Waste Materials
Regular waste at the headquarters building is
processed with recycling and compost. The output in
2015 was 90,285 tons. On construction principles, we
minimize the production of waste materials within the
site range, sufficiently utilize natural resources, and
set waste reduction goals for enhanced management
and prevention of excessiveness. Waste that can
be produced on construction sites include garbage
from living quarters, harmless construction waste
materials, hazardous waste, waste soil, and materials
from structure demolition. Regular garbage and
waste that can be removed or processed with regular
waste materials are collected and sorted on-site,
stored in appropriate containers, and then handled
by city cleaning squadrons. For waste soil, hazardous
industrial waste, and toxic substances, CTCI contracts
qualified and legal waste service providers. CTCI
confirms the appropriateness of the final disposal
of waste materials to prevent secondary pollution.
Chemicals and oils are not stored on construction
sites, and the storage of toxic substances is minimized
when inevitable.
For radioactive industrial waste, appropriate
protection is applied based on intensity and level of
risks to prevent human exposure. Precautions are
taken to prevent suspended particulates, fallout,
and rain water runoff. When the transportation and
storage of toxic substances are necessary, labeling
and isolated storage are stringently required. In
terms of toxic substance leakage prevention plan
and emergency response measures, CTCI regularly
conducts reviews and adjustments based on actual
situations and performs regular drills, inspections, and
examinations. In the event of large-scale leakage of
toxic substances, we immediately take emergency
response measures, report to the highest commanding
officer, and notify local environmental agencies within
the time limit prescribed by law.

Note 1: Only domestic data are available for construction sites in 2013 and 2014.
Note 2: Construction site data in 2015 include domestic and overseas data.
Note 3: Waste from construction (concrete/ bricks) mainly consists of demolished concrete. The measurement on-site is cubic meter; The measurement in tons is based
on an average density of 2.5 ton/cubic meter.
Note 4: The goals were to remain below the average of the previous two years.

Note 1: The construction site resources recycling statistics in 2013 include paper, glass, plastics, and metal cans.
Note 2: The construction site resources recycling statistics in 2014 and 2015 include only paper.
Note 3: The construction site resources recycling statistics in 2015 include only paper and include both domestic and overseas amounts, hence the significant increase.
