The Yard Hostel, Bangkok, Thailand

Yes, some of the structures are made form recycled shipping containers. And yes, recycled paper is used as insulation to keep the buildings cool. Inverter air conditioners and LED lights save energy and refillable glass water bottles for guests eliminate the need for plastic, while composted waste keeps the garden green – and the mojitos minty. But what is really remarkable about The Yard (a reference to both the greenery and a play on the Thai word for “relatives”) is its location at the heart of the galleries, boutiques and eateries of the cool Ari neighbourhood, a welcome respite from the concrete jungle and roar of traffic in the heart of Bangkok.

Baby Elephant Boutique Hotel, Siem Reap, Cambodia

The Baby Elephant is a sustainable-focused property in the heart of Siem Reap, where most visitors who come to explore the sprawling ruins of Angkor Wat stay. Waste becomes compost and food for farm animals, and cardboard and glass are reused on site or given to people who reuse the items, such as glass bottles that go to the roadside petrol vendors. Cooking oil is converted to biodiesel by the NGO Naga Earth. The on-site organic garden provides ingredients for the bar, kitchen, spa and for staff meals. It is also a Refill not Landfill drinking-water refill station. Baby Elephant has taken its approach to the environment seriously, working with experts to examine every aspect of its activity, from optimising water drainage to planning maintenance schedules, from reducing plastic to training staff to be environmentally aware. Even mosquitoes are kept under control with non-toxic, fan-powered traps and lemongrass in the garden.

Eden Eco Village, Kampot, Cambodia

Started six years ago on the banks of the Prek Teuk Chhou, a short ride outside Kampot, the Eden Eco Village is a collection of bamboo and thatch bungalows on stilts, many of them right over water – and each unit generates its own solar power for lights and fans. Most of the produce is local and the site grows its own mangoes. It recycles and composts everything it can, including the waste of the compost toilets for fertiliser. Life here is set to the rhythm of the water: riverside yoga in the morning, followed by kayaking or dips in the river, natural treatments in the women-only spa and the spectacle of fireflies at night. It’s a short trip to the plantations that produce highly-prized Kampot pepper, the colonial-era town of Kampot and seaside resort of Kep.

Lodges Ekologika, Pesawahan, Cicurug, Indonesia

Jakarta is infamous for its heavy traffic, so the contrast upon arriving at Lodges Ekologika couldn’t be more striking. Two hours ride from town (beat the gridlock by checking the train schedules), its bungalows are made of recycled teak, while salvaged leuit (traditional Sundanese rice barns) have been converted into shared accommodations. Rooms make use of solar power, collected rainwater and reused greywater, while 95% of staff can walk to work, and organic produce from the property’s own farm is transformed into some of the most lip-smacking food in the region. Lodges Ekologika has also started a reforestation programme that has reached 1,500 trees, and counting. There is also a campsite.

Janur Bungalow, Borobudur, Magelang, Indonesia

In the rolling hills above majestic Borobudur (the world’s largest Buddhist structure) and an easy drive from the historic towns of Jogjakarta and Solo, Janur’s bungalows are made from repurposed scrap wood, including beams and planks recovered from a demolished 100-year old rosewood house. One bungalow is actually an entire house saved and moved to the site. The handwoven roofs are made of local, sustainable bamboo, a distinctive feature of Javanese houses, known as limasan. The outdoor bathrooms allow guests to perform ablutions at one with their surroundings. Body scrub is made from a traditional recipe of ground spices, food is served on banana leaves and papaya stems are used as straws. The swimming pool is chemical-free, using reverse osmosis to filter the water instead.

On the island of Langkawi – popular for its beaches and lush landscapes – this resort takes the environment seriously: exhaustive lists explain the sustainable practices carried out by staff, most of which are invisible to guests. Much of the produce – including fish and fowl – are grown on site, and everything that can be is recycled, up-cycled or composted. With more than a decade of experience Frangipani preaches what it practises through conferences and forums around the region. Trainees are taken on in horticulture and environmental science and guests who want to learn about their work and the local eco-system can join an Eco-Walk.

Oasia Downtown, Singapore

The greenery that surrounds you when entering Oasia Downtown – on the facades, on the roof and throughout the public spaces – is eye-catching, but the stunning design is no empty statement about going green. The plants actually absorb solar heat, reducing the temperature on the facade by as much as 25C, resulting in more comfortable interiors and less energy spent on cooling the air. All public spaces in the hotel were designed to take advantage of cross ventilation and all aspects of the building – its orientation, the use of light and shade and the openness of the space – were designed to minimise energy use and maximise comfort. The irrigation system and air-cooling units use NEWater, Singapore’s high-grade reclaimed waste water that is part of the country’s plan to reduce its dependence on imported water.
