Category C. Concrete materials

1. Purpose of Establishing Certification Criteria
In civil engineering/construction-related business that is implemented as part ofsocial infrastructure development, ripple effects in the economy are expected, but at
the same time a significant environmental load is imposed on the naturalenvironment of the oceans, rivers and land as well as the living environment. New
forms of civil engineering-/construction-related business based on the principles of
the “Basic Environmental Law,” such as through harmonization with the naturalenvironment, formation of a good living environment, prevention of global warming
by improving energy efficiency, etc., are therefore being explored.
In addition to these kinds of environmental conservation efforts, it was also
determined that in the civil engineering/construction-related business it is necessary
to promote the control of waste generation (reduction), secondary uses (reuse) andrecovery for further use (recycling) in accordance with the “Waste Disposal and Public
Cleansing Law,” the “Basic Law for Establishing a Recycling-Based Society,” the “Law
Concerning Promotion of the Procurement of Eco-friendly Goods and Services by theState and Other Entities (Green Procurement Law)” and the “Law for Recycling
Materials for Construction (Construction Recycling Law).” Furthermore, independent
efforts by civil engineering/construction enterprises for reduction of theenvironmental load, the “Guidelines for Green Procurement in the Construction
Industry” were formulated in 2002.
In Japan’s material balance, the proportion attributable to civil engineering andconstruction-related business accounts for approximately 40% of new resources (2002White Paper on a Recycling-Oriented Economic System; FY2001 Major Construction
Materials Demand Forecast), approximately 20% of industrial wastes andapproximately 40% of wastes collected at final landfill sites (2002 Environmental
White Paper). It can therefore be expected that an environmentally-sound materials
cycle to promote reduction, reuse and recycling will have a major impact on the
structure of society.
The load placed on elements of the environment by the civil engineering andconstruction-related business varies according to many environmental factors suchas the site of the business and the methods and types of materials used. As theenvironmental load may be reduced by applying Eco Mark Product Certification to
construction materials, one of the factors affecting this, the Eco Mark Certification
Criteria for newly applied products, shall be established to certify such materials as‘construction products’ after organizing and integrating them with products that are
already certified.

1

131V1 Criteria C
The new certification criteria, in addition to minimizing the consumption of newmaterials and the generation of wastes on the basis of using recycled materials, as
has been recommended, and taking into consideration the reduced use of hazardous
substances, energy saving, the impact on the ecosystem, etc., that are intended toreduce the environmental load imposed by construction work and long-term use, bothof which may be characteristic of construction products, aim at the same time toachieve a symbiotic relationship with nature by creating a secondary naturalenvironment. The concept of the life cycle of materials and products will be introduced
into the evaluation, taking into consideration the life stage when the construction
work is commenced as a construction product, and as many concrete environmentalload items as possible have been selected.
