We provide consulting services for the planning and establishment of:
• Material‐recycling promotion facilities (resource recovery)
• Sludge regeneration treatment centers (resource recovery)
• Energy‐recovery waste treatment facilities (heat recovery)
• Final disposal sites (landfills)

We offer end-to-end support—from the initial concept and planning stages, through facility design and construction, to post-commissioning follow-up. Through our assistance, we help advance climate-change measures such as enhanced recycling, power generation, waste-heat utilization, and reductions in greenhouse-gas emissions.

Main types of waste-related facilities we support:
• Material-recycling promotion facilities
• Sludge regeneration treatment centers (including sewage and night-soil treatment)
• Energy-recovery waste-treatment plants (heat recovery)
• Final disposal sites (landfills)

In our planning-support services, we assess local waste characteristics (composition and volume) and regional factors to recommend the optimal facility mix, capacities, and technologies.

Proper waste disposal is crucial for maintaining regional sanitation. Furthermore, efficiently recovering and utilizing heat generated from incineration can reduce carbon dioxide emissions and generate energy. Additionally, establishing appropriate final disposal sites not only improves the regional sanitary environment but also suppresses methane generation.
Our company provides comprehensive consulting services for a wide range of facilities, including material recycling promotion facilities (resource recovery), sludge regeneration treatment centers (resource recovery), energy recovery waste treatment facilities, and final disposal sites. In addition, our strength lies in our capability to provide consistent support throughout the entire process, from the conceptual planning stage of facility development to follow-up after facility completion.

We support a full range of waste‐management facility projects, including:
• General Waste Management Master Planning
(municipal solid waste, domestic sewage, disaster‐generated waste)
• Site‐Selection Surveys
• Basic Concept and Detailed Planning for Waste‐Treatment Facility Development
• Environmental Impact Assessments and Living‐Environment Surveys
• PFI/PPP Introduction Feasibility Studies
• Facility‐Development Advisory Services
• Design Supervision and Construction Management
• Operations Monitoring (DBO, PFI, etc.)
• Facility Life‐Extension Projects
• Combustion‐Plant Decommissioning

Through our consulting services for the planning, development, and operation of waste-related facilities, we:
• Promote resource recovery
• Reduce CO₂ emissions by power generation at WTE plants
• Decrease final disposal volumes
• Ensure proper treatment of hard-to-recycle wastes
