Used oils (code 01.3), Chemical wastes (code 01.4, 02, 03.1) and Health care and biological wastes (code 05) – in NACE sections G – U excl. 46.77 combination of data reported by waste producers/holders and waste treatment facilities were used. The difference in quantities reported by waste treatment facilities and waste producers/holders were taken into consideration. By checking the coverage of the companies that reported data into the EPR, it was determinated that there are significant number of small enterprises, which do not exceed the annual threshold of 500 kg of hazardous waste, so they are not obliged to report data into the EPR. Therefore, the above-mentioned difference was added to those NACE sections G – U excl. 46.77.

Metallic wastes, ferrous (code 06.1) and non-ferrous (code 06.2) – in NACE section F the combination of data reported by waste producers/holders and estimations were used.

Rubber wastes (code 07.3) – in NACE sections G – U excl. 46.77 the combination of data reported by waste producers/holders and waste treatment facilities were used. The difference in quantities reported by waste treatment facilities and waste generators were taken into consideration. It was not possible to distinguish quantity of rubber wastes, which originate from class 46.77, households and services sector, so the sections G – U excl. 46.77 include amounts from services sector and amounts from households and class 46.77. By checking the coverage of the companies that reported data into the EPR, it was determinate that there are significant number of small enterprises, which do not exceed the annual threshold of 500 kg of hazardous waste, so they are not obliged to report data into the EPR. Therefore, the above-mentioned difference was added to those NACE sections G – U excl. 46.77.

Discarded vehicles (code 08.1) – in NACE sections G – U excl. 46.77 and HH (households) data reported by waste producers/holders and waste treatment facilities. This assumption was made based on the information on origination of discarded vehicles provided by waste treatment facilities. In NACE section A the estimations were used. According to the information given by one big waste collector in Croatia, only 1% originates from Agriculture, hunting and forestry.

Batteries and accumulators wastes (code 08.41) – in NACE sections G – U excl. 46.77 the combination of the data reported by waste producers/holders and waste treatment facilities were used. The difference in quantities reported by waste treatment facilities and waste generators were taken into consideration. The difference between those sources were added to services sector although part of the amount possible may originate from households. It was not possible to distinguish precise shares from commerce and households.

Animal and mixed food waste (code 09.1) – in NACE section C10 – C12 data on animal tissues were determinate on the basis of data reported by biogas plants to the Ministry of Agriculture and data reported into the database EPR. In NACE sections G – U excl. 46.77 the combination of the data reported by waste producers/holders, waste treatment facilities and data by Ministry of Agriculture were used. The difference in quantities reported by waste treatment facilities and waste generators were taken into consideration.

Mixed and undifferentiated materials (code 10.2) – in NACE section F the combination of data reported by waste producers/holders and estimations were used. Amounts produced by construction and demolition activities, which were reported in all economic sections except in section F, were allocated to section F.

Mineral waste from construction and demolition (code 12.1) and Soils (code 12.6) – in NACE section F data were based on the estimation. For the purpose of improving the data quality concerning waste from NACE activities Mining and quarrying (B) and Construction (F), MESD/Institute implemented the project "Improvement of data flow and data quality regarding construction waste and waste from the exploration and exploitation of mineral raw materials".

Other mineral waste (code 12.2, 12.3, 12.5) – in NACE B and NACE F data were based on data reported by waste producers/holders and estimations. For the purpose of improving the data quality concerning waste from NACE activities Mining and quarrying (B) and Construction (F), MESD/Institute implemented the project "Improvement of data flow and data quality regarding construction waste and waste from the exploration and exploitation of mineral raw materials".

Glass wastes (code 07.1), Paper and cardboard wastes (code 07.2), Plastic wastes (code 07.4) and Wood wastes (code 07.5) – in NACE sections G – U excl. 46.77 the combination of data by waste producers/holders and waste collectors were used. The difference was taken into consideration. The difference between those sources was added to services sector although part of the amount possible may originate from households. It was not possible to distinguish precise shares from commerce and households.

Discarded equipment (excl. discarded vehicles, batteries/accumulators) (code 08 excl. 08.1, 08.41) – in NACE section HH (households) the combination of data reported by waste producers/holders and waste collectors were used. Regarding data on household waste, from 2017 new EPR reporting forms have been introduced (see Determination of waste generation in the economy on the basis of administrative sources).

Household and similar wastes (code 10.1) – in NACE sections G – U excl. 46.77 the combination of data reported by waste producers/holders, waste collectors, waste treatment facilities and estimations were used (see Determination of waste generated by households).

Determination of waste generation in the economy was mostly done based on the data reported by waste generators, waste collectors and waste treatment facilities into the EPR database. Provisions of the Act on Sustainable Waste Management (OG No 94/13, 74/17, 14/19, 98/19) and Ordinance on Environmental Pollution Register (OG No 87/15) stipulate reporting of the annual data for 2020.

Companies report EPR data via Internet by means of user name and password that are assigned by the MESD/Institute. The deadline for reporting is 31^st of March current year for the previous calendar year. From 31^st of March until 15^th of May, 20 county offices and the office of the City of Zagreb in cooperation with the competent inspection ensure the checking of data in terms of their completeness, consistency and credibility. The MESD/Institute coordinates activities relating to data quality assurance and control.

Waste generators producing more than 500 kg of hazardous waste and/or more than 20 tonnes of non-hazardous per a year are obliged to report annual data on registration form NO (Registration form for producer/holder of produced waste). Reporting forms for waste generators require view of the chain of movement of waste, from the place of generation to the waste collector or place of final recovery/disposal.
Industrial waste collectors report data on registration form SO-2 (Registration form for waste collection). Except general data on waste collector, form SO-2 require for each type of waste data on collected amounts of waste and data on locations to which collected waste is forwarded.

Municipal waste collectors report data on the registration form SO-1 (Registration form for municipal waste collectors), while civic amenity sites and waste dealers on the registration form SO-3 (Registration form for amenity sites/mobile amenity sites and waste dealers). Registration forms require view of the chain of movement of waste, from the place of generation (collection) to another waste collector or place of final recovery/disposal. For each type of waste, municipal waste collector has to report town/municipality from which waste originates, amount collected from households, from amenity sites etc., location to which collected waste is forwarded. In case of mixed municipal waste, the number of inhabitants covered by collector’s service has to be specified.

Waste treatment facilities (including landfills) report data on registration form OZO (Registration form for waste recovery/disposal). Form OZO contains general data about the operator, data about amounts for each waste type taken in the reporting year (from the territory of Croatia and imported from another countries separately), data about temporary storage, waste handling (amounts of waste regarding disposal and recovery procedures) etc.

As some bio-plants and incineration plants for animal by-products in 2020 still didn’t obtain waste management permit according to the Act on Sustainable Waste Management (OG No 94/13, 74/17, 14/19, 98/19), part of amounts of animal by-products not intended for human consumption were determined on the basis of the data collected by Ministry of Agriculture. This Ministry is responsible for issuing approvals of temporary storage, incineration and co-incineration of animal by-products, and approvals of intermediate plants, biogas plants and composting plants, which take over animal by-products.

Coverage of waste statistics with regard to extractive waste¹⁾

1) Please mark with an X whether the listed materials are completely covered, partially covered or generally excluded from waste statistics.

Tailings aren’t covered because in Croatia there is no ore excavation. It is carried out the exploitation of technical building stone, architecturally building stone, building sand and gravel and hydrocarbons.

Determination of discarded vehicles amounts originating from households was based on the data reported by waste treatment companies (see Annex 5). For other waste types generated by households amounts are based on the reports provided by municipal waste collection companies, civic amenity sites and waste dealers.

Household and similar wastes (code 10.1) – mixed municipal waste – data on generated amounts of mixed municipal waste by NACE activities were estimated. According to the information given by municipal waste collectors, about 82,7% of produced mixed municipal waste (LoW 20 03 01) originates from households while the rest (17,3%) is produced by economic activities. This 17,3% of totally produced amount of mixed municipal waste was divided with the number of employees in economic activities which resulted in an average ratio of generation of mixed municipal waste per employee and per year. This average was multiplied with number of employees in each NACE activity.

Estimated amounts of produced mixed municipal waste per economic activities are questionable quality mainly because of unregistered number of employees especially in touristic season in services providing accommodation, food preparation and serving which make a significant share in economy.

Data on municipal waste include amounts of municipal waste generated by tourists.

Relevant waste treatment facilities are identified through WMPR database, run by MESD/Institute. This database contains information and documents on waste management permits. Competent authority for issuing waste management permits for hazardous waste management, permits for thermal treatment of non-hazardous waste, registers for carrying out waste management operations is Directorate for Environmental Impact Assessment and Sustainable Waste Management within the MESD. For all other types of waste competent authorities are county offices and City of Zagreb office. MESD/Institute upon the issuing a permit receives a copy and on the daily bases data are entered into the WMPR database. Waste management permits provide various data, like data on recovery/disposal operations, annual capacities of treatment facilities, etc. The coverage of treatment facilities by WMPR database is almost 100%. For providing data on number and capacities of treatment facilities several sources were used. Most of the data were extracted from WMPR database. In certain number of cases data on capacities from EPR database were used or were obtained contacting directly waste treatment facilities. Only the data on number and capacities of biogas plants and incinerators for animal by-products were partially collected by Ministry of Agriculture as all of this plants didn’t obtain permits according to the Act on Sustainable Waste Management.

Data were mostly reported by waste treatment facilities into the EPR database according to the procedure described in section Determination of waste generation in the economy on the basis of administrative sources. Only part of the data on animal by-products treated in biogas plants and incinerators were collected by Ministry of Agriculture. In Croatia there is only one rendering plant of open type. It is the largest animal by-products processor and the majority of the animal by-products generated in Croatia are treated in this company. One of the results of that treatment process is technical fat. In 2020, there wasn’t any incineration of technical fat.

Data on rest capacity of landfills were determinated on the base of the data reported by landfill operators into the database Central Management System for the Data on Landfills of Waste.

The Environmental Pollution Register (EPR database)

Continuous data entry.

Annualy - data is submitted twice a year within 30 days of the expiry of each half-year period.

Annualy - deadline for reporting is 1^st of March for previous year.

NACE 19 – Performed validation rule showed that in 2020 there was less hazardous waste than in 2018. It is about LoW 05 01 06* (oily sludges from maintenance operations of the plant or equipment) generated within the process of cleaning the tank in 2018 and 05 01 11* (wastes from cleaning of fuels with basis) due to the refining oil with a higher sulfur content in 2018 from oil industry. Those activities are not performed in 2020.

Performed validation rule showed deviation in NACE C13-C15. There was less total waste in 2020 than in 2018 due to reduced economic activity of this sector (LoW 04 01 01 fleshings and lime split wastes). In 2020 it is recorded reduced number of employees comparing with 2018. Hence, the estimated amounts of mixed municipal waste for which calculation is made on the base of number of employees are reduced. Slight increase of hazardous amounts is related to remediation of pollution with fuel oil (LoW 13 07 03* other fuels, including mixtures) on the location of one textile industry.

Performed validation rule showed deviation in NACE 46.77. There was more total waste in 2020 than in 2018 due to increased activity of metal waste traders.

f.1)   generation (largest differences for inner cells)

Regarding data on household waste, from 2017 new EPR reporting forms have been introduced (see Determination of waste generation in the economy on the basis of administrative sources). New reporting forms require more detailed data on waste origin, hence data on produced waste by households are more accurate than previous years and significantly differ from previous years. Consequently, data on waste from service sector also significantly differ for some waste categories from data for previous years.

Metal wastes, ferrous NHAZ – NACE E38 – Higher amount in 2020 than in 2018 because it depends on the quantities delivered by the producers to the factory. In addition, the collection increased due to the business increase.

Soils NHAZ – NACE F – It is about LoW 17 05 04 (soil and stones other than those mentioned in 17 05 03*) which occurs in quantities that vary over the years and according to the reporting area. Depends on the activity of the construction site – excavations.

Mineral waste from waste treatment and stabilised wastes NHAZ – NACE E38 and F – See explanation in 1.d1).

f.2)   treatment (largest differences for inner cells)

Metal wastes, ferrous NHAZ – As a consequence of the COVID-19 pandemic, on the location of one manufacturer of metal, production in 2020 was reduced (the plant operated for 2 months in 2020) compared to the previous years, and thus the total amount of waste was lower.

Metal wastes, mixed ferrous and non-ferrous NHAZ – Lower amount in 2020 than in 2018 due to the market disruptions that affected the amount of waste collected and thus recovered.

Glass wastes NHAZ – The difference in quantities was due to different production parameters of one glass factory, which resulted in higher amounts in 2020 than in 2018 and thus recovered and landfilled.

Paper and cardboard wastes NHAZ – Higher amounts due to the increased separate collection of this fraction.

Plastic wastes NHAZ – One big cement factory had an increased production and thus increased material and energy recovery. Also, separate collection of this fraction increased.

Wood wastes NHAZ – Due to the changes in the production process in one factory for manufacturing of veneer sheets and wood-based panels, recovery of this kind of waste increased in 2020.

Discarded equipment (excl. discarded vehicles, batteries/accumulators) NHAZ – Increased amount of recovered waste due to constant changes in the type and amount of EE waste that one big factory recover and adjustments of technological processes to waste that enters the recovery process.

Discarded vehicles NHAZ – In 2020, a larger quantity was reported under LoW 16 01 04* (end-of-life vehicles), which caused amount reduction of LoW 16 01 06 (end-of-life vehicles, containing neither liquids nor other hazardous components).

Animal and mixed food waste NHAZ – In 2020 there were more biogas plants operating than in 2018. Also, the reported amount of biodegradable waste from kitchens and canteens (LoW 20 01 08) due to non-compliance of waste is higher.

Vegetal wastes NHAZ – In 2020 there were more biogas plants operating than in 2018. In addition, modernization has taken place inside the one factory of old oil storage tanks.

Animal faeces, urine and manure NHAZ – There was more waste recovered. Data were checked with biogas plants and they are correct. Due to the increase of the volume of work, the amount of waste has also increased.

Household and similar wastes NHAZ – There was significant decrease of disposed mixed municipal waste due to the decreased amounts of generated mixed municipal waste in 2020. Regarding treatment processes R2-R11, data were checked and they are correct. It is about bulky waste LoW 20 03 07.

Mixed and undifferentiated materials NHAZ – Larger quantities of certain types of waste generated were related to the reconstruction and replacement of equipment in the factory since 2019 and thus more waste was recovered. The disposed amounts of LoW 19 08 01 (screenings) and 19 08 99 (wastes not otherwise specified) were lower in 2020 because in previous years, waste was handed over to the utility company for disposal, and from 2020 it was handed over to companies that recover waste.

Sorting residues NHAZ – One big cement factory had an increased production and thus increased material and energy recovery. Also, the other big factory had larger quantities recovered due to the increase in TSR, ie. replacing traditional fuels with alternative fuels. Due to the increase in separate collection, there was more amount of waste landfilled (LoW 19 12 12 - other wastes (including mixtures of materials) from mechanical treatment of wastes other than those mentioned in 19 12 11*).

Common sludges NHAZ – There was more waste recovered due to one factory started recovery of waste in mid-2019. Also, data were checked with treatment plants and they are correct. Due to the increase of the volume of work, the amount of waste has also increased.

Mineral waste from construction and demolition NHAZ – More waste was recovered due to one factory had increased waste collection and recovery capacity in their permit and there was increased number of construction sites. There was more waste landfilled in 2018 due to increased works on the sewerage network which wasn’t preformed in 2020. In addition, landfills dispose less waste each year.

Other mineral wastes NHAZ – Amounts of waste landfilled were lower in 2020 due to a change in the acceptance of certain waste in waste management centre. Mostly, it is about LoW 12 01 17 (waste blasting material other than those mentioned in 12 01 16 *) and also 10 13 04 (wastes from calcination and hydration of lime), 19 08 02 (waste from desanding).

Combustion wastes NHAZ – One big cement industry preformed energy recovery of LoW 10 09 03 (furnace slag), which was used in the production of clinker. Additionally, one big cement factory had an increased production and thus increased material and energy recovery and the other had maintenance of thermal power plant. Furthermore, one company started working in the second half of 2019.

Soils NHAZ, Mineral waste from waste treatment and stabilized wastes NHAZ – Higher amounts were recorded in 2020 due to one factory started with treatment of LoW 19 12 09 minerals (for example sand, stones). One factory started working in 2019. In addition, it depends on the activity of the construction site – excavations. In 2020, the two earthquakes affected Croatia. Also, increase in quantities for backfilling were recorded. It is about LoW 17 05 04 (soil and stones other than those mentioned in 17 05 03*) which is used daily as a cover on landfill due to continuous increase in disposal of mixed municipal waste.

For other, please see previous validation results.

Performed validation rule showed that there is more hazardous waste generated than treated. That is in line with actual state in Croatia that significant amounts are pre-treated. Also Croatia exports hazardous waste.

Performed validation rule showed that there is more non-hazardous waste generated than treated. For the purpose of improving the data quality during 2016 and 2017, the MESD/Institute implemented the project "Improvement of data flow and data quality regarding construction waste and waste from the exploration and exploitation of mineral raw materials". Within this project data on generated waste were estimated and those data were included in set 1 WStatR while data on final destination of estimated amounts are not known. In 2020, the two earthquakes affected Croatia.

Performed validation rule showed that in 2020 there was implausible combinations for treatment operation / waste categories:

EWC-Stat 12.4 (LoW 10 09 03) – R1 – Cement industry – This type of waste is used in the process of production of clinker.

Performed validation rule showed that in 2020 treated amounts were below available capacities for energy recovery (R1).

Additionally, data on special waste categories (packaging waste, waste tyres, waste oils, waste batteries and accumulators, end-of-life vehicles, waste electric and electronic equipment, waste containing asbestos) were cross-checked with data collected by EPEEF according to ordinances on special waste categories above mentioned.

By the agreement from May 2012 between MESD/Institute (ex Croatian Agency for Environment and Nature) and Croatian Bureau of Statistics, MESD/Institute took over the obligation of preparation and submitting data according to WSR to Eurostat. For the reference year 2010 and previous years those data were delivered to Eurostat by the Croatian Bureau of Statistics. Comparison of the data from those two sources is not possible because of different methodologies of data collection and processing. The CBS collected data by biannual statistical surveys while MESD/Institute uses administrative source of data.

Regarding reporting data on waste generation into the EPR database, since 2016 new thresholds are in force (500 kg of hazardous waste and 20 tonnes of non-hazardous waste). Up to 2016 thresholds for reporting data on waste generation were 50 kg of hazardous waste and 2 tonnes of non-hazardous waste. Reported data on produced waste showed that increasing thresholds in mentioned range did not significantly influenced reported amounts but reduced administrative burden in economic sector.

From 2017 new EPR reporting forms have been introduced (see Determination of waste generation in the economy on the basis of administrative sources). New reporting forms require more detailed data on waste origin, hence data on produced waste by households are more accurate than previous years.

For the purpose of improving the data quality concerning waste from NACE activities Mining and quarrying (B) and Construction (F), during 2016 and 2017, the MESD/Institute implemented the project "Improvement of data flow and data quality regarding construction waste and waste from the exploration and exploitation of mineral raw materials". Within this project estimates of waste quantities produced by mentioned NACE activities were made and those estimations were reported in reports 2016 and 2018 according to WStatR.

Detailed information on changes in amounts of generated waste, amounts of treated waste, over time are presented in the section Data Validation.
