Reclaiming the Future: Sustainable Innovations in Material Use

In Lagos, an oak door salvaged from a demolished government building becomes minimalist benches at Nsibidi Studio. "We’ve been working like this since we opened in 2017," says Emem Effiong, founder of the studio. "The point isn’t to recycle. It’s to show that materials with history can be part of a modern aesthetic." Effiong’s team collaborates with demolition companies across Nigeria to source wood, aluminum, and structural steel that would otherwise be discarded.

Effiong is among many designers globally rethinking material use to address environmental pressures. The city produces approximately 13,000 metric tonnes of solid waste daily, according to a 2022 report by the Lagos State Waste Management Authority. Designers like Effiong view this as an opportunity. “Lagos is a goldmine of unused materials,” she notes, outlining plans to formalize partnerships with construction firms.

This approach is mirrored worldwide. In Copenhagen, the Danish architecture firm Lendager Group specializes in incorporating upcycled materials into large-scale projects. Their Resource Rows development, completed in 2019, utilized concrete panels from demolished buildings to create new façades. "It’s not upcycling for the sake of a trend," said CEO Anders Lendager during a panel discussion at the 2023 Venice Architecture Biennale. "It’s about closing material loops at an industrial scale."

Upcycling isn’t the only pathway toward sustainability. High-performance buildings designed to consume minimal energy while ensuring user comfort represent another frontier. The Eastgate Centre in Harare, Zimbabwe, designed by architect Mick Pearce with Arup engineers, exemplifies this. Completed in 1996, the building employs a biomimetic approach inspired by termite mounds to regulate internal temperatures without traditional air conditioning. This innovation saves approximately 90% of the energy required to cool conventionally designed buildings of similar size, according to a 2020 retrospective published in Engineering Sustainability.

New tools are enabling architects to push the boundaries of material and energy efficiency. Parametric design software allows for precise modeling of complex geometries, reducing material waste. At the 2023 Lagos Design Week, architect Ngozi Okeke presented a prototype pavilion made from parametrically cut bamboo, a rapidly regrowing material that sequesters carbon. "This is both a digital and a natural solution," Okeke explained. "It’s sustainable in its materials and methods."

Critics of sustainable design often cite higher upfront costs. Reclaimed materials require additional processing and testing to meet safety standards. However, advocates argue that long-term savings from lower energy use and extended material lifespans outweigh these initial investments. Okeke emphasizes, "Sustainability isn’t cheap, but neither is climate inaction."

Institutions are starting to agree. In 2023, the Aga Khan Award for Architecture recognized projects prioritizing sustainability, including the Barjeel Art Foundation’s new headquarters in Sharjah, UAE, which uses locally sourced, low-carbon materials and photovoltaic panels. Jury member Marina Tabassum, a Bangladeshi architect, highlighted the building’s "deep respect for both environment and context."

Effiong believes public policy can accelerate sustainable practices. She cites the success of South Africa's Green Building Council, which incentivizes eco-friendly developments through certification programs. "Imagine if we had something like that here in Nigeria," she muses. Effiong’s studio recently participated in a workshop organized by the African Design Centre in Kigali, Rwanda, on scaling sustainable practices across the continent.

The economic potential of sustainable design is gaining visibility. A 2022 report from the Ellen MacArthur Foundation estimated that transitioning to a circular economy in construction could unlock $1.2 trillion annually in savings worldwide by 2030. Designers caution against overemphasizing economic metrics. "This isn’t just about money," says Lendager. "It’s about survival."

Despite optimism, barriers remain. Access to reclaimed materials is uneven, and certification processes can be complex. Sustainable design still occupies a niche within the broader architecture and construction industries. "We’re not mainstream yet," admits Okeke. "But bit by bit, we’re getting there."

The next challenge may be cultural. "Sustainability has to feel aspirational," argues Effiong. She points to global brands like Patagonia, which frame environmental responsibility as integral to their identity. "When people see sustainable design as beautiful, as something worth aspiring to, that’s when we’ll see a real shift."

For now, studios like hers continue to innovate. Their work raises a question: What would a city built entirely from reclaimed, low-carbon materials look like? In Lagos, the answer feels like a possibility waiting to be carved from salvaged wood.
