The Source Bulk Foods already has plans for its flagship outlet at Great World City by the end of this year, followed by a third outlet in the Central Business District early next year.
Mr Rob Behennah, 52, The Source Bulk Foods' British master franchiser for South-east Asia, notes that the plastic-free lifestyle has taken root in Singapore.
The Singapore permanent resident says: "People are becoming more aware, environmentally conscious and recognising the importance of sustainable living. Increasingly, there is information being shared and consumers are becoming less daunted by the idea of aspiring towards a zero-waste lifestyle.
"If there is a nationwide initiative to minimise the availability of single-use plastics, such as through restricting the use of plastic bags, straws and cutlery, we know it will lead consumers and retailers alike to further adopt zero-waste shopping."
Local players are not surprised that these big names are here and hope this will create more awareness among consumers.
Mr Allann Tay, 38, co-founder of Reprovisions, says: "Big bulk food brands opening in Singapore is quite a natural occurrence in the retail scene. They definitely help to pique people's interest."
But he is also wary of brands expanding too quickly.
He says: "The rate at which people are mentally ready to embrace such lifestyle changes needs to be in tandem with the rate of such openings for businesses to be sustainable. More innovation is required as many, if not most, items in the supermarkets still use plastic packaging or plastic as a core material."
And while the concept is gaining traction in the heartland, Mr Tay still faces challenges.
He says: "We get questions such as 'Why do I need to buy in this unpackaged manner?' and 'Is it cheaper than in supermarkets?' Some people shop in a more budget-conscious manner as opposed to being concerned about the state of the world."
Aside from educating consumers, businesses are also constantly sourcing new products.
For example, Ms Florence Tay, 37, founder of social enterprise UnPackt, recently launched reusable facial cotton pads to reduce the use of single-use ones.
She says: "To start an eco-friendly journey doesn't cost an arm or a leg - it can be as simple as saying no to a single-use disposable you don't need or reducing your carbon footprint by supporting local makers. It also sends the message to businesses that local consumers are prepared to go plastic-free."
Ms Tricia Leong, 35, who works in the real estate sector, says: "My friends and I already have our own metal drinking straws and cutlery, along with reusable shopping bags and cups.
"The next step for us is to buy our groceries at bulk food stores like Scoop Wholefoods. I like that I will no longer have a bag of rice or flour sitting in the kitchen when I would usually require only a small portion for just me and my husband."
