Recycling and
Waste Disposal
At RENATUS, we recycle and dispose of waste and scrap generated through our customers’ business activities.
We react swiftly to changes in laws, regulations, and social trends, cater to the varying needs of our customers, and use optimal methods to carry out the recycling, resource recovery, and final disposal of waste in a responsible manner.
Incineration and melting
We treat industrial waste, specially controlled industrial waste —including infectious waste— and municipal waste from business activities using a combination of incineration, melting, and recycling processes.
In our efforts to recycle as much waste as possible, we convert the burnt ash, particulate matter, and slag generated via incineration and melting processes into raw materials and fuel for the civil engineering and cement industries.
We also effectively utilize the waste heat emitted via incineration processes to generate electricity via thermal recycling.

Mixing and adjusting, neutralizing,
and oil separation
We recycle the waste oil, liquid, and sludge, as well as the contaminated soil generated from production and other activities at factory sites, using methods that have been optimized for the waste’s properties.
Our oil separators convert waste oil into high-quality recycled fuel equivalent to fuel oil. We treat waste liquid and sludge through a combination of mixing and adjusting, neutralization, reforming and sorting, and purifying processes, and recycle it into auxiliary fuel for incinerators, or into raw materials and fuel for cement.
