Engineering Biology Mission Hub
Exploring biological approaches to plastic pollution and the controlled deconstruction of synthetic polymers.

Waste is a design problem.
Plastic Waste Hub presents complex evidence in a clear, accessible way, helping readers explore better products, informed choices and circular material systems.
Understand the whole journey
Design beyond disposal.
We examine how materials are selected, used, collected and recovered—because no single intervention solves the system.
Evidence made useful
From research to action.
Concise project summaries connect material science, engineering, policy and everyday behaviour.
About this site
A practical view of plastic.
Look at the full system
Useful decisions account for product purpose, material chemistry, manufacturing, user behaviour, local collection and realistic end-of-use routes. The site organises those connected questions into accessible project and news summaries.

shared system linking design, use, collection, sorting and recovery.
Changing one stage can affect every other stage.Selected projects
Ideas tested in context.
These project records cover biological processes, compostable materials, product systems and design interventions.
The Big Compost Experiment
A completed citizen-science study investigating how products labelled compostable performed in home composting.
The Comfort Loop
A systems approach to more sustainable absorbent hygiene products, from material selection to collection and treatment.
Designing-Out Plastic Waste
Research into design choices that can prevent avoidable waste before products reach the market.
Compostable plastics and systems change
Examining where compostable formats may be appropriate and what infrastructure, identification and guidance they require.
How we work
Follow the material, not the assumption.
Each topic is considered through a consistent four-step editorial framework.
Frame the need
Start with the function a product performs and the people or organisations involved.
Map the system
Trace materials through manufacture, use, collection, sorting and treatment.
Compare options
Consider trade-offs and avoid treating a material label as a complete answer.
Share clearly
Translate technical findings into concise, usable summaries with appropriate limits.

Common questions
Plastic is not one thing.
Does a resin code mean an item is recyclable?
No. The code identifies the broad material family. Collection rules, colour, format, contamination and local processing capacity also affect whether an item can be recycled.
Are compostable plastics suitable for every use?
No. They can be useful in specific systems, but require clear identification, suitable collection and compatible treatment. They should not be assumed to break down in every natural setting.
Why not replace every plastic item with paper?
Material substitutions can shift impacts rather than remove them. Product weight, durability, barrier performance, transport, reuse and disposal all need consideration.
What belongs in a whole-system assessment?
Raw materials, manufacturing, function, user behaviour, collection, sorting, recovery and leakage risk should all be considered, along with credible alternatives.
What is included on Plastic Waste Hub?
