IN Brief:
- Niedergebra in Germany will gain close to 9,000 tonnes of annual recycled mixed polyolefin capacity.
- Wildon in Austria will add up to 5,000 tonnes of recycled polyethylene capacity, including material for flexible packaging.
- The German capacity is due in early 2027, with the Austrian expansion scheduled later that year.
Borouge International is expanding mechanical recycling capacity at Niedergebra in Germany and Wildon in Austria, adding close to 9,000 tonnes of annual recycled mixed polyolefin output and up to 5,000 tonnes of recycled polyethylene capacity.
The German project is due to enter operation in the first quarter of 2027, while the Austrian expansion is scheduled for the fourth quarter. Niedergebra processes mixed post consumer polyolefin waste for rigid applications, whereas Wildon is focused on recycled polyethylene, including grades intended for flexible packaging. The distinction is important because those end uses demand different material characteristics even when both originate from recycled plastic.
Mechanical recycling retains the polymer structure rather than breaking plastic back into chemical feedstocks, so the quality of the finished recyclate depends heavily on the incoming waste stream. Material must be collected, sorted and prepared before usable fractions are reduced in size, washed where necessary, melted, filtered and converted into a product that can return to manufacturing.
Mixed polyolefin waste can contain several grades of polyethylene and polypropylene alongside labels, closures, residues and other contamination. Sorting removes incompatible material, but the remaining blend still varies in melt behaviour and mechanical properties. A rigid moulded component can tolerate a different level of variation from a thin film, where small inconsistencies become more visible as the material is stretched and processed at speed.
This makes the Wildon expansion particularly relevant to flexible packaging. Film production depends on predictable melt flow, tensile behaviour, thickness control and sealing performance, while contamination or inconsistent polymer properties can create gels, weak spots or processing instability across a comparatively thin structure. Recycled polyethylene therefore has to perform consistently enough that converters do not spend the environmental benefit through lower line speeds, higher scrap or repeated process adjustment.
Niedergebra faces a related but different requirement because its additional output is aimed at mixed polyolefins used in rigid applications. Sorting efficiency and feedstock consistency still determine the usable output, but the acceptable property window can differ from film production. Borouge’s strategy of expanding separate routes for different polymer streams reflects that technical distinction rather than treating recycled polyolefin as one interchangeable material.
The group already operates a site at Elin Pelin in Bulgaria producing more than 20,000 tonnes a year of recycled polypropylene grades, giving it a European network spanning polypropylene, polyethylene and mixed polyolefin feedstocks. Once the German and Austrian projects are commissioned, nominal capacity will rise by roughly 14,000 tonnes a year across the two expansions.
That additional capacity arrives as packaging manufacturers face increasing pressure to raise recycled content while preserving pack performance. The EU Packaging and Packaging Waste Regulation is already influencing material development, but regulatory targets do not make recycled resin automatically suitable for every production line or food application.
Converters still need material that melts, flows and cools inside a predictable operating window. If recyclate varies too widely between deliveries, line temperatures, speeds or blending ratios may need repeated adjustment, increasing downtime and scrap. Feedstock quality therefore matters alongside installed recycling capacity because an extrusion line can only produce specification material from the fractions available to it.
Food packaging introduces a further constraint because not every post consumer stream is suitable for direct food contact. Material may instead be used in non contact components, incorporated behind a functional barrier or directed towards applications where regulatory requirements differ. The usable market for the new capacity will consequently depend on the individual recycled grades and the structures into which they are converted.
Flexible packs add several manufacturing stages after resin production, including film extrusion, printing, lamination, slitting, forming and sealing. Each step can amplify defects introduced earlier, so the commercial value of Wildon’s additional polyethylene will depend on how consistently those grades survive complete converting processes rather than simply meeting a resin specification at the factory gate.
The same principle applies to the overall capacity figure. Roughly 14,000 extra tonnes expands the amount of plastic that can potentially return to manufacturing, but saleable output will ultimately be set by collection quality, sorting efficiency, commissioning performance and customer specifications. Borouge is adding the physical capacity; the industrial test will be whether enough suitable waste can be converted into recyclate that packaging manufacturers can use repeatedly without compromising productivity or pack performance.
