Consulting

Based on our experience handling more than 1,000 soil survey and cleanup cases every year, we employ methods that are optimized to meet customers' budgets and land-use needs. Our extensive experience providing these services even includes government organizations.

Put simply, soil contamination conditions and measures vary widely from case to case.
Soil surveys may be carried out as part of land transactions, as part of independent surveys of factories and similar for corporate social responsibility reports, in response to requirements under the Soil Contamination Countermeasures Act and other laws and regulations when discontinuing the use of a factory, and for many other possible reasons.
As an example, take the case of a legally stipulated land transaction: Soil survey operations may involve the government, the seller and buyer, financial institutions, intermediary corporations, and many other parties.
In this scenario, each participant has differing levels of experience with soil contamination, and their needs vary as well. Daiseki Eco. Solution takes consideration of such diverse needs in order to design a survey plan tailored to each unique situation.
In addition, accounting standards for asset retirement obligations and other areas related to contaminated soil underwent numerous changes upon enactment of the April 2010 revisions to the Soil Contamination Countermeasures Act, and conforming to these changes requires considerable knowledge and experience.
Consulting services in this area require government-related procedures, experience serving customers in response to changes and singular needs, a wide-reaching network, and the capabilities required to make proper changes.
Here at Daiseki Eco. Solution, we have experience creating and implementing vast numbers of soil contamination measures around the nation prior to enactment of the Soil Contamination Countermeasures Act, and through this experience we have fostered large numbers of a seasoned sales and technical staff waiting to fulfill customer needs based on reliable approaches and frameworks.

New Measures

Conversion into Cement Base Material

Contaminated soil brought in to our recycling center, which has a 1.3-million-ton annual processing capacity, is put through various processes including classification, kneading and mixing to convert it into a base material for cement production. This material is sent to our cement plant, where Portland cement and other types of cement are made.

Cleanup
Cleanup

Aqueous cleaning is utilized to separate heavy metals and other substances from contaminated soil, and then the particulate content from contaminated soil and the purified soil are separated from one another.

Extraction via Chemical Desorption
Extraction via Chemical Desorption

Soil contaminated with volatile organic compounds, or VOCs, is extracted via chemical desorption, leaving clean soil behind. Soils which have had their VOCs removed in this manner can be reused as backfill—a method that is increasingly popular as a highly effective recycling method.

Extraction via Magnetic Screening
Extraction via Magnetic Screening

Heavy metals are separated from contaminated soil via iron-powder-based adsorption, and the heavy metals and iron powder is recovered using magnets. After that, these are separated into purified soil and contaminated soil in concentrated form.

Onsite Purification and Processing
