Whenever possible we source supplies and products within 50 miles.
We understand the carbon footprint associated with transporting goods long distances and choose to source our produce locally.
Sourcing local food also ensures freshness and when it is fresher it has more nutrients.


Organic labels and systems are in the early stages in Thailand — and face challenges related to regulation and enforcement. In light of this, we work with suppliers we personally know and have built a relationship of trust and give preference to internationally certified organic products, i.e. USDA.

How do our purveyors conduct business? We expect our suppliers to be responsible in their operations and community. Working with businesses that share our same values is integral to our operation.


Relations between employers and employees are covered by the Thai Labor Protection Act (LPA). While the LPA helps ensure fair treatment, we are committed to gender equality and creating a healthy work environment.  Thailand rates 69 on the Gender Inequality Index (GII). 


We have a dedicated waste segregation area allowing for on-property sorting for recycling plastics, cans, paper, cardboard, tins, glass and a composting system for food waste to go back into the garden soil. We provide our guests with a convenient water refill station to help eliminate single-use plastic bottles.

Our EM (Effective Microorganism) Cleaning Products

We are in transition to use EM products for the following items: 
Bathroom cleaner, shower gel, shampoo and conditioner, hand wash, dish washer and water treatment.


Sanitizing guest rooms between stays and providing a clean hotel are a top priority, however, in doing so the use of toxic chemicals is not necessary. Instead, we use chemical-free Effective Microorganisms also known as EM (see image). This is a probiotic product which eliminates germs and odors, providing you with a comfortable visit without the harmful VOCs associated with toxic chemicals. 

The manufacturer of our EM cleaning products is Green Doilor, a local company. We are proud to share a safe way to clean and sanitize without the use of toxic chemicals. For more information about cleaning chemical-free with EM, click here ›

In addition, the environmentally-friendly room toilet cleaner and oil degreaser by  InnuScience have replaced our regular cleaning agents and we are still in the process of upgrading our range of in-house cleaning products to minimize the use chemicals. 

In an effort to provide the best air quality possible, Green Tiger House does not use harmful, chemical-laden, air fresheners. Instead, our cleaning staff is meticulous when cleaning, which eliminates potential sources of odor. The result, no need to “cover up” bad odors, and no need to use toxic chemicals used in traditional air fresheners.
