Germany’s Construction Aluminium Demand Falls 12%: 2027 Recovery & Recycling Unlock Growth Prospects
Meta Description: Germany’s construction-related aluminium consumption dropped 12% between 2022 and 2025 amid a prolonged industry downturn. A 2027 construction recovery, infrastructure investment and expanding closed-loop recycling are set to create fresh sector growth opportunities.
Germany’s construction industry has endured years of contraction, weighed down by elevated financing costs, high building material prices and subdued residential investment. The downturn has pulled construction-related aluminium consumption down by around 12% between 2022 and 2025, but the market outlook is starting to shift. A projected 2027 recovery in construction activity, paired with infrastructure investment and growing closed-loop aluminium recycling, is opening new growth avenues for domestic suppliers.
Prolonged Construction Downturn Weighs on Demand
The construction slowdown began in early 2022, initially driven by surging energy and raw material costs. Mortgage rates above 4% have further suppressed residential construction, dragging down activity across residential, non-residential and civil engineering segments. After partial rebounds in 2024, the overall industry contracted a further 3% year-on-year in 2025.
Recent activity indicators point to continued softness. The S&P Global Construction PMI Total Activity Index dropped to 43.5 points in September 2026, from 48.7 in August, with new orders still declining albeit at the slowest pace in three months.
The German Construction Industry Federation has revised its 2026 growth forecast down to 1% from an earlier 2.5%, citing weak activity and rising costs. Residential construction growth expectations were slashed to just 0.5%.
Construction Aluminium Consumption Tracks Sector Weakness
Construction accounts for 15–16% of Germany’s total aluminium usage, spanning extrusions, sheets, profiles, windows, doors, facades and architectural systems, making it a core end-use segment for the domestic aluminium industry.
Total German aluminium consumption fell from 3.33 million tonnes in 2022 to 2.93 million tonnes in 2025. Construction-related aluminium use dropped from 499,500 tonnes to 439,500 tonnes over the same period, a 12% decline that broadly aligns with the 10% drop in overall construction activity.
Notably, the two do not always move in lockstep. In 2024, for example, construction activity rebounded but aluminium consumption remained sluggish, as shifts in project composition, material selection and renovation activity altered demand intensity independently of overall output.
2027 Recovery: Infrastructure & Non-Residential Projects Lead
While 2026 growth is set to be modest at 1%, the medium-term outlook is more positive. Construction industry growth is projected to reach roughly 2% in 2027, and average 3.5% annually between 2027 and 2030.
Residential construction, which makes up 60% of the total, remains the biggest drag. However, forward-looking indicators are stabilising: price-adjusted orders are set to rise 10% from 2026, residential construction loan volumes are up 21%, and building permits increased 10.8% last year. New residential investment is projected to grow 2% in 2026, supported by government subsidies.
Non-residential and infrastructure investment will be the stronger growth engine. Data centre construction orders rose 5% in 2025 and are set to keep climbing. Transport infrastructure, renewable energy projects and power grid expansion will also drive demand for aluminium components, conductors, mounting systems and façade elements.
Closed-Loop Recycling Adds a Second Growth Avenue
Alongside recovering construction demand, Germany is making steady progress in building closed-loop aluminium recycling within the building sector.
Industry body AUF collected 75,000 tonnes of aluminium scrap from buildings in 2023 through its national network of 300 collection points, equal to roughly 58% of the estimated 130,000 tonnes of building-sector aluminium scrap generated that year. Most recovered material is remelted and reused in new building products, forming a largely closed value loop.
Expanding recycling reduces reliance on primary aluminium, improves access to secondary raw materials and supports production of lower-carbon building components. Further improvements in material identification, selective demolition and alloy-specific sorting could raise both the volume and quality of recovered scrap, strengthening the circular value proposition for construction aluminium.
Outlook: Gradual Recovery Ahead
Weak residential activity, high financing costs and uncertain investment conditions remain material headwinds in the near term. The projected 2% construction growth in 2027 will not translate directly to an equivalent rise in aluminium consumption, as demand will depend heavily on project mix and material intensity.
Still, the trajectory is improving. Stabilising residential indicators, growing infrastructure and data centre investment, and a maturing closed-loop recycling system together create a credible pathway to renewed growth for Germany’s construction aluminium sector, supporting a more efficient, resilient domestic value chain.
