Pollution Abatement:
Limited air emissions arise from the company’s logistics centers stemming from the occasional use of diesel backup power generators, and from limited quantities of LPG used in cafeteria kitchens as cooking fuel. Most of these centers are powered by grid electricity, and steam supplied by municipal steam companies for indoor heating. Some centers have natural-gas-based boilers for facility heating purposes, and given the use of natural gas as fuel, resulting air emissions are low in Sulphur content. Where boilers are in use, there are appropriate air emission treatment measures and monitoring regimes in place meeting national and local regulatory requirements on energy related air emissions.
The company’s logistics operations utilize limited amounts of water mainly for staff and sanitary purposes, with water supplied by municipal or industrial park water provision companies. Waste water (WW) is limited to sanitary wastewater and effluent generated from staff canteens, dormitories, or other staff and operational/storage areas, and is discharged to the local municipal sewers for treatment. Solid wastes at product distribution centers mainly consist of paper cartons and packaging materials. Most of these are reused for product packaging, or in some cases returned to suppliers, as the company has a policy of minimizing solid waste generation and maximizing re-use.
At the Beijing and Shandong manufacturing plants, WW generated is treated by on-site waste water treatment plants (WWTP), by a process comprising Fenton oxidation, sedimentation, anaerobic biological treatment, and aerobic treatment, before being discharged to the municipal/township WWTP for further treatment. Monitoring is achieved in four ways: (i) company technical staff sample WW for testing on-site; (i) the local environmental protection department (EPD) conducts unannounced spot-checks by taking waste water samples and inspecting internal monitoring results retained by the company; (ii) annual sampling and monitoring is conducted by a third party licensed technical institute; and (iii) the on-site WWTP is connected to the local environmental authority through real-time monitoring equipment enabling monitoring by the authorities at all times of a number of discharge parameters. Post-treatment WW monitoring results by a third party technical monitoring institute (dated October and December 2018 with samples collected at the point of discharge from the on-site WWTP) indicated the following: (i) Beijing plant (TSS, COD, BOD5): materially compliant with national and World Bank Group (WBG) Environmental Health and Safety (Pharmaceuticals and Biotechnology Manufacturing) Guideline limits; (ii) Shandong plant (phosphorous and ammonia): materially compliant with national and WBG EHS guideline limits.
Process and energy related air emissions at the two manufacturing plants are treated using a combination of methods mainly comprising SNCR de-nitrification, FRP bio-towers (at the on-site WTP), bagged and electrostatic de-dusters, double alkali desulfurization, secondary activated carbon adsorption (for odor treatment at the WWTP). WW monitoring results by third party technical institutes indicated the following results: (i) Beijing plant (non-methane total hydrocarbon, hydrogen sulfide, methanol, particulate matter, ammonia, odor (density), and sulfuric acid mist): compliant with national/WBG EHS guideline limits; (ii) Shandong plant (NOX and odor density): compliant with national and WBG EHS standards.
Hazardous wastes:
The company reported that across its facilities in China, very small quantities of medical products were discarded in 2018 – where discards occurred these were collected and disposed of by the China Food and Drug Administration local offices, strictly as per national regulatory requirements. Sludge generated at the two manufacturing facilities are not classified as hazardous by the local authorities and are either landfilled or sold to brick making or road construction companies. At manufacturing facilities, the company has detailed procedures in place, as shared with IFC, governing the procurement, storage, handling, management, and disposal of ingredients and wastes classified as medical or hazardous. This includes access-controlled, and where required, explosion-proof and concrete lined storage areas for hazardous materials, which are located at a minimum required distance from production and other buildings. IFC’s visit confirmed that hazardous material usage and storage areas clearly displayed material safety data sheets, and handling procedures and emergency preparedness and response information were also clearly indicated in those areas for staff to see and follow.
Resource Efficiency and Greenhouse Gas Emissions (GHG):
Primary energy requirements for the project consist of: electricity procured from the grid, diesel oil used as fuel for the company’s truck fleet, and natural gas used as fuel in boilers at certain product distribution centers. The company’s 125 provincial and prefectural level distribution centers operate standalone commercial cooling units, medium to large sized commercial refrigeration units, transport refrigeration, and chillers, to ensure products are kept at the necessary optimal temperatures while in storage and transit. Some of the units currently utilize R22 as a refrigerant – the company will ensure that all new facilities constructed in future do not utilize R22 or other phased out refrigerants, and for existing facilities, will explore technically and financially feasible ways to switch from R22 to another refrigerant with a much lower global warming potential (GWP) e.g. HFC134a or R401A. Refer to the ESAP.
Based on these numbers and other data from the company for the year 2018, the total annual GHG emission of the company’s facilities under this project is estimated at about 90,000 tons CO2 equivalent, attributable mainly to: (Scope 1) fuel consumption; the use of refrigerants in operating commercial and industrial cooling units and equipment on site; and (Scope 2) grid electricity consumption. Given that this exceeds the 25,000 CO2te threshold as defined in IFC PS3, the company will use an internationally recognized methodology to annually estimate and report its total GHG emission footprint to IFC – to be included in the annual monitoring report submitted to IFC.
Each facility tracks its electricity and fuel usage and looks for opportunities to achieve reduction. For instance, the company’s product distribution center in Wuhan has invested in a solar rooftop power generation project, and a rainwater harvesting project, which has achieved notable savings since their commencement in 2015. In terms of transport fleet fuel efficiency, the company achieves this mainly through transport route optimization, timely vehicle maintenance to ensure that vehicles are in optimal running conditions, and close monitoring of each vehicle’s fuel consumption quantities.
