TL;DR

A 1946 Swedish military report investigates a mysterious yellowish, porous, and explosive material found in Njurunda. The investigation concludes the material is not a standard product of local industry, though it shares characteristics with explosive byproducts of rubber manufacturing.

On August 5, 1946, Eric Malmberg of Fli 3 filed a report regarding an investigation into a mysterious substance discovered in Njurunda, Sweden. The primary objective of the visit to various Sundsvall industrial sites was to determine if the yellowish, porous material found at the site was a byproduct of local manufacturing. Malmberg visited the Swedish Cellulose A.B. research laboratory in Skönsmon, the Svartvik sulfite factory, and the Stockviksverken facility. After consulting with research manager Dr. Tydén and chief engineers Eidem, Flodén, and Fürst, Malmberg concluded that the substance did not originate from these facilities, nor from any other factory within the Cellulose group. However, Chief Engineer Fürst noted that the material, particularly its odor, resembled 'cauliflower formations' that occur during the production of Neprén rubber at Stockviksverken—a substance noted to be explosive. Malmberg also attempted to contact a pilot named Lindén, who had witnessed the impact and collected the material, but was unable to reach him on August 3rd or 4th.

Det har dock en viss likhet, i synnerhet betr lukten, (enl överingenjör Fürst) med s k "blomkålsbildningar" som uppstå vid framställningen av Neprén-gummi vid Stockviksverken. Detta ämne är explosivt.

Official Assessment

The substance does not originate from the visited factories or any other factory in the Cellulosa group. It bears a resemblance, particularly in smell, to 'cauliflower formations' produced during the manufacture of Neprén rubber at Stockviksverken.

The material found at Njurunda is not a product of the local Sundsvall industries, though it shares chemical similarities with explosive byproducts of Neprén rubber manufacturing.
