Nowadays, the printing industry often hears well-known buzzwords, such as sustainable development, energy saving, carbon footprint and carbon neutralization printing. However, where should the sustainable development of printing enterprises start? What measures are practical and feasible for printing enterprises? Let's take a look at what lessons German Indian companies can offer us.
Managing Energy Efficiency
According to the survey data of energy efficiency consultant Jurrgen Burhler, printing enterprises with a scale of 3-250 people have an average energy-saving potential of 25% in terms of kilowatt-hour. The energy-saving potential of printing enterprises with 8 or more B3 printing units can reach 29%-45%, because these enterprises can save a lot in heating costs. Enterprises using thermosetting reel paper printing and thermal reburning equipment can also achieve completely different energy-saving efficiency through new technologies. Energy efficiency management not only brings low-cost products to enterprises, but also shows the potential of energy saving. Energy saving means that enterprises have competitive advantages.
In addition, it must be mentioned that compared with other industries, the energy consumption of the printing industry is not serious, only the roller printing enterprises with drying devices and the enterprises with thermal reburning equipment belong to the energy-intensive enterprise category. It firmly believes that the printing industry will make an important contribution in reducing energy consumption in the next few years.
Selection of environmentally friendly solvents
Printing enterprises have many choices in practical measures concerning environmental protection and cost reduction. For example, many printing companies are still using harmful and environmentally friendly solvents. This makes the printing industry one of the industries with VOCs emissions ** because it emits a large amount of organic volatile compounds (VOCs) every year, according to JU rgen Bu hler.
In addition to the use of environmentally friendly solvents, the use of measures to reduce solvent consumption and recycle organic waste gas instead of direct emissions or combustion and the resulting energy saving is worth doing by enterprises, which can protect resources.
Use environmentally friendly inks
Printing inks are gradually developing towards environmentally friendly inks, such as vegetable inks made from rapeseed, flax or soybean. This kind of ink does not need solvent recovery equipment in the use process, which reduces the generation of waste and protects resources, so it is sustainable compared with traditional ink. Printing enterprises should avoid using ink containing heavy metals, which is not only beneficial to the environment, but also to the physical and mental health of employees.
Recycling and reuse
In many enterprises, waste management and collection has become a daily activity. However, according to Jurrgen Burhler, the registration and recycling of waste remains an underestimated task. Therefore, some printing enterprises should formulate relevant programs to recover the inevitable and necessary waste, which can not only greatly reduce the environmental burden, but also save the cost of transportation and treatment of waste.
Do well the internal and external logistics management of enterprises
Internal logistics, especially production logistics, refers to a series of flows of printing raw materials, such as paper (or other prints), ink, printing plate, and finished products, semi-finished products, waste products, etc. in the process of printing production. Printing enterprises should improve process steps through * short transportation distance and process optimization, and pay attention to regular maintenance of transport vehicles, such as forklift trucks, otherwise it will consume more energy and cause unnecessary costs.
External logistics can be understood as the purchase and transportation of raw materials, the distribution and transportation of finished products, and the disposal of waste. Printing enterprises should carefully select raw material suppliers and waste disposal enterprises to reduce external logistics links or shorten logistics routes. In order to avoid empty driving, enterprises can also use GPS-assisted driving routes and carry out effective speed management.
