ENVIRONMENTALLY SOUND MANAGEMENT AND DISPOSAL OF
OBSOLETE POPS PESTICIDES AND OTHER POPS WASTES IN CHINA
TERMS OF REFERENCE FOR SUBCONTRACT ON CHARACTERIZATION
OF DIOXINS RICH FLY ASH,CONTEXTUAL ANAYSIS OF QUALITATIVE
ENVIRONMENTAL RISK ASSESSMENT AND FEASIBILITY STUDY ON
DISPOSAL TECHNOLOGY FOR POPs WASTE
1. BACKGROUND
The risks from the storage of obsolete pesticide products containing persistent organic pollutants
(POPs) are a major problem in China. The obsolete POPs pesticides are currently in dangerous
storage conditions such as outdoor storage and simple enclosure, leaking from rusted containers,
contaminating ground water and soils and poisoning human health and the environment. The
absence of adequate capacity and infrastructure for the Environmental Sound Management
(ESM)and disposal of the above POPs wastes in China poses significant risks and consequences to
human health and the environment. Current practices dominated by incineration without
consideration of the SC requirements under the national hazardous waste program for POPs waste
disposal are likely to generate secondary pollution such as dioxin and furan formation and release.
In addition, it is estimated that fly ash containing a high level of dioxin from incineration of
hazardous wastes and medical waste amounts to 11,000 tons per annum. According to the current
regulations, these solid wastes should be disposed to landfill following stabilization, or
irreversibly destructed and transformed into environmentally harmless substances. Limited by site,
technology and concept, solid waste incineration plants commonly adopt storage or simple landfill
disposal of hazardous thereby increasing the potential POPs pollution risk to water resources.
The project will enable Environmentally sound management (ESM) and disposal of accumulated
POPs pesticide wastes and other POPs related wastes in fulfilment of China’s commitment to the
national implementation of the Stockholm Convention (SC) and the National Strategy for
Hazardous Waste.
At present, the Ministry of Environmental Protection (MEP) and United Nations Industrial
Development Organization (UNIDO) are developing and formulating the project document. The
preparatory and development works include the following three aspects:

Investigation on current status of obsolete POPs pesticides and feasibility study of
special management for obsolete POPs pesticide based on the requirement of
environmental sound management;

Characterization of dioxins rich fly ash, application feasibility of Qualitative
Environmental Risk Assessement(QERA) and technologies feasibility study for POPs
waste disposal.

Feasibility study and proposal on Stakeholder and public-private partnerships on POPs
waste management
This Terms of Reference is proposed for the sub-contract focusing on quantification and
characteristic information of dioxins rich fly ash from a typical medical or hazardous waste
incineration plant, contextual analysis of QERA application to the project, technologies feasibility
study for POPs waste disposal.
2. GOAL
The goal of the sub-contract is aimed at carrying out multi-tasks investigation as follows: 1.define
nature and magnitude of dioxins rich fly ash; 2.contextual analysis of QERA application to the
project; 3.technologies feasibility study for POPs waste disposal
3. DUTIES AND CORRESPONDING ACTIVITIES
Activity 1
Activity 2
Activity 3
Activity 4
Activity 5
Investigate current status of management of dioxins rich ash generated in
incineration plants in China; Assess the current practice for dioxins rich ash
management; Propose the corresponding requirement for management and disposal
of such typical POPs waste as well as selection criteria of enterprise running
business of waste management and disposal.
Carry out the survey on the nature and magnitude of dioxins rich ash which are
generated in typical incinerator(stoke-furnace, fluidized bed, rotary kiln ) through
field investigation; characterize the physical-chemical features through sampling
and lab analysis, which shall be set as the context for the disposal technologies in
this project.
Contextual analysis of QERA application to the project, identify and assess the
contextual parameters potentially including the source waste, potential pathways,
vulnerable receptors, elements of geology and hydrology. The process will be
carried out by the field visits to a number of sites.
Investigate the technical and economical features of commercialized disposal
technologies for POPs waste in home and abroad, the focal points including:
technology applicability & reliability, pretreatment requirement, destruction
efficiency& destruction and removal efficiency (DE&DRE), disposal by-products,
disposal capacity, off gas treatment, resource need, cost-effectiveness (capital
investment estimation and operational cost). Propose a feasible technology study
for obsolete POPs pesticide disposal and dioxins rich ash based on the requirement
of the project, in which, Selection criteria for available disposal technologies for
obsolete POPs pesticide and fly ash should be specified, including plasma, rotary
kiln, stationary and mobile disposal facility .
Provide assistance to the drafter of Project Document(PD) during whole phase of
PD development and feedback to the comments and questions on the PD raised by
international organization
4. OUTPUTS
