrying

Biofilter• Depending on the application the intelligent control

system can be set up to regulate the air flow for the best degradation or drying process.

Objectives of the refining processREDWAVE WASTE

Sort out inert materials (aggregates, glass, etc.)

Shred the SRF to meet the required particle size

Recover ferrous and non-ferrous

Recover PVC to reduce the chlorine content of the SRF

Fuel (SRF)

Advantages of the bio-drying process

REDWAVE WASTE

Unlike thermal drying no fossil fuel or external heat is required (low power consumption)

High percentage of landfill diversion achievable (up to 85% recovery - SRF, metals, recyclables, inert’s)

Only inerts go to landfill and can be used as landfill cover

Low space requirements due to short retention time of the waste inside the biodrying unit (7-10 days)

Outgoing products meet industrial requirements (SRF, metals, recyclables)

SRF is recognized as a quality fuel for thermal recovery (Power plants / cement kilns / etc.)

Proven and reliable technology with 15 years of operational experience all across Europe

Typical composition of dried SRFREDWAVE WASTE

Renewable energy sources (cardboard/paper, textiles, wood, organics, fine

fraction) approx. 65% by weight

Foreign / inert mate-rials

(stone, glass, metal) <1% by weight

other fossil fuels (textiles, rubber, com-

pounds, etc.) approx. 25% by weight

Plastics Approx. 9% by weight

Calorific value: 14 – 18 MJ/kg

Moisture content: <20% w/w

Percentage of MSW: up to 50% w/w

When should Bio-Drying be favoured?

REDWAVE WASTE

If there is a need for high quality SRF (i.e. cement plants etc.) on the market

If you have min. 30.000 tpa of waste (3 drying units)

If landfill space is short or if landfilling of untreated waste will be banned shortly

If landfill tax increases year by year

If the wet waste is not suitable for an efficient incineration (i.e. high temperature)

Higher separation efficiency achievable after drying

High degree of process automation…

REDWAVE WASTE

Fully automated loading & unloading processoperated by cranes

Efficient air circulation system leads to small a amount of exhaust air

Fast biological drying process (6 days) . Reduction of the moisture content

from 40% down to < 20%

High degree of sorting efficiency & safe working places!

REDWAVE WASTE

Due to the dried waste excellent separation results are obtained

Fully enclosed and ventilated equipment

Clean and safe working places

Proven & reliable sorting process with plantavailability > 90%

High degree of sorting efficiency & safe working places!
