We produce high-quality aspartame since 1991

About us

About us

HSWT is the new name for a well-known company in the sweetener industry. HSWT is owner and operator of the production plant based in Gravelines, France. The plant has produced and sold high-quality aspartame to global customers since 1991.

The plant

The plant was built in 1991 through a joint-venture of the US-based NutraSweet and the Japanese-based Ajinomoto, both active in sweeteners and other food ingredients. From 2000 to 2015, Ajinomoto had full ownership over the plant. In 2015, the plant was acquired by HYET Sweet, a Dutch-based company trading in sweeteners.

In January 2019, the plant was taken over by Standard Investment, a European investment firm specialized in manufacturing and food companies. The French plant makes the same products as before at the same high-quality levels just under a new legal name and new ownership.


HSWT produces food-grade aspartame for well-known brands of soft drinks, juices, chewing gums and tabletop sweeteners. In addition, HSWT produces pharma-grade aspartame that is used by well-known pharmaceutical companies in their product formulations.

While in the past the plant has produced other sweeteners, HSWT today has a pure focus on the manufacturing high-quality aspartame for the food and pharmaceutical industries.

Aspartame is produced from combining amino acids which are commonly present in natural food proteins. Aspartame is digested by the human body in the same way that proteins are and the sweetener is approved by more than 120 countries, including the EU and USA.
