Borouge International is expanding mechanical recycling capacity at plants in Germany and Austria, adding almost 9,000 tonnes of annual recycled mixed polyolefin output at Niedergebra and up to 5,000 tonnes of recycled polyethylene production at Wildon.
Niedergebra is expected to add its new capacity during the first quarter of 2027, increasing production of recycled mixed polyolefins for rigid applications at the former mtm plastics site. Wildon, the former Ecoplast operation in Austria, is scheduled to follow during the fourth quarter of 2027 with additional recycled polyethylene aimed particularly at flexible packaging.
Those investments broaden a European recycling network that already includes Borouge’s Elin Pelin facility in Bulgaria, which produces more than 20,000 tonnes a year of recycled polypropylene grades. The three sites cover different polymer streams and downstream requirements, giving the company separate production routes for mixed polyolefins, recycled polyethylene and recycled polypropylene.
Mechanical recycling preserves the polymer chain rather than returning plastic to basic chemical feedstocks, leaving the processor to manage much of the variability already present in collected waste. Material has to be sorted, washed, dried, filtered and remelted before pellet production, while contamination, incompatible polymers and degradation from previous processing cycles affect the properties of the recovered resin.
Mixed polyolefin streams are especially demanding because polyethylene and polypropylene occur in many products and grades with different melt behaviour and mechanical characteristics. Sorting removes obvious incompatible material, but the feedstock entering the plant remains more variable than virgin resin produced to a controlled reactor specification. Processing therefore has to accommodate that variation while keeping finished pellets within a specification customers can use reliably.
Niedergebra and Wildon are being developed for different downstream requirements. Rigid products depend on properties including stiffness, impact resistance and dimensional stability, while flexible film exposes small gels, particles and inconsistencies that may be less significant in a thicker moulded component. Wildon’s focus on polyethylene for flexible applications consequently puts particular emphasis on melt consistency, filtration and contamination control.
Installed capacity provides only part of the usable output because each tonne of incoming waste contains material that may be unsuitable for the target grade. Labels, dirt, moisture, incompatible polymers and other residues have to be removed, with the resulting yield determining how much saleable resin remains after sorting and processing.
Feedstock availability can restrict output before the extrusion line reaches its nominal capacity. Recyclers need a reliable flow of post consumer material within the polymer mix and cleanliness range their equipment can process, making collection and sorting infrastructure part of the same supply chain as the recycling plant. Additional machinery cannot deliver its rated output if unsuitable material is rejected before or during processing.
Borouge is expanding while European packaging producers face higher requirements around recycled content and recyclability under the EU Packaging and Packaging Waste Regulation. Those requirements increase demand for recycled polymers that can enter established manufacturing processes without causing unacceptable changes in cycle time, film quality, mechanical performance or appearance.
Material specification therefore remains closely tied to the intended application. Melt flow, colour, odour, residual contamination and strength all influence processing behaviour, so separating production between rigid applications, flexible polyethylene and polypropylene gives Borouge greater control over the grades offered to customers.
The German and Austrian investments also increase regional supply at a time when manufacturers are placing more emphasis on resilience. Borouge supplies recycled material from other markets, including polyethylene film grades through its Syndigo operation in Indiana and externally sourced material in Asia, while additional European production can reduce reliance on longer international supply chains for customers seeking regional material.
Niedergebra is expected to provide the first additional tonnes in early 2027, followed by Wildon later in the year. Output from both sites will depend on maintaining feedstock quality, process yield and batch consistency as throughput increases, particularly where recycled material enters rigid products or thin films with demanding processing tolerances.
Almost 14,000 tonnes of additional nominal capacity will therefore be realised through the interaction between collection, sorting, extrusion and quality control rather than equipment capacity alone. Stable output requires variable post consumer waste to be converted into resin that behaves predictably enough for manufacturers to raise recycled content without destabilising their own production lines.
