About Hanvo — Sustainability

Through the installation of solar energy systems on the roofs of our facility, we have been able to save approximately 1,214038 kWh/year of clean and renewable energy, which is equal to approximately 365.5 tonnes/year of CO2. A total of 20% of the facility’s energy is generated by solar power.

Challenge:  Become more energy efficient and reduce energy consumption

Solution: Install rooftop solar photovoltaic panels that can generate clean and renewable energy

Impact: Able to save 1.2 million kW of energy, reducing close to 365.5 tonnes of CO2 emission a year. The facility reuses 20% of the solar power generated.

Manufacturing gloves can produce exhaust gases and vapors which may be harmful to the environment if it is not treated with care. To combat this, we have an exhaust gas recovery and recycling system that is used throughout the glove production process. 

All exhaust gases are collected and treated through the use of RTO combustion, water spray, and catalytic oxidation before being discharged. As a by-product of the RTO combustion process, close to 14,850 tonnes of steam energy is created annually which is then reused for our glove production process. 

Challenge:  Treat exhaust gas from glove production

Solution: Equip the manufacturing facility with an exhaust gas recovery and recycling system. 

Impact: Over 90% of waste gases are collected and purified before being discharged. As a by-product of this purification,14,850 tonnes of steam energy are produced annually and reused for our glove production process. This also reduces CO2 emissions by 3419.9 tonnes per year resulting in a reduction of 15.8 grams of CO2 per pair of gloves. 

Manufacturing gloves can be a water-intensive industry. As a result, our plant is equipped with a sewage treatment system that treats industrial waste water before it is discharged.

The 24-hour intelligent, self-monitoring system is able to treat more than 350,000 tonnes of waste water per year which results in an effluent water quality of about 50ppm COD (national standard: COD300ppm). The treated water is then sent to a secondary waste water treatment company to be further treated before being discharged into the river or reused for domestic purposes.

Challenge: Manufacturing gloves can be a water intensive industry.

Solution: Equip the manufacturing facility with sewage treatment system that treats waste water before it is discharged; Engage with secondary waste water treatment to further treat it

Impact: Treated water is safe to be discharged into rivers (according to state laws and regulations) and can be reused for domestic purposes. It also reduces CO2 emissions by 41.7 tons/year equivalent to 0.19 grams per pair of gloves.

Our investment in R&D and proprietary technologies includes finding a solution to reduce plastic waste. As such, we developed the Ecotech™ range, a line of eco-friendly industrial gloves, made from recycled PET plastic bottles. The plastic bottles are turned into polyester yarns which are then knitted into gloves.

Challenge: Create sustainable products by reducing plastic waste

Solution: Develop gloves with proprietary technology that uses recycled PET plastic bottles turned into polyester yarns and knitted into gloves.

Impact: Able to reduce plastic waste by turning it into practical and functional products and reduce CO2 emissions by approximately 281.8 grams per pair of gloves.

We adhere strictly to ISO 14001 and ISO 45001 throughout our production process. To ease adherence, we have developed an all round ES system, that monitors production systems and is capable of responding immediately to production accidents.

Challenge: Improve environmental safety and management as well as efficiency of production and operations

Solution: Digitize systems to create an all-round monitoring system and a safety and environmental protection control center

Impact: Digitization has increased the efficiency of operations and productions, improved environmental and safety management, and reduced energy consumption at the production level. All these results have contributed greatly to becoming a carbon-neutral facility.

Packaging is an important component of our products’ life cycle. To reduce the product packaging’s environmental impact, we have chosen to use FSC certified cardboard and biodegradable sample bags. By making this conscious switch, we have managed to reduce CO2 emissions of by at least 281.8 gram on average, per pair of gloves.

Challenge: reduce product’s packaging environmental impact

Solution: Use FSC certified cardboard and biodegradable sample bags

Impact: Reduce CO2 emissions down to an average of 281.8 grams per pair of gloves.
