Fly ash
Fly Ash refers to the airborne ashes and dusts that are produced as a result of combustion of solids. Depending on the composition of the burnt material, the Fly Ash may contain hazardous waste. The Fly Ash from Industrial and Municipal waste incinerators typically contains hazardous heavy metals. Recupyl has developed a patented process for the neutralisation of fly ash and valorisation of the heavy metals contained in the ash. Recupyl's process requires lower treatment temperatures that the competing plasma torch technique.

Pickling bath
Pickling baths are no longer effective once the concentration of metal exceeds a certain level.
Recupyl has developed a patented process to recycle the acidic or alkaline solution as well as extracting the valuable metal content.

Steel dust
Electric Arc Furnaces (such as used to produce recycled steel) produce significant volumes of iron-rich dust as deposits in the furnace filter systems. Recupyl, through its Recupac subsidiary, has developed a range of patented processes to recycle the Steel Dust into valuable compounds such as Iron Oxide based pigments

Metallic dust

Nitrates reduction
Recupyl has developed a process to reduce the content of Nitrates in effluent waste.

Cathode Ray Tube (CRT)
Until recently, Televisions and Computer displays used cathode ray tubes as the active component. Whilst all new displays are now based on flat screen technologies, there remain a large volume of CRTs in active use. Thus used CRTs remain a significant waste stream to be recycled. Recupyl has developed a technique for the efficient separation the component glasses and extraction of the luminous powders.

Asbestos is a fibrous material that was used in the past as a heat resistant insulation material. Fibres of asbestos are hazardous as they lead to fibrosis if inhaled. Recupyl has developed a process to fuse asbestos fibres into harmless glasses suitable for building composites.

WEEE - Waste Electrical and Electronic Equipment
Waste Electrical and Electronic Equipment (WEEE) forms an increasingly significant proportion of industrial and municipal waste. WEEE contains a complex mixture of plastics, metals (some heavt metals and some precious metals) and other materials. The European WEEE directive obliges member countries to put in place collection and treatment schemes for WEEE. Recupyl's processes are able to recycle an increasing proportion of WEEE wastes including batteries, CRTs and flat screens.

Process for recycling
Recycling of most materials is carried out by following a series of steps in a Recycling Process. Recupyl's recycling processes typical comprise a mechanical stage to separate the components of the waste, followed by targeted hydrochemistry to extract valuable metals.
