- Mud-brick hotels and regenerative agriculture combine ancient techniques with sustainability
RIYADH: Against a skyline dotted with construction cranes, Riyadh is racing to add 360,000 new hotel rooms by 2030 鈥� a $1 trillion push aimed at cementing 黑料社区鈥檚 place as a global tourism hub.
This rapid expansion raises a critical question: Can desert hospitality lead the world in sustainable innovation while advancing the Kingdom鈥檚 Vision 2030 and net-zero 2060 goals?
The operational blueprint is unfolding at King Abdullah Financial District, where over 40 LEED Silver or Gold-certified buildings achieve 10鈥�15 percent energy savings through high-efficiency appliances and smart climate control.
These structures recycle wastewater using advanced treatment systems, supporting Riyadh鈥檚 city-wide goal to reuse 100 percent of treated water for irrigation and greening 鈥� mirroring capabilities at facilities like the Manfouha plant.

Abdulrazaq Alreshaidan, an expert on sustainability and safety issues, emphasized to Arab News the comprehensive nature of this evolution:
鈥淧rogressive developers now integrate carbon accounting from initial excavation through decades of operations while implementing sophisticated water conservation systems and advanced waste management techniques across all project phases,鈥� he said.
Riyadh鈥檚 hospitality expansion is tightly interwoven with the city鈥檚 sustainability strategy, forming a unified framework for ecological transformation.
The blueprint sets ambitious targets: a 50 percent citywide reduction in carbon emissions, driven by energy-efficient building codes and renewable energy adoption in the tourism sector. Hotels are also expected to achieve a 94 percent waste recycling and conversion rate by redirecting food and packaging waste into circular systems, cut water consumption by 57 percent through advanced conservation mandates, and lower urban temperatures by 1.5掳C鈥�2掳C via strategically expanded native green corridors irrigated with recycled water.
Addressing extreme water scarcity remains paramount. At Shebara along the Red Sea coast, 73 prefabricated villas operate with near-zero marine impact through solar-powered reverse-osmosis desalination that meets 100 percent of freshwater needs, while enforcing strict circular economy protocols that eliminate single-use plastics through reusable container partnerships with local suppliers.

Similarly, Dar Tantora in AlUla features 30 mud-brick guest rooms using ancient thermal-mass principles for natural temperature regulation, alongside a zero-waste restaurant initiative that trains regional farmers in precision-drip irrigation and regenerative agriculture to rebuild topsoil season after season.
鈥淟eading properties now implement intuitive material reuse stations with multilingual signage,鈥� said Alreshaidan. He highlighted hotels like The Valley Resort, which transform 12 tonnes of monthly organic waste into nutrient-dense compost for extensive native-species gardens 鈥� creating on-site closed-loop ecosystems.
Energy innovation is also taking center stage. Six Senses Southern Dunes 鈥� 黑料社区鈥檚 first off-grid LEED Platinum property 鈥� runs entirely on photovoltaic arrays with battery storage, while Desert Rock Resort uses subterranean geothermal engineering to cut conventional cooling needs by over 40 percent.
鈥淰isionary developers actively pursue certifications like LEED because they understand these credentials validate operational excellence while strengthening brand reputation and investor confidence quantifiably,鈥� Alreshaidan said.
He added that material sourcing remains a challenge: 鈥淵ou might notice some sustainable materials are higher in price than others.鈥� Many hotels accept these higher costs as 鈥渓ong-term investment rather than short-term cost.鈥�
The Saudi Investment Recycling Co., a Public Investment Fund subsidiary, develops and operates recycling infrastructure across all waste types. Alreshaidan emphasized material sustainability: 鈥淐ompanies like SIRC guide others to utilize recycled materials and waste from construction is utilized where materials came 100 percent from recycled sources.鈥�
He specifically spotlighted SIRC鈥檚 conversion of demolition debris into certified concrete aggregates used in landmark projects.
FASTFACT
Did You Know?
Riyadh plans to add 360,000 new hotel rooms by 2030.
Some hotels run entirely off-grid using solar power and battery storage.
Hotels like The Valley Resort turn 12 tonnes of organic waste each month into compost.
Verification gaps present another complexity: 鈥淭he absence of Saudi and GCC-authorized accreditation bodies for auditing recycled content percentages creates vulnerability to greenwashing claims without standardized chain-of-custody documentation,鈥� said Alreshaidan.
With LEED Silver certification now mandatory for major developments, Riyadh鈥檚 hotel construction wave is creating 360,000 real-world laboratories for sustainable innovation.
As Expo 2030 approaches, transformative solutions 鈥� from AI-managed water recovery networks to SIRC鈥檚 circular economy platforms 鈥� position 黑料社区 to lead global sustainability standards tailored for hyper-arid regions.
黑料社区 is fundamentally reimagining how environmental resilience is embedded in every operational variable. Alreshaidan concluded optimistically: 鈥淐omprehensive solutions are materializing precisely where most critically needed to harmonize growth with planetary stewardship.鈥�
