About a study on the influence of electricity on mental capabilities, Frederick II was reported to have said: If he is able to provide reason for the half wits in my Prussian states using electricity, then he is worth more than his own weight in gold.

In 1776 Achard was elected to the Royal Academy of Sciences at Berlin

Achard revived the discovery by Marggraf in 1747 that sugar beets contained sugar, and devised a process to produce sugar from sugar beets. Beginning in 1789, he planted various sugar-bearing plants on his manor in Kaulsdorf near Berlin. Because of their efficiency, he soon preferred sugar beets. In the following year he studied different varieties of beets and the influence of fertilisers. The research was interrupted when Kaulsdorf manor burnt down and had to be sold. Achard later continued on the manor Französisch Buchholz

 and Moritz, Freiherr von Koppy. In 1806 Achard's plant was burned down by Napoleon's war and in 1910 it was rebuilt on a small scale. Embargoes by Napoleon kept cane sugar imports away from Germany and thus the growing and refining of sugar beets became highly important for the Prussian government.

. France itself built many refineries and was only in later years surpassed by Prussia.

English sugar merchants offered Achard 200,000 taler to declare his experiments a failure but he refused. With Achards discovery, sugar was no longer a luxury product, but became a necessity, due to the embargoes. Achard taught classes to have a large number of sugar beet growers and the specially developed sugar beets became available for everyone. The culture of the sugar bowl began.

In 1794, Achard built an optical telegraph between Spandau

Due to Archard's financial difficulties as a result of several fires in 1806, his refineries were declared bankrupt in 1815. He died, destitute, in 1821 in Wohlau. His life's work was carried on mainly by French industrialists such as at the refineries of Matthias Christian Rabbethge
