According to the, a Wuxi city local news media, Mr. Hu, the person-in-charge of the factory, assured that the foul smell is harmless.

In January 2015, DLH received order from a U.S. customer, supplying up to 5 metric tons of algae powder as raw ingredient for making bioplastics.

Since last year, DLH has been conducting research on processing the harvested algae into raw meterial which can be further processed into bioplastic ingredients.

In July 13, 2015, featured a news about the economic value of blooming algae harvested from lake Taihu of China. The dried algae powder were  sold to the USA at the price of USD 500.00/ton. An USA company discovered the method to convert the dried algae into valuable bioplastic ingredient.

Algix LLC, a company based in Georgia, is the only company in USA that converts bloom algae biomass into biodegradable plastic and 3D-printing materials.


On 24 August, 2015, Algix LLC and Effekt LLC announced the creation of the worlds first algae-derived flexible foams. Both companies joined forces in a joint venture entitled Bloom Holdings LLC to commercialize the foam.

According to, the foam is produced in a patented process that utilizes Algix’s dried algae biomass (GMO-free) which is solely collected from waste streams across the US and Asia.

The local environmental protection agency and the city government had issued a cease work order for “conducting unauthorized algae experiments” and summoned an administrative penalty to the company for “operating an algae processing factory without a licence”.

DHL company’s staff, Mr. Tao, explained in a local news media that “We have done nothing wrong. We are not conducting experiments. We are doing business and we have invested money on our business.”

Mr. Hu, the person-in-charge of the factory, had no idea when they could resume their company’s operation. The company signed a sales contract with their USA customer to deliver 1,400 metric tons of algae powder in batches through the end of next year.
