Designing a shared information system that connects fragmented waste-disposal rules across regions and countries, and translates them into a coherent product experience.
Date: 2026
Role: Sole product designer and developer
Primary context: Hong Kong, with comparative research across selected jurisdictions
Status: V1 built and validated
Challenge
Waste guidance is commonly organised around materials, collection programmes or authorities. Users, however, begin with a specific item and need a clear answer that applies to their location.
Approach
Wastend uses a structured rule model to connect items with local classifications, preparation requirements, exceptions and source evidence, then turns that structure into an item-first mobile experience.
Current State
The information architecture, interface and core user flows are complete and launch-ready. Current work focuses on validating, expanding and integrating the source-backed local rule database across supported jurisdictions.
Experience
WHAT USERS GET
From uncertainty to action.
Instead of asking users to interpret policy documents, Wastend presents the local classification, preparation steps, exclusions and source references relevant to the selected item and region.
Guide Tab
Search for everyday items or browse local waste categories to find region-specific disposal guidance.
Compare Tab
Compare how the same item is classified and handled across different regions, including local category and preparation differences.
Saved Tab
Keep frequently checked guidance in one place, with clear disposal instructions and the relevant region context.
Problem
WHY THE PROBLEM EXISTS
Same items, different rules.
Local disposal information is distributed across municipal websites, PDFs, collection schemes and facility pages. More importantly, these rules are jurisdiction-specific: a classification, preparation requirement or disposal route that is correct in one place cannot be assumed to apply elsewhere. People begin with the item they are holding, not the administrative system behind it, creating a need for source-backed guidance that preserves local differences while making the next step easier to understand.
System
HOW WASTEND WORKS
From scattered sources to structured guidance.
Wastend brings source-backed rules into a consistent structure of items, local classifications, applicable locations, preparation requirements and exceptions. This supports clearer user-facing guidance without erasing jurisdiction-specific terminology.
Architecture & Flow
HOW THE EXPERIENCE IS ORGANISED
Organising the product around the disposal decision.
Wastend uses a shared item-guidance structure across Guide, Compare and Saved. Global controls establish the regional context, while local classifications, conditions and source evidence remain jurisdiction-specific.

System challenge
Local guidance varies by jurisdiction, source, material and disposal route. The system therefore needed to remain coherent as new rules and regions were added.

Visual System
VISUAL SYSTEM
A flexible identity for a rule-heavy product.
Irregular forms reflected variation across local rules, while neutral surfaces, clear hierarchy and category labels kept dense guidance readable. Colour supported recognition, but was not intended to carry meaning on its own.
Outcome
OUTCOME
One system, carried from source evidence to working guidance.
The same underlying model preserved regional rule differences, completed the path from source acquisition to app-ready exports, and powered Guide, Compare and Saved with real data.
