The meaning of green packaging and LCA technology

The so-called green packaging has not yet seen a complete definition. I believe that there are generally four aspects, namely: the least material, the least waste, and saving resources and energy; easy recycling and recycling; waste combustion produces new energy without secondary pollution; packaging materials and Decompose on your own without polluting the environment.

The packaging and the environment complement each other. On the one hand, the packaging needs to consume energy and resources in its production process. The generation of industrial waste and packaging waste will pollute the environment. It also needs to see that the packaging protects the goods and reduces the damage of the goods in circulation. It is conducive to reducing environmental pollution.

In resolving the relationship between packaging and the environment, we must not only consider how to deal with packaging waste, but consider that the packaging products needed by people in all activities are the cost of depleting natural resources and energy, generating waste, and affecting the global environment. . Therefore, the goal of packaging is to preserve the maximum natural resources, to form the minimum amount of waste and minimal environmental pollution.

In the 1970s, environmental experts proposed the LCA (Life Cycle Assessment) as the "ecological cycle assessment method."

LCA technology is attracting attention internationally. In Japan, the United States, Germany and other countries have used this analysis to assess packaging materials.

The selection of packaging materials from raw materials, material processing and manufacturing, and disposal or recycling of waste materials has a direct relationship with the environment. With LCA technology, these impacts can be quantified and corresponding improvement measures can be formulated.
