Short answer

When selecting materials for a design project, consider not only their performance and cost but also the potential environmental hazards associated with their disposal, especially if incineration is a likely end-of-life pathway.

Field: Resource Management
Source: Journal of Toxicology and Risk Assessment (2019)
Method: Literature Review
Evidence: Strong effect

Incinerating plastic waste, a common disposal method, releases hazardous chemical constituents into the environment, posing risks to ecosystems and human health. This resource management research insight is drawn from a 2019 study published in Journal of Toxicology and Risk Assessment. Using Literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When selecting materials for a design project, consider not only their performance and cost but also the potential environmental hazards associated with their disposal, especially if incineration is a likely end-of-life pathway.

Key Findings

01A significant amount of plastic produced globally is not recycled or incinerated.
02Plastics contain toxic chemicals such as phthalates, heavy metals, and flame retardants.
03Incineration of plastic waste releases these toxic chemicals, contaminating air, water, and soil.
04These contaminants negatively affect organisms and human health.

Application

Design takeaway

How to apply

When evaluating material options, research the chemical composition of the plastics and the potential emissions from their incineration. Seek materials that are less toxic or have established, safer disposal routes.

Project actions

01When choosing materials, think about what happens to them after you're done using them.
02Research the chemicals in your chosen materials and how they might affect the environment if burned.

Method & Evidence

AimWhat are the environmental and public health effects of various plastic waste disposal methods, particularly incineration?

MethodLiterature Review

ProcedureThe researchers reviewed existing academic papers to synthesize information on plastic production, chemical constituents, disposal methods, and their associated environmental and health impacts.

ContextEnvironmental Science, Public Health, Waste Management

Variables

IVPlastic waste disposal method (e.g., incineration)

DVEnvironmental contamination (air, water, soil), human health impacts

CVType of plastic, specific chemical constituents, incineration technology, local environmental conditions

Strengths & Limitations

Strengths

+Provides a comprehensive overview of the issue by synthesizing multiple studies.
+Highlights the broad range of toxic chemicals present in plastics.

Limitations

The specific toxic chemicals released and their concentrations can vary significantly based on the type of plastic and the efficiency of the incineration process.

Reliability & validity

The reliability and validity of the findings depend on the quality and scope of the reviewed literature. A meta-analysis would provide stronger quantitative conclusions.

Think critically

How can designers mitigate the risks associated with plastic waste incineration through material selection and product design, even when incineration is the mandated disposal method?

Design Principles

"Design for Environmental Responsibility: Account for the full lifecycle impact of materials and products, including their disposal, to minimize harm to ecosystems and human health."

Designers and engineers must consider the full lifecycle impact of materials. Understanding the environmental consequences of disposal methods like incineration is crucial for developing more sustainable product designs and material choices.

What This Means for Your Design

Burning plastic can release bad chemicals into the air, water, and ground, which is bad for nature and people.
