Design + Build
Unique waste treatment solutions for all
Convertus offers turnkey design and build projects for mechanical and biological treatment facilities, with a focus on source-separated municipal organic waste.
We Think Ahead
Convertus is committed to delivering quality throughout our cycle of service. We specialize in solid project delivery, innovative solutions, and strive to understand and anticipate our customer’s key requirements.
Our system of delivery is built on years of operational experience and extensive knowledge. From process design and engineering to testing, installation, training and service, we’ve created a consistent feedback loop that ties our solutions together.
Smart Solutions in 3D
Each of our waste treatment facilities is meticulously designed. Drawing on our expertise and state-of-the-art technologies and engineering knowledge, the design of each facility is completed in a detailed 3D-drawing. Based on this 3D-model, our engineers create accurate and specific 2D-drawings which will be used for fabrication and assembly.
Our standard modular skids will be used where possible to make efficient delivery possible and reduce the installation time and errors.
Our Technologies
Convertus is the largest and most advanced organic waste processor in Canada. Every waste treatment project we work on is unique. We have the expertise to provide you as our client and partner with an array of waste treatment technology solutions to deliver the most optimal results, based on your specific needs.
We have spent years strengthening our technologies so that they are as efficient and customizable as possible. All of our installations include one, or a combination of the following technologies:
Heat Harvest
With the increased importance of renewable energy and rising interest in by-product heat utilization, we’ve developed and patented a technology called Heat Harvest. Heat Harvest repurposes the thermal energy generated from the composting process.
Composting & Biodrying
Our biological in-vessel composting (IVC) tunnels use forced aeration to process organic waste into compost. This fully automated process allows each facility to adapt to different waste streams and seasonal fluctuations.
Anaerobic Digestion and Biogas
Anaerobic Digestion (AD) is an ideal circular solution, creating biogas from organic waste streams. This biogas can be converted into renewable heat and power, or injected to the natural gas grid.

Odour Abatement
It is the nature of the waste we handle that some odour will occur. However, it should never negatively impact our neighbours. Our engineers can meet the most stringent odour abatement criteria and design each odour abatement system specifically to your requirements so that odour can be detected and managed in the right way.

Phase 1
Castaldo S.p.A. | 2016
The Giugliano project was separated into two separate phases. During Phase 1 in 2016 we designed and built the Giugliano facility to process 36,000 t/a of source separated organics, including approximately 80% household organics and 20% leaf and yard waste. The facility uses 13 dryAD tunnels and/or 10 composting tunnels to convert organic waste into compost and biogas. The biogas that is generated at the facility is collected, stored, treated and then converted into electricity and heat using a combined heat and power unit (CHP). The electricity is primarily used to power on-site equipment, while the remainder is transferred to the public grid. The thermal energy generated is used in the dryAD and conditioning systems. The Giugliano facility was among the first built in Naples (Campania) region where up to 700,000 tons of organic waste is generated each year.
KEY EQUIPMENT for Phase 1:
13 dryAD tunnels and 10 composting tunnels, including biogas treatment and storage.
Phase 2
In 2016, we were awarded the contract for the design and build of a second composting facility for Giugliano. The Giugliano Composting Facility treats approximately 65,000 t/a of organic waste, which includes a combination of food and leaf/yard waste. The incoming waste is first shredded and then spread across one of eight composting tunnels with a capacity of approximately 700m3 each. After the biological composting process — which takes approximately 14 days — the compost is removed from the tunnels and separated in a screening line to sort the material into three fractions:
1. Fine fraction (fresh compost ≤10mm), which undergoes maturation onto an aerated floor in one of the six maturation bays for a total of 28 days.
2. Intermediate fraction (material between 10-80 mm), which undergoes refining mainly to remove plastic films so that it can be recirculated in the biological process.
3. Oversize fraction (material >80mm) is removed from the process.
KEY EQUIPMENT Phase 2:
8 composting tunnels and 6 maturation bays including air treatment; 2 humidifiers and 2 biofilters.
Kompostwerke Rhein-Sieg GmbH & Co. KG | 2018
In 2018, together with Kompostwerke Rhein-Sieg GmbH & Co. KG (KRS) we built a state-of-the-art composting facility for municipal organic waste. We were responsible for the design and construction of all civil and process equipment works. The facility includes a large receiving area and logistical building with air curtains, ventilation systems, nine composting tunnels, a humidifier and three biofilters. All of this is connected using WTT communication equipment. The high-quality compost produced at this facility is screened on site and sold to local markets for agricultural applications. A three-year full maintenance contract is in place to guarantee operational excellence and customer satisfaction.
KEY EQUIPMENT:
9 composting tunnels, 3 biofilters and 1 air humidifier.
KAVG | 2019
In 2019, we began updating the existing household and commercial waste treatment lines for KAVG. The plant, which was built in 2005 and had been modified several times, required significant upgrades to meet the new commercial waste regulations. We were responsible for disassembling the old machinery and installing new equipment. To reach the requested recycling rates, we installed new vibrating screens, a wind sifter, an NIR sorter, a FE- and NF-sorter and all required steel structure and conveyors. We also tried to use as much of the existing materials as possible, to reduce the amount of scrap metal. Finally, the existing SCADA was also updated.
The project was completed in a period of three-and-a-half months, which enabled the client to start production and increase the sorting capacity and purities.
KEY EQUIPMENT:
2 x vibrating screens, magnet, Eddy current, 2 x wind sifter, 2 x NIR, baler, conveyor, steel structure.
