In September 1939, Dynamit - Aktien Gesellschaft Fabrik Bromberg was established on the outskirts of Bydgoszcz. Production included explosives: smokeless powder, nitrocellulose, nitroglycerin, TNT and dinitrobenzene. The plant was owned by the global company Dynamit - Aktien Gesellschaft vormals Alfred Nobel & Co.

In February in 1945, after World War II, the remaining infrastructure after Dynamit - Aktien Gesellschaft Fabrik Bromberg was adapted for the Polish manufacturing market. From then on, there was a Polish factory called the State Powder Plant in Łęgnowo.

On December 4, 1948, in the State Gunpowder Factory in Łęgnów, the first installation producing explosives for the mining industry and the army was launched. Explosives produced for military and civilian purposes include, for example, TNT, pentrite, tetryl. This event is treated as a symbolic beginning of the Polish Chemical Plant "ZACHEM" in Bydgoszcz.

The successor of the State Powder Works, operating from February to the end of December 1945, was the Nitrochemical Plant Łęgnowo, established on January 1, 1948. The production profile still included explosives for military and civilian purposes: TNT, pentrite and tetryl. Then the plant was transformed into a state-owned enterprise under the name of Wytwórnia Chemiczna No. 9 in Łęgnów, which was established by order of the Minister of Chemical Industry of July 30, 1951.

On November 19, 1952, Wytwórnia Chemiczna No. 9 in Bydgoszcz, which was producing TNT, was shaken by a powerful explosion that was heard within a radius of several kilometers. As a result of the catastrophe, 15 employees were killed, 84 were injured, 132 buildings were destroyed, and the factory left a crater with a diameter of 80 meters. Within a radius of about 10 km, windows were broken in hundreds of houses.

The years 1953-1960 saw the development of the production of "civilian" products, including processed polyvinyl chloride (PVC), dye intermediates, dyes, pigments, optical brighteners, phenol. In 1956, there were the following departments: dyes, plastics synthesis, organic intermediates, experimental and special (production of explosives). On January 1, 1959, the factory changed its name to Zakłady Chemiczne w Bydgoszczy.

Since 1963, the inhabitants of the villages of Plątnowo and Łęgnowo have noticed the deterioration of water quality in utility wells. Inspections and tests of water quality carried out by the Provincial Sanitary and Epidemiological Station in Bydgoszcz showed the appearance of phenol compounds in groundwater. Due to the location of these towns in the vicinity of the Chemical Plant, and also from the north-west, reaching the sewage canal of the aforementioned Plant, it was found that the only possible source of these compounds is the Chemical Plant in Bydgoszcz.

In 1971, the production of flexible polyurethane foams (PUR) and polyurethane foam shapes used for the production of, for example, car seats produced by the domestic automotive industry was launched. In October 1971, the name of the factory was changed again. From then on, it was Zakłady Chemiczne "ZACHEM" in Bydgoszcz.

In 1976, Zakłady Chemiczne "ZACHEM" in Bydgoszcz started the production of epichlorohydrin (EPI), rigid foams and moldings made of polyurethane foams for the automotive industry. Pursuant to the ordinance of the Minister of Chemical Industry of April 19, 1976 on changing the names of state-owned enterprises that are part of the Organic Industry Association Organika, the name of the Company was changed to "Zakłady Chemiczne Organika - Zachem".

The years 1981-1990 were characterized by the continuation of basic production and generally no significant development. At that time, projects of changes in basic processes, especially aniline, nitrobenzene and phenol, were prepared in order to reduce their adverse impact on the environment. Economic analyzes and the scale of the necessary outlays resulted in the abandonment of these projects as ineffective, and the Eco-restructuring of production program was developed.

In 1990, the Chemical Plant "Organika - Zachem" continues chemical production. In that year, a Report of the Provincial Center for Environmental Research and Control (WOBiKŚ) in Bydgoszcz was issued on the exceedance of emission standards of chemical compounds, including nitrobenzene, benzene, sulfur dioxide, chloropropane, hydrogen chloride, phenol, toluene, xylene, ethanol, sulfuric acid and freon.

On April 1, 1990, the production of phenol was discontinued at the Chemical Plants "Organika - Zachem", the installations particularly burdensome for the environment were closed: aniline, nitrobenzene and a number of organic intermediates, dyes and dye intermediates

In 1991, due to the plant's negative impact on the environment, in particular on underground waters, landfills at Zielona street of polluted groundwater, the so-called "barrier intake" at Plątnowska street. It consisted of three exploitation holes. The intake was put into operation in 1992.

On January 1, 1992, the state-owned enterprise under the name of Chemical Plants "Organika - Zachem" in Bydgoszcz was divided into Chemical Plants "Organika - Zachem" in Bydgoszcz and Chemical Plants "Nitro-Chem" in Bydgoszcz. This division involved the separation of civilian and special (military) productions.

On April 1, 2000, pursuant to the decision of the Minister of the State Treasury of January 31, 2000, the name of the company was changed again to Zakłady Chemiczne "ZACHEM". At the request of "ZACHEM", on August 18, 2000, the Kuyavian-Pomeranian Voivode appointed a negotiation commission to establish the "Adjustment program for "ZACHEM" in Bydgoszcz" which is part of the procedure of conditional deletion from the "List of 80" plants that are the most burdensome for the environment in the country.

By decision of January 4, 2001, the Chief Inspector of Environmental Protection conditionally deleted Zakłady Chemiczne "ZACHEM" in Bydgoszcz from the "List of 80" plants most harmful to the environment. In 2001, work began on a thorough modernization of the toluene diisocyanate (TDI) installation, which allowed for doubling the production capacity.

The first step towards the privatization of Chemical Plants in Bydgoszcz was the creation of a sole-shareholder company of the State Treasury. The enterprise was transformed into a joint-stock company with 100% share of the State Treasury represented by Nafta Polska. On May 5, 2003, the name of the factory was changed to Zakłady Chemiczne "ZACHEM" joint stock company in Bydgoszcz.

The main production of "ZACHEM" joint stock company in Bydgoszcz included toluene diisocyanate (TDI) used in polyurethane foam production plants and epichlorohydrin (EPI) used in the production of epoxy resins. In addition, the production profile included the processing of polyvinyl chloride (PVC) for the automotive, construction and household appliances industries. Inorganic production included, among others: hydrochloric acid, sodium hypochlorite, sodium hydroxide.

On June 27, 2013 Zakłady Chemiczne "ZACHEM" S.A. in Bydgoszcz changed its name to "Infrastruktura Kapuściska" S.A. Change of name of Zakłady Chemiczne "ZACHEM" S.A. to Infrastruktura Kapuściska is related to the change in the area of the Company's operations. Since then, the Company has dealt with the management of infrastructure and the supply of utilities to business entities.

December 7, 2013 Infrastruktura Kapuściska S.A. ceased production of chemical organic and inorganic substances. Since then, the company's activity has focused primarily on the provision of services related to infrastructure management and the supply of utilities to entities operating in the vicinity of Infrastruktura Kapuściska. On 30 December 2013, the Company's Management Board filed a bankruptcy petition with the court due to the loss of financial liquidity.

By the decision of March 14, 2014 in the case with reference number XV GU 95/13, the District Court in Bydgoszcz declared Infrastruktura Kapuściska joint-stock company bankrupt with its registered office in Bydgoszcz, i.e. the legal successor of Zakłady Chemiczne "ZACHEM"  joint-stock company. Since then, the Company has been represented by the bankruptcy trustee.

In March 2014, in connection with the bankruptcy of Zakłady Chemiczne "ZACHEM" Spółka Akcyjna, the Mayor of the City of Bydgoszcz notified the Regional Director of Environmental Protection in Bydgoszcz of environmental damage resulting from the activities conducted by the bankrupt company and its legal predecessors (ZACHEM). Subsequently, notifications in this regard were also made by Miejskie Wodociągi i Kanalizacja w Bydgoszczy Spółka z o.o. and the bankruptcy trustee of Infrastruktury Kapuściska S.A.

On October 24, 2014, the reciver of Infrastruktury Kapuściska S.A. in liquidation bankruptcy, sold, among others: plots of land including: General Waste Landfill and a hazardous waste (pophenol sulphite) landfill, as well as a barrier intake installation, located on land belonging to the State Forests.

An application from the Regional Director for Environmental Protection in Bydgoszcz was submitted to the District Court in Bydgoszcz to punish the trustee in bankruptcy of Infrastruktura Kapuściska joint stock company in liquidation bankruptcy for failure to agree with the environmental protection authority on the conditions for remedial actions in the area of the "Zielona" industrial waste landfill complex.

Commissioned by the City of Bydgoszcz, GEOPROGRAM Wojciech Andrzejewski carried out tests in 5 selected individual wells in the Łęgnowo-Wieś housing estate. Water testing at Toruńska 422 street indicated the presence of aniline and toluidine, while at Przyłubska 20 street - increased content of total organic carbon as well as bicarbonates and zinc.

On January 10, 2017, an agreement was concluded with the AGH University of Science and Technology in Kraków for the development of a "Draft plan for the remediation of the "Zielona" industrial waste dump on the site of the former Zakłady Chemiczne "ZACHEM" S.A. in Bydgoszcz and the remediation of the soil and water environment in the area of landfill impact”.

In the fourth quarter of 2017, scientists from the AGH University of Science and Technology in Kraków conducted research in 53 wells and surface waters as part of the WODA+ research project. As a result of these studies, phenols were detected in 31 of the 53 wells. The presence of toluene was found in 6 wells and increased content of total organic carbon in 18 wells. In 35 cases, excessive concentrations of metallic elements (mainly iron, zinc and manganese) were found.

On January 23, 2018, the Regional Director for Environmental Protection in Bydgoszcz, by way of a decision, imposed on the trustee in bankruptcy of Infrastruktura Kapuściska joint stock company in liquidation bankruptcy the obligation to carry out preventive actions consisting in activating the barrier intake and securing the hazardous waste landfill located at Zielona Street.

On June 22, 2018, the National Fund for Environmental Protection and Water Management and the Regional Directorate for Environmental Protection in Bydgoszcz concluded an agreement for co-financing the project entitled "Remediation of polluted areas in the area of the former "ZACHEM" in Bydgoszcz in order to eliminate health and environmental hazards, including the Natura 2000 area of the Lower Vistula Valley and the Baltic Sea. The project is to be implemented in the years 2018-2023, and its planned total cost is PLN 93,425,000, including PLN 79,411,250 from the European Funds.

After signing on June 22, 2018, an agreement for co-financing the project entitled "Remediation of polluted areas in the area of the former "ZACHEM" in Bydgoszcz in order to eliminate health and environmental hazards, including the Natura 2000 area of the Lower Vistula Valley and the Baltic Sea", preparations for launching the proper remediation process have begun. Among other things, As part of the baseline study, holes were drilled to drain and inject them, and to monitor their condition.

On October 6, 2020, the Regional Directorate for Environmental Protection in Bydgoszcz signed a contract for pilot activities for the task "Design and construction of installations for the purposes of cleaning, together with remediation activities" implemented as part of the Project "Remediation of contaminated areas in the area of the former ZACHEM" in Bydgoszcz in to eliminate health and environmental threats, including the Natura 2000 area of the Lower Vistula Valley and the Baltic Sea”

On January 19, 2021, the Regional Directorate for Environmental Protection in Bydgoszcz signed an implementation agreement with the Polish-French consortium of Remea limited liability company, Remea Societe par actions simplified a associe unique and Menard limited liability company for the construction of an innovative remediation installation. The construction of the installation took over half a year.

The project of remediation of polluted sites in the area of operation of the "Zielona" industrial waste landfill complex of the former "ZACHEM" joint-stock company in Bydgoszcz, implemented by the Regional Directorate for Environmental Protection in Bydgoszcz, has entered its target phase, i.e. in 2021 we started water purification underground and land.

On July 6, 2023, the Regional Director for Environmental Protection in Bydgoszcz signed an agreement for the continuation of remediation activities under the Project entitled "Remediation of polluted areas in the area of ​​the former Z.Ch. "ZACHEM" in Bydgoszcz in order to eliminate health and environmental hazards, including for the Natura 2000 area of ​​the Lower Vistula Valley and the Baltic Sea" co-financed by the Operational Program Infrastructure and Environment 2014-2020. Due to the threat to human health and the condition of the environment, including the Natura 2000 area of ​​the Lower Vistula Valley, posed by the cloud of pollution from the "Zielona" landfill complex, it is necessary to carry out further remediation actions - says Szymon Kosmalski, Regional Director of Environmental Protection in Bydgoszcz. The actions planned to be implemented will focus primarily on maintaining the already achieved ecological effect in the form of class III groundwater quality in accordance with the Regulation of the Minister of Maritime Economy and Inland Navigation of October 11, 2019 on the criteria and method of assessing the status of groundwater bodies and standards quality for class III soils in accordance with the Regulation of the Minister of the Environment of September 1, 2016 on the method of assessing land surface contamination. In addition, the treatment will allow the removal of an additional load of pollutants from the foreground of the above-mentioned complex of landfills in the amount of not less than 2 Mg/month of polluting organic substances, characterized by the parameter TOC (Total Organic Carbon) and not less than 150 kg/month of toxic phenols. Activities under the OPI&E project are planned until the end of 2023.
