Environmental Performance Evaluation
From the perspective of basic materials, wood-plastic composite materials make full use of waste plant residues such as wood chips, bamboo chips, rice husks, and peanut shells;Moreover, the plastic-wood composite material does not contain substances harmful to the human body, and the waste plastic-wood composite material can be recycled without causing damage to the environment. The raw material composition and ratio relationship of plastic-wood composite materials, waste plastics and plant fiber residues are the main raw materials of plastic-wood materials.
Relevant data show that every 1 ton of plastic-wood composite materials used can reduce the harvesting of tree resources by 5 cubic meters, which is equivalent to reducing nearly 1.8 tons of greenhouse gas emissions and increasing the release of 1.6 tons of oxygen. .Based on the waste plastic composition of 30% composition, every 1 ton of wood-plastic composite materials produced can reduce nearly 0.3 tons of environmental pollutants, which can greatly reduce the load on the environment. By replacing natural wood with plastic-wood composite materials, forest resources are saved and the natural environment is protected.
Environmental Coordination Evaluation
Due to its decorative properties, wood-plastic composite materials show good coordination with the surrounding environment.
(1) Wood-plastic composite materials come in various colors. According to the needs of customers, the color of the material can be changed by adding toner during the preparation of wood-plastic composite materials. The light-colored wood-plastic composite material gives people a relaxed and pleasant visual and psychological experience, while the original color close to natural wood can satisfy people's sensory requirements for being close to nature.
(2) The gloss and pattern decoration of wood-plastic composite materials are rich. The gloss and patterns of wood-plastic composite materials can be customized and suppressed according to customer needs. The patterns of wood-plastic composite materials can be almost fake, and combined with the gloss and shade of the material, it can give people a different feeling.
Environmental Load Rate Evaluation
The environmental load rate is often used to evaluate the impact of a certain material product on the surrounding environment. The greater the value of the environmental load rate, the greater the impact of the material product on the surrounding environment. Therefore, the lower the environmental load rate value, the better the ecological performance of the material product. In order to better explore the impact of wood-plastic composites on the environment, the environmental load rates of wood-plastic composites, foam concrete, and ordinary concrete were compared. It is concluded that compared with foam concrete and ordinary concrete, wood-plastic composite materials have obvious advantages in the degree of environmental impact, that is, wood-plastic composite materials have better ecology.
