In 1858 Heyman established himself as a commodity broker of grain, butter and other food products. In 1861, he was granted citizenship as a merchant. He was one of the merchants, who made Denmark's foreign trade independent of Hamburg in the years after 1864. When a regular service with steam liners was introduced between Copenhagen and England and Scotland in 1863, he began an export of Danish quality butter in original packaging to the United Kingdom. In 1864, he was the first in Denmark to establish a production of canned quality butter for sale to overseas markets. In 1866, with H. Puggaard & Co. as a silent partner, he established an abattoir, Kjøbenhavns Svineslagteri, specializing in the slaughtering of pigs for the British market. It was located at Strandboulevarden 134 in Østerbro and was inaugurated just one year after the first facility of its kind in Copenhagen had opened at Bodenhoffs Plads. In 1873, together with C. F. Tietgen, and Rudolph Puggaard, he went on to found Tuborgs Fabrikker in Hellerup on the coast north of Copenhagen. The activities included Tuborg Brewery, a fertilizer and sulfuric acid plant, and a glassworks. Heyman left the board in 1875 due to disagreements regarding its management, but took over as managing director and chairman in 1880. In the 1880s, Heyman expanded his pork meat business through the opening or acquisition of a number of new abattoirs. Two of these, one in Varde and one in Assens, were opened in 1883. In 1880, with local partners, he established the Engelska Svineslagteriet in Malmö, later followed by a smaller branch under the same name in Tomelilla. He also acquired the abattoir in Maribo as well as significant stakes in the abattoirs in Aalborg and Hjørring, Vejle and Skælskør. In 1890–91, together with British partners, he established an abattoir in Waterford, Iceland, but pulled out when it did not perform as expected. Starting in the late 1890s, Heyman worked for the merger of all Danish abattoirs, both privately owned and co-operatives, into a single company, "A/S De danske Svineslagterier", and after a few years he was joined by C. F. Tietgen who had already instigated similar mergers within a number of other industries, but the co-operatives ended up creating their own company under the name Slagteriselskabet Danmark.
