Resource-circulating Society

We are proactively working to reduce waste and water consumption in cooperation with tenants and building management companies toward the realization of recycling society. For reconstructing buildings, we endeavor to reduce environmental impacts by promoting the 3R (reduce, reuse, and reycle) through the adoption of Longer Life Building designs that enable to reduce waste significantly and effectively utilizing resources.

Resource-saving and Reduction of Waste in Buildings Owned by Hulic and Reconstruction of Buildings

Hulic Group has worked on reduction in the amount of waste disposal and water usage in cooperation with tenants and building management companies.
We install toilets that reuse water and various water conservation systems in many buildings. Water saving toilets and wash basins are now standard in buildings Hulic already owns.

Amount of Waste Disposal and Water Usage at Hulic's buildings

As a result of our steady efforts to create a resource-circulating society, we managed to reduce waste generation by 12% and water usage by 25%. (Percentage reductions calculated per total floor area compared between the average of four years from 2013 to 2016 and the average of three years from 2005 to 2007)

Promotion of the 3R

Efforts to Reduce

We realized environmental advantages by making efforts to curb the amount of waste disposal and CO2 emissions during reconstruction, for example, by adopting buildings which can be in service for 100 years or longer as standard specification(*) with an eye to saving resources. The Gate Hotel Kaminarimon by Hulic (Hulic Hotel Management) is reducing the amount of garbage by biologically processing raw garbage from the restaurant.

*In the case of a building with a Long Life of 100 years, the amounts of waste generated and resources used in reconstruction works can be reduced 50% or more, compared to the conventional case of reconstruction every 40 years (standard proposal). A Long Life design was used for all of the buildings that were completed or started in fiscal year 2014.

Efforts to Reuse

We launched the book donation program, which started based on suggestions from employees. In this program, we donate the proceeds from selling used books collected from group employees to Shanti Volunteer Association, which provides educational and cultural support to children in Asia through the external used book dealer. This activity contributes to reducing waste and helps to address the poverty issue.

Efforts to Recycle

As recycling efforts through daily business activities, we started to recycle used paper and printer toner cartridges. We will continue to work on those efforts to support the achievement of the resource-circulating society.

Trends in the amount of used paper recycled(*)

(Unit: Kg)

Fiscal year FY2015 FY2016 FY2017 FY2018
Recycled amount 8,180 9,400 11,365 13,125

* The scope is Hulic Head Office Building.

Prevention of Pollution

The Company considers that the minimization of environmental pollution due to business activities is indispensable to realize a recycling society. Thus, we have worked on the reduction of emission of pollutants, including CFCs and PCBs with the cooperation of design companies and construction companies, as well as endeavoring to adopt construction methods that reduce pollutant discharge as much as possible.
In addition, we have collected data of SOx, NOx, VOC and toxic waste generated from reconstruction activities in the past and identified the amount of those substances generated.

Amount of emission of SOx, NOx and VOC in the past three years

2016 2017 2018
SOx emissions (kg) 62 42 0.05
NOx emissions (kg) 418 281 -
VOC emissions (kg) - 51 151

* Figures are only for reconstructed buildings completed in each year and for which data were collected.

Effective Utilization of Water in Buildings Owned by Hulic

In order to reduce the amount of water consumption in buildings owned by Hulic, we have taken the initiative of putting water-saving devices on water taps installed in the plumbing of existing buildings owned by Hulic. Installing a water-saving device can save about 40% per tap. In addition, we are introducing water-saving toilet bowls and sinks into the existing buildings owned by Hulic as the standard type.

Efforts toward Recycling of Water

We are engaged in not only the reduction of water consumption, but also the recycling of water in buildings owned by Hulic. In Hulic Setagaya, completed in 2014, we made efforts toward effective utilization of limited water resources by reutilizing rain water for sprinkling and washing for toilets.

Implementation

Adoption of the PC Method

From the standpoint of a business owner, we proactively adopt the PC method (*), which can significantly reduce the amount of waste generated during construction. This method, which can shorten a construction period and minimize impacts on surrounding environments during construction, is highly appreciated in terms of longer life service of buildings. Recently, this PC method was introduced in constructing Hulic Residensce Chofu Shibasaki.

* PC (Precast Concrete) method: Precast panels produced at a plant under consistent quality control are carried to a worksite and assembled.

Effect of the PC Method

Recycling Parts of Underground Building Frames during Reconstruction

In reconstruction works, we make various efforts for reducing wastes generated in demolition works including concrete debris. For example, underground building frames of existing buildings for the Earth are used as retaining walls for the new building with new underground building frames installed inside. Of course, adequate inspections are conducted to confirm the strength when building frames of existing buildings are recycled.
After considering impacts on neighboring areas by property, we introduced the PC method into the following projects.
