環境への取り組み|株式会社栗田機械製作所

環境への取り組み

Since its foundation in 1930, Kurita has been supporting production processes of its customers as well as attempting to conserve the global environment. By providing its machines to its customers and efficiently maintaining its organization, Kurita has been addressing three challenges to help conserve the global environment.

What we can offer to our customers

We will make further efforts in designing machines that help save electricity consumption and manpower. Also, we will propose improvements for existing Kurita machines.

Ex.: Comparison of squeezer with vacuum dewatering machine in producing bean jam.PDFPDF

What we reflect in operating our organization

Annual electricity consumption 65,268 kW/h will be reduced to 14,400 kW/h in 5 years.

We have already been conscious about electricity consumption in our factories and offices. In 2011, we developed a 5-year project according to which we will eventually supersede existing lighting equipment with new, low consumption equipment.

We are now operating a total of 23 cars for sales and machine installation activities. We will supersede gasoline cars (1500 cc to 1800 cc classes) with hybrid vehicles. At the end of 2015, we will be operating hybrid vehicles only. The amount of CO2 emissions 5 years later by this effort will amount to 53.82 t annually.

Effort to reduce CO2 emissions by introducing PRIUS

Possible reduction in CO2 emissions by superseding Carolla Fielder with PRIUS.

1 year 2 year 3 year 4 year 5 year
Reduction (t) 2.34t 4.69t 7.03t 9.36t 11.7t

(Calculation is executed under assumption that fuel consumption is 80% as much as that in 10-15 mode, and the car travels for about 20,000 km annually.)

Record of replacement in Kurita Machinery

In June 2010, one gasoline car was replaced. Carolla to PRIUS 11 months after replacement 2.145t Reduction in progress
In January 2011, one gasoline car was replaced. WINGROAD to PRIUS 4 months after replacement 0.78t Reduction in progress

As of April 2011

What we can offer to our customers

Even if having undergone operation for 50 years or 60 years, Kurita’s filter presses will further remain operative after overhaul work.

We are proposing to our customers overhauling programs for their machines.

Even if having undergone operation for 50 years or 60 years, Kurita’s filter presses will further remain operative after overhaul work.

Certain users have been operating time-honored manual machines of Kurita after modifying them into semi-automatic machines.

If a customer wants us to take in its machine, we will propose a withdrawal program including recycling scheme.For details, click here.

What we reflect in operating our organization

Environmental conservation in Asia

In fabricating machines, we are making efforts to avoid occurrence of wastes and recycle any materials.
We will recycle the main bodies of used Kurita filter presses recovered in Japan, and deploy them to help conserve the environment in Japan.

What we can offer to our customers

Our filter presses have already been utilized to recover rare metals and remove harmful substances. The intended harmful chemical substances to be removed are environment-related chemical substances covered in RoHS directives, lead and its compounds, hexavalent chromium, cadmium and its compounds. Kurita’s filter presses are conveniently used in certain processes that recover or remove substances A within environment-related substances to be controlled, that is, cadmium and its compounds, hexavalent chromium compounds, lead and its compounds, mercury and its compounds, bis(tributyl tin) oxide (TBTO), tributyl tins (TBTs) and triphenyl tins (TPTs); as well as substances B within environment-related substances to be controlled, that is, antimony and its compounds, arsenic and its compounds, beryllium and its compounds, bismuth and its compounds, nickel and its compounds, selenium and its compounds, magnesium and its compounds, copper and its compounds, gold and its compounds, palladium and its compounds, silver and its compounds, lead and its compounds, mercury and its compounds, bis(tributyl tin) oxide (TBTO), tributyl tins(TBTs), and triphenyl tins (TPTs).

What we reflect in operating our organization

年間電力消費量を5年間で約80%削減

In fabricating machines used to manufacture industrial products, we verify that procured components possibly coming into contact with products do not contain environment-related substances covered by RoHS directives. After safe treatment, we dispose of customer-supplied slurry having undergone experiment in Kurita
