Addressing Global Warming

Lintec Group's thinking the domestic Lintec Group is committed to carrying out various environmental activities to mitigate global warming, climate change and other environmental issues that impose risks on the continuity of its business.

Efforts in Manufacturing

Status of Compliance with Japan's Energy Conservation Law

Energy use by the entire Lintec Group in Japan* exceeds 1,500 kl of crude oil equivalent each year. As a result, the Group was designated as a "specified business operator", pursuant to the provisions of the Act on the Rational Use of Energy ("Energy Conservation Act") in Japan, and is required to improve its energy use per production unit as well as its weighted electricity use per production unit (for reducing peak hour demand) by 1% per year. In fiscal 2018, the Lintec Group in Japan implemented a variety of energy-saving measures, such as effective operation of production facilities and boilers, management of the air-conditioning system, recovery and use of waste heat, and use of VOC combustion heat.

Energy Savings Promotion Committee

To comply with the Energy Conservation Act, the Lintec Group in Japan collects monthly data on energy consumption of individual sites under the direction of the Lintec Energy Savings Promotion Committee. In fiscal 2018, the Lintec Group in Japan implemented corporate-wide energy-saving measures aimed at improving its energy use per production unit. The Mishima Plant (Doi Plant) and Kumagaya Plant updated heat medium boilers (equipped with economizers).

Total Energy Use and CO2 Emissions

In fiscal 2018, total energy use (crude oil equivalent, covered by the Energy Conservation Act) for the Lintec Group in Japan increased by 0.2% from the previous year due to an increase in production volume. Energy use per unit of production improved by 1.8% to 0.3114 kl per ton. CO2 emissions were 179 thousand tons, down from 186 thousand tons in fiscal 2017. In fiscal 2019, Lintec aims to reduce its CO2 emissions and electricity consumption by 1.0% each on a per-unit of production basis compared to fiscal 2018, by facilitating the use of low-carbon electric power.

  • ※1The amount of CO2 emissions is calculated by applying a CO2 emission coefficient to the amounts of electricity and fuel used.
  • ※2The CO2 emission coefficient for fiscal 1990 is the value specified in Article 3.1 of the Enforcement Order for the Act on Promotion of Global Warming Countermeasures in Japan as revised in December 2002. The CO2 emission coefficients for fiscal 2009 and thereafter are the values specified in the same Order, as revised in March 2010. For the purchased electricity coefficients Lintec uses the emission coefficients provided by the power companies that supply electricity to the facilities concerned.
  • ※3The emissions shown above are CO2 emissions from fossil fuels.

Solar Power

Lintec has used photovoltaic technology full-scale. An approximately 1,000 kW system was installed on all the rooftops at the Doi Plant and began operation in January 2013. In March, an approximately 500 kW system was installed and began operation at the Agatsuma Plant. The two systems will reduce O2 emissions by about 500 tons per year. In addition, a smaller system has been installed in the Head Office building to supply power for internal use, thereby helping reduce on-peak demand.

Efforts to Reduce CO2 Emissions: Fuel Shift to LNG

From fiscal 2006, Lintec moved forward with the conversion of fuel for boilers used to produce steam, shifting from heavy oil and kerosene to utility gas and LNG, which have lower CO2 emissions. In January 2011, fuel conversion work for boilers at Lintec's plants in Japan had been completed. In addition, we are promoting installation of economizers in incinerator boilers and use of waste heat recovered from VOC treatment units. Seeking to further enhance our energy-saving efforts directed at reducing CO2 emissions, we adopt energy-efficient models when updating facilities while promoting efficient operation of equipment and use of residual heat.

In 2018, the Kumagaya Plant updated the non-utility generation facilities (gas engine) to be able to increase energy efficiency in response to changes in the electricity and steam demand ratio.

Introduction of Cogeneration Systems

Lintec has introduced cogeneration systems that produce and supply electric power and heat from the heat source.

The Kumagaya Plant and Doi Plant have introduced gas engine cogeneration systems, which use LNG and other types of fuel, generate and supply electric power to operate various production facilities, and collect, using steam, and utilize heat generated at the time of power generation.

The system at the Kumagaya Plant started its full-fledged operation in April 2018, reducing emissions by approximately 4,100 tons CO2/year compared with the previous fiscal year. At the Doi Plant, the system started its full-fledged operation in October 2018, and it is expected to reduce emissions by approximately 4,000 tons CO2/year.

Reducing Power Used for Lighting

The Lintec Group continuously encourages energy-saving activities. These include visualization of energy use, air-conditioning control, reduction of standby energy use during non-business hours, and introduction of LED lighting. At the Ina Technology Center, LED lights were introduced in 2018 to replace fluorescent lighting.

Efforts to Prevent the Leakage of Fluorocarbons

Manufacturing sites are equipped with a number of industrial chillers and air conditioners that use fluorocarbon refrigerants. The Lintec Group, in compliance with the Fluorocarbons Emissions Control Act, creates a list of such equipment installed at its sites and conducts daily checks and periodic detailed inspections in order to prevent the leakage of fluorocarbons from the equipment during operation.
When needing to dispose of the equipment, we entrust the task to appropriate service providers to ensure safe recovery of the compounds contained.
