Inklamns sulfuric sludge mixtures used in the production of cement clinkers – Ecology – News



He explained that the waste from the pond has been neutralized by mixing it with chips. This mixture remains cool in Angara, which is in the ponds, so that it can then be delivered to the Cemex plant.

According to Lielkalns, the first 2000 tons of the mixture has already been released for incineration, while already 3000 tons of garbage has been exhausted from the southern pond.

Santa Kļava, head of Cemex's environmental project department, said that the neutralized mixture produced by the Incukalns Eko global partnership is used for the production of cement clinkers, and this process is not fast.

In addition to the neutralized mass, gas and coal are added to the heating process, and thus, although the remediation works of the pond will last until 2021, Cemex intends to burn the total amount of neutralized waste until 2023, which is also the closing date for the project. is.

"It is important that there is no water, no ash in our combustion process – everything stays in the vowel at high temperatures, it is safe for the community, the environment and does not affect the quality of our product. [..] We can burn 1000 tons per month, 10,000 tons per year. We can no longer promise, "Kļava said, adding that the company must also comply with the permitted emission limit values.

In order to ensure that the pond is not kept clean, Cemex still stores its neutralized turbine from 2021 in the shops.

Director-General of the State Military Service (INV) Inga Kolegova replied in response to the question of whether it was possible to carry out the treatment of the pond faster, that it was left to the work of the performing artists.

"There are calculated flows, so somewhere, working faster, there would be no bottleneck elsewhere [dīķu teritorijā] the works will take place three years, "Kolegova said.

Speaking of the northern part of the gutter pond, Kolegova noted that there is another situation – the rubble is buried with sand. From the part of the territory, pieces of waste are removed and the rest of the contaminated soil is washed, cleaned and put back on the ground. The rest of the gutron will be burned.

The Minister for Environmental Protection and Regional Development, Kaspars Gerhards (VL-TB / LNNK), said that the current project for clearing ponds is very positive, because everything happens on time and there are work aspects ahead of the planned deadlines.

The minister indicated that the site's purification project must be time-bound, so that 80% to 70% of the total costs can be covered by the European Structural Funds. According to Gerhard, together with the first cleaning round of the area, which was carried out by the company SIA Skonto büve, the total project costs will amount to just over EUR 50,000,000.

As mentioned, the NSA officially signed a contract with the general company "Incukalns Eko" at the beginning of February of this year for the start of the rehabilitation of the Incukalns turbot ponds of 26.6 million euros. The engineering supervision of the rehabilitation activities for 1.23 million euros without VAT is in turn carried out by SIA Geo Consultants.

The entire company was founded in 2016 and its members are JSC VentEko, Eko Osta and JSC BAO.

The Cemex Broceni plant in the first incukalns sulfuric waste was incinerated in June.

It is intended that by the end of 2023 the total area of ​​the renovated land will be 2.5 hectares. The total amount of eligible funding for the implementation of specific support shall not exceed EUR 29 257 750, including the financing from the European Regional Development Fund (ERDF) – EUR 24 869 088 and the financing from public finances to 4 EUR 388 662. Of the total EUR 29.2 million, the general partnership is expected to pay 26.6 million euros for its work. The remaining 2.6 million euros is used to develop the project, and a number will be used to monitor the work of the limited liability company, the environmental monitoring of the site and other works.

After all pond renovation works in 2021, they are planned to be filled and covered with black soil, and after a further two years, a monitoring of the location will be carried out.

It was also reported that, in the event of disagreement between the VVD and the previous artist "Skonto būve", the implementation of the Incukalns project for the rehabilitation of gutters had been jeopardized. The company announced that it was not possible to complete the work related to the current resources, while the SGB refused to allocate additional funds. Instead, the VVD broke the contract with the executor and ordered the VVD to leave the project implementation site.

After the VVD signed the contract with Skonto Building, the company sued compensation of 7.6 million euros – for the work that was carried out in 2015. Meanwhile, at the end of 2016, a counterclaim was filed against Skontobuva, which was added to the claim last year and the company requested EUR 13 million from the company.

The initial completion date for the Incukalns sulfuric acid pond was at the end of 2015.
