Chilli is one of India's most chemical-intensive crops, yet the smallholders who grow it have long carried the cost: payment that took up to three months, opaque markets, and exposure to banned pesticides. Plant Lipids' NURTURE 360 Chilli Programme, launched in 2021, starts from a simple idea: farmers will only farm sustainably if it pays. Village procurement centres bring the market within 3 km of the farm, weighing is done in the open, and payment arrives within 72 hours. Premiums reward integrated pest management and a phased move to regenerative farming, while unmarked jute bags keep illegal dyes out of the food chain. The results are measurable. Over four seasons, the programme has paid US$ 53.5 million directly to farming families, and two government laboratories have recorded a 22% rise in soil organic carbon. When sustainable farming pays, farmers do not need to be persuaded.

In the Kerinci highlands of Jambi, cinnamon takes at least eight years to reach harvest. Jutarasa plants patchouli as living ground cover beneath the young trees. It controls weeds without chemicals, holds soil on steep slopes and is harvested three to four times a year. The still is fired with cinnamon trunk left after bark harvest, instead of firewood from the forest edge. Synthetic pesticides and fertilisers are banned in every partnership agreement.

Naatu Sampangi, India's native single-petal tuberose, was being lost to hybrids. Synthite's SENS programme brought it back. A dedicated nursery returned native bulbs to farmers, and 92 acres now grow the native cultivar around Tiruvannamalai, Tamil Nadu. The model is direct and transparent: village procurement centres replace middlemen, and 187 smallholder farmers are paid electronically every seven days, around 20% above production cost and benchmarked to a living income. More than a third of the farms are women-led. Cultivated with 30% fewer inputs and a lower carbon footprint, the crop carries independent UEBT verification. Human rights due diligence is delivered through an intensive engagement programme with the Fair Labor Association, alongside leading agricultural research institutes for crop technology and production. Proven on a single flower, the model is now scaling and replicating across other crops and geographies.

Vinasamex turned a fragmented cinnamon supply chain in Văn Bàn District, Lào Cai, into a certified, traceable organic system. It works with ethnic minority smallholders from Tày, H’Mông and Dao communities. Farmers are trained in organic cultivation and sell directly to Vinasamex at stable prices. Fourteen farmer groups manage the certified area. Women are about 80% of participants and hold about 70% of leadership roles. Partners include the Lào Cai Agricultural Extension Centre and SNV.

In Guadix, Southern Spain, where water is scarce and agriculture has shaped the landscape for generations, the Zalabí Model applies organic and regenerative farming, precision irrigation, renewable energy and circular distillation to crops including Red Thyme, Rosemary, Spanish Marjoram and Spanish Sage. Designed with the long term in mind, the model delivers lower resource use, yields above conventional benchmarks and a low product carbon footprint, while creating skilled rural jobs and keeping more value where the essential oils are produced.

Berje has sourced South African buchu since the 1970s. With partner Waterfall Health Farms, it helped move supply from mostly wild harvesting to cultivation. This protects wild plants in the Cape Floristic Region. Through the Buchu Association, it supported an industry-wide Access and Benefit Sharing agreement, signed in 2023. The agreement is with the National Khoi and San Council and the South African San Council. Benefits include payments and skills training, such as the Buchu Short Course.

Absolutes have long been extracted with petrochemical solvents such as hexane. Through continued research and investment in green chemistry, LMR advanced natural extraction with renewable extraction solvents: this includes an organic plant-based solvent, and a CO₂ process using upcycled, natural and renewable CO₂, expanding its portfolio of conscious ingredients with no petrochemical residues. This innovation enabled the first COSMOS-approved absolutes while preserving the olfactive richness of natural ingredients. It is also rooted in long-term sourcing partnerships, allowing more sustainable cultivation practices and fair income opportunities for farming communities. One example is the Fair For Life-certified jasmine supply chain in southern India.

Most of the world’s vanillin is made from petroleum. Borregaard’s EuroVanillin Supreme is made from Norway spruce, from PEFC-certified forests. It is produced in an integrated biorefinery in Norway, which turns the whole tree into useful products. Compared with guaiacol-based vanillin, it emits about 90% less CO₂. It gives flavour and fragrance companies a renewable, drop-in alternative with a stable supply.

Indesso’s programme covers both its factories and its patchouli sourcing areas. Wastewater recycling and rainwater harvesting cut water intensity by almost 30% across three manufacturing sites. Treatment sludge is turned into compost instead of waste. In Southeast Sulawesi, Indesso helped about 300 patchouli farmers build rainwater ponds. These store water through long dry seasons, protecting crops and farm incomes.

At Waslee Downs in Western Australia, Main Camp WA grows approximately 250 hectares of Eucalyptus polybractea for essential oil production. Six centre pivots and metered bores enable efficient, precision irrigation in a high-evaporation climate, while onsite wind energy powers the operation. Spent eucalyptus biomass is returned to the land, supporting soil health and nutrient cycling. Livestock from neighbouring farms also graze within the plantation, helping manage vegetation while creating shared value with the local farming community.

Many aroma ingredients rely on fossil feedstocks or palm and coconut oils. ChainCraft ferments low-value food industry residues into high-purity fatty acids. These renewable building blocks, such as bio-based caproic acid and n-hexanol, are drop-ins for existing flavour and fragrance applications. Their first full-scale plant in Groningen, the Netherlands, will be co-sited with Royal Avebe’s potato starch processing plant. It will turn 300,000 tonnes of potato juice into clean water and 20,000 tonnes of renewable fatty acids each year.

Avilan sources tonka beans in the Bolívar-Amazonas region of southern Venezuela. About 50 collection points serve local and Indigenous communities. Only fallen fruit is collected, so the trees stay standing. Buying directly from harvesters has raised their income about 12-fold since 2020. The tonka season lasts four months, so Avilan now also buys angostura bark to cover more of the year. The aim is to keep harvesters out of illegal gold mining. The tonka operation is FairWild certified.
