Resource Efficiency. The main resources consumed by current Beyti operations are electricity, water, fuels and the raw food materials, such as milk and plant extracts (e.g. juice) that are made into finished products. Those over which it has direct control as far as consumption are electricity, fuels and water. As such, the company has focused on using these inputs in the most efficient manner possible; and it continues to implement measures to further reduce their consumption of them, in particular, measures to reuse water, in keeping with the objectives of this Performance Standard.
For the existing operation, Beyti relies on three (3) main inputs; (i) grid electricity provided by the government (Beheira Electricity company) with an estimated consumption of 45,873,524 KWh annually (based on 2016 data), (ii) raw water with an estimated consumption of 1,121,565 (m3) in 2016, and (iii) diesel with an estimated consumption of 4,480,961 liters equivalent to 3,965 tons (also in 2016). The facility also operates four (4) diesel-fueled boilers (that are responsible for the bulk of the operations’ greenhouse gas emissions or GHG); three of the boilers have a capacity of 8 tons steam/hour and the fourth is 12 tons steam/hour. The emissions of these boilers range between 0-3ppm CO, 5%-11.55% CO2, and an overall efficiency ranging between 82% to 85%. Beyti is currently exploring options to save fixed electrical consumption by operating refrigeration pumps on variable frequency drive (VFD); this initiative will require an investment of EGP1 million and is currently under study.
For the existing and new operations, Beyti shall calculate the total CO2-equivalents based on its electricity and diesel consumption; amounts will be reported to IFC in the Annual Monitoring Report (AMR) along with reductions tied to initiatives such as the use of VFDs.
Air emissions monitoring. The main air pollutants from food and beverage processing operations are generally particulate matter (PM) and odor; these come primarily from the boilers. Beyti implements air emissions control and monitoring measures in accordance with applicable regulations and standards, and has reached a level of efficiency ranging between 88% and 98% for its boilers emissions.
For the new factory, the main source of air emissions is expected to be the burning of diesel from the three (3) boilers used in the production process. According to the EIA, the PM from air emissions are expected to be 6.9 mg/m3, whereby other emissions include CO (14 mg/m3), NO2 (98 mg/m3), CO2 (5.9%), with an estimated energy efficiency of 89.7%. The rates of air emissions are below the benchmarks stipulated by the Egyptian Environment Law (9/2009) and its executive regulations (710/2012) and those of the WBG/IFC General EHS Guidelines.
Water use and efficiency. Water use is mainly allocated for processing and production purposes especially for the juice operations, and is supplied by the public government network (via a surface canal) via the Holding Company for Drinking Water and Wastewater in Beheira Governorate. Several technologies and processes are used for raw water treatment including ultra-filtration, clarification, reverse osmosis, chlorination, carbon filtration and ultra violet light.
For the existing facility, water is mostly used for production process within the facility including juice production, milk production, and fermentation process resulting in a total of 318,522.06 tons of products being made. As noted above, in 2016 total water consumption over 12 months was estimated to be 1,121,564.14 m3 of water; therefore, average rates of consumption are 3.52 m3 per ton of production for all products. Out of the total 318,522 tons of production, 42.5% are juice products (135,527.92 tons), 45.77% are milk products (145,819.11 tons), and 11.73% are fermented products (37,174 tons).
For its existing operation, Beyti is engaging in water saving initiatives to further reduce this rate of consumption including (a) condensate recovery from 20% to 35%, (b) homogenizing cooling water recycling, and (c) reducing Cleaning-in-Place (CIP) final rinse time of yogurt and process equipment.
The new juice facility will include a raw water treatment facility with a capacity of 4,800 m3/day of water for the production of 1,872 tons juice/day. Average water use is expected to be 175 m3/hour and 4,200 m3/day or 600 m3 less than the total capacity of the raw water treatment facility. This use is divided as follows; 1,872 m3/day for industrial processes, 1,200 m3/day for CIP washing, 480 m3/day to supply the boilers, 600 m3/day for cooling process, and 48 m3/day for human consumption and floor cleaning purposes. The total of this water demand is 4,200 m3/day thereby giving an average consumption of 2.65 m3/ton juice produced, which is considerably lower than the 6.5 m3/ton figure referenced in the WBG EHS Guidelines for Food and Beverage Production.
Wastewater Treatment. For the existing operation, the plant utilizes a wastewater treatment plant with a daily capacity of 800 m3, originally constructed by Veolia. Beyti obtained a license to use Al Nasr agricultural drainage canal to release its treated wastewater and government authorities regularly take samples to check compliance with the limits contained with regulations. Industrial liquid waste is treated in a wastewater treatment plant then directed to the drainage canal; a portion of the treated wastewater is used to irrigate the landscape within the existing facility. (Beyti issues a monthly report indicating Effluent Treatment Plant Metrics for daily operations for PH, TDS, and COD (mg/L). The daily report includes volumes of raw wastewater, after DAF, and after SBR).
Nevertheless, while the factory has obtained the needed licenses and permits to currently use the agricultural drain, the EIA for the new facility indicates that the capacity of the existing water treatment unit (800 m3) is smaller than the actual volume of industrial water currently being generated. According to the EIA document, this limited capacity results in the company discharging some untreated wastewater in Al Nasr agricultural drain, which is not compliant with Egyptian Environmental laws and regulations (see law 48/1982 and law 82/2013 concerning pollution of surface drains.)
For this reason, Beyti decided to establish a new treatment facility as part of the construction of the new factory with a capacity of 3,200 m3. It is expected the treated wastewater in the new treatment facility shall total 2,972 m3 which is comprised of 1,388 m3 from the existing operations (as a corrective action to address the excess volume of wastewater being released untreated directly into al Nasr drain), in addition to 1,584 m3 of wastewater expected to be generated from the new juice operation. The 1,584 m3 of wastewater generated from the new operations is divided as follows; 1,392 m3 industrial wastewater, 24 m3/day from boilers, 120 m3/day from cooling towers, and 48 m3/day for sanitation purposes.
Based on the total capacity of the new treatment facility (3,200 m3/day), an amount of 1,200 m3 will be reused for landscape and watering trees within the facility, while 2,000 m3 of water will be released into the Nasr drain in line with the new Egyptian code for wastewater treatment number 501/2015. The company will report on compliance of wastewater release in agricultural drains from both existing and new facilities to IFC once the new treatment facility is up and running. This is ESAP action item # 4.
The IFC E&S team has proposed to the company to avoid co-mingling of the sanitary wastes with the process wastes in the new 3,200 m3/day ETP. The company is encouraged to explore the opportunity to treat and re-use some of the process water by restricting the use of the existing 800 plant for sanitary wastes (given that the facility does not include a large number of workers), and keep the 3,200 plant solely for process water. Beyti indicated that this option is under consideration at present with the local environmental consultant. A study is being undertaken to review the collection of waste water volumes and the piping network distribution, and their related impact on drained treated water KPI’s.
Management of solid and hazardous wastes. There are three (3) categories of waste generated by Beyti facility including; (i) solid waste, (ii) liquid waste (already described above), and (iii) hazardous waste. Solid waste constitutes around 75% of total generated waste by Beyti’s existing facility, and includes paper (2%), plastics (1%), cardboard (50.9%), steel metal (20.6%), sludge (16.4%), combi (1.9%), foil (0.1%), glass bottles (0.03%), and paper towels (0.2%). The factory separates waste at the source. Solid waste is sold by ton as scrap to contractors for recycling. Solid waste that cannot be sold is transported and handled by governmental authorities who are contracted on an annual basis to dispose waste. Non-recycled waste is disposed in public landfills in the city of Abou El Matamir.
Other liquid wastes include chemical substances and oil used in the repair and maintenance of the production equipment which is classified as flammable liquids. Hazardous waste mainly include chemicals used in the industrial process. All hazardous chemicals are stored in clearly marked lockable stores and their incoming/outgoing movements are documented in the department log book. These wastes are stored in barrels and are purchased by a petroleum company.
For the new plant, it is estimated that the amount of generated solid wastes will be as follows; cardboard (287.5 tons/year); plastic waste (893 tons/year), wood (1 ton/year), rolls (55 tons/year), sugar bags (60 kg/year), plastic (70 tons/year), solid waste from wastewater treatment process (1.8 m3/day equivalent to 648 m3/year), human waste (3,960 m3/year). In terms of hazardous waste for the new plant, it is estimated that chemical containers (99 tons/year).
