With Cleantech Discussion board Asia 2025 simply across the nook, it’s an opportune time to revisit a few of the insights shared eventually 12 months’s occasion in Singapore.
The town-state is Southeast Asia’s agri-food tech hub; with that in thoughts, we hosted two periods at Cleantech Discussion board Asia 2024 centered on sustainability innovation within the agriculture and meals worth chain.
In right now’s weblog publish we’ll revisit the primary of these periods, which checked out novel approaches to valorizing waste and different aspect streams from agri-food manufacturing.
About 6% of worldwide emissions are particularly linked to loss and waste in agri-food techniques; double the emissions popping out of the aviation sector. When that waste results in landfills it decomposes and generates methane and might trigger toxicity in soil and water via leaching.
And these are simply the ecological impacts of meals loss and waste. In a world with a rising inhabitants and a shrinking quantity of obtainable land to develop crops, decreasing wastage is extra pressing than ever to strengthen world meals safety.
Novel Feedstocks
Favor is one firm that’s aiming to unravel this drawback, whereas additionally tackling the carefully interrelated problems with threat and carbon depth in one of the vital fragile agricultural provide chains there may be: espresso.
The Singapore-based start-up is upcycling agri-food byproducts like soy pulp from tofu and soymilk manufacturing, spent grain from beer brewing, and surplus bread from bakeries. It ferments these feedstocks to emphasise taste compounds much like these present in bean-derived espresso. The ultimate product is a floor espresso different that Favor sells to foodservice institutions, in addition to ready espresso merchandise that it distributes itself.
Talking at Cleantech Discussion board Asia 2024, Favor co-founder and CTO DJ Tan defined that espresso is often extra emissions-intensive, when it comes to carbon dioxide emitted per kilogram of produce, than dairy merchandise, hen, fish, or pork.
“Agriculture can also be undermining itself, as local weather change reduces espresso yields,” he mentioned. “Our course of emits considerably much less carbon. By our estimates, we’re about 10 occasions extra sustainable than conventional espresso.”
Becoming a member of Tan on the panel was Kai-Ning Chua, co-founder and CMO at Insectta. Beginning out as a black soldier fly farm in 2018, the Singaporean firm later pivoted away from farming operations to focus on extraction and manufacturing applied sciences that may maximize the worth of the waste being recycled by the bugs.
“Whereas most individuals affiliate insect farming with animal feed or fertilizer, we give attention to prescribed drugs, cosmetics, and natural electronics,” Chua advised attendees.
At present, Insectta companions with farm operators to extract two high-value compounds from the black soldier fly: chitosan, which can also be sourced from crustaceans, and is utilized in numerous industries from healthcare and packaging to agriculture and water therapy; and melanin, which has purposes in electronics and regenerative drugs.
“Our insect-sourced model has no heavy metals and better purity [and] we will produce it at a a lot decrease price and make it water soluble, which is an trade first,” Chua mentioned.
Funding in Meals Waste Innovation
Nevertheless, regardless of the obvious promise of those improvements, meals waste upcycling start-ups like Insectta and Favor proceed to face challenges in relation to convincing would-be buyers.
Some nonetheless “assume we’re an insect farm,” mentioned Chua. “Many buyers know that insect farming is a low-margin, scale-driven enterprise. We have to make clear that we’re in biomaterials, not farming. As soon as we do, we clarify that we add financial worth by producing high-purity, useful components that assist sustainable manufacturing.”
For Tan, too, making the financial case as clear as potential is what will get buyers over the road.
“As soon as they see we’re addressing an actual ache level – rising espresso costs and provide chain points – they get it. Our answer is market-driven,” he mentioned.
That method helped the corporate shut a $2M Seed spherical only a few months earlier than Cleantech Discussion board Asia 2024, with participation from buyers together with 500 International, Higher Chew Ventures, Sopoong, Seeds Capital, and Entrepreneur First, amongst others.
It’s Not Simply Traders That Want Convincing
Improvements like these developed at Favor find yourself in merchandise that buyers drink or eat; and within the case of Insectta, merchandise that buyers could also be making use of to their pores and skin, or utilizing to deal with wounds.
“We attempt to downplay the bugs,” Chua mentioned. “The thought of utilizing bugs in our drugs or cosmetics; there may be an emotional barrier there. So, in relation to our messaging, it’s very clear: We make chitosan and melanin for these industries that’s extra useful, that has extra financial viability, and sustainability is definitely within the background.”
Favor’s technique has been to intentionally keep away from mentions of ‘waste’ in its client branding and advertising efforts, based on Tan.
“What we now have discovered is that individuals are extra prepared to just accept one thing as soon as they’ve first tried it. They fight [Prefer] and say, ‘Hey, this does style like my common cup of Joe’. After which we inform them, ‘By the way in which, no espresso beans have been utilized in that’. After which we see their minds shatter in entrance of us.”
