Low carbon action – Chapter No.3

  1. Packaging and printing equipment, materials, printing and packaging manufacturers attach importance to energy saving and emission reduction 

Coincidentally, not only packaging design has taken the lead in energy conservation and environmental protection, but packaging materials, equipment, and enterprises have all paid attention to energy conservation and emission reduction.

At the end of 2009, Foshan Debao Printing Machinery overcame the industry problem of large-scale recycling of heat energy and solvent at the same time, and made major breakthroughs in energy-saving and emission-reduction technologies and applications. DePauw’s latest recovery device uses the latest generation of heat pump technology. By using the heat pump evaporator end to condense the hot exhaust gas discharged, the solvent is collected from a gaseous state to a liquid state. The treated, water content is lower and no water. The dust air is reheated by the radiator end of the heat pump and continues to be used for drying the product. In this way, almost 100% of the solvent is recovered, and the heat energy is also recycled. The energy consumption is less than 30% of the original, and it is truly zero. emission. This technology is of epoch-making significance. It will end the large consumption of solvents in the printing, laminating and coating industries, and save nearly 70% of the energy used for drying, saving a lot of money, not to mention the need to pay sewage charges. It can reduce the cost of electricity capacity increase or the purchase of boilers. Due to restrictions on the emission of organic solvents, many manufacturers have switched to water-soluble inks and glues, but compared with the organic solvent process, they have to pay a price in terms of product quality, production efficiency, material cost, and energy consumption. DePauw calculated an account for several nearby companies with an annual turnover of about 50 million: using DePauw’s recycling device, the annual savings can range from 5 million to 8 million, accounting for 50% of the turnover. 10%~15%.

Sinar Mas Paper (APP) completed the group’s first “carbon footprint” assessment project in early 2009, becoming the first enterprise in the domestic pulp and paper industry to conduct a large-scale carbon emission assessment, setting a clear benchmark for long-term energy conservation and carbon reduction management String. As of the third quarter of 2009, the total area of plantations managed by APP reached 4.98 million mu. With its outstanding contributions in energy conservation and emission reduction, environmental protection, etc., Sinar Mas Paper was awarded the title of “Low-Carbon China Contributing Enterprise (International)” at the first annual meeting of the “Low-Carbon China Forum”.

The carbon-free low-temperature cold-setting corrugated production line launched by Hong Kong Dongzhuo Technology does not require any heating equipment, and the corrugated paper is formed at room temperature, thereby achieving maximum energy saving. The production line does not need boilers, coal, steam, heating, no pollution, and no emissions, breaking through the previous state of using boilers to burn coal, low-temperature and low-carbon emissions. Next, it will strive to achieve a technological breakthrough with zero emissions and zero pollution.

Wan Jie, Chairman of Artron Enterprises (Group) Co., Ltd., expressed the need to pay attention to environmental protection: “The key word in the next era is environmental protection. In the past, most enterprises in Shenzhen used extensive operations, and in the future, the environmental protection indicators will be higher and higher. How can we achieve this? Environmental protection, how to save energy, Shenzhen enterprises will face great challenges in the next ten years in this regard.”
