Refillable Jug System Reduces Plastic Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread use of plastic jugs for liquid laundry detergents results in significant plastic waste and recurring costs for consumers, as they need to purchase new jugs frequently, contributing to environmental issues and inefficiencies in energy and landfill usage.
Innovation Solution
A refillable jug system is introduced, where a new empty jug is sold with a small, concentrated pouch of water-soluble laundry detergent premix, allowing consumers to mix a multi-serving quantity of detergent at home, and separate refill pouches are available for subsequent purchases, reducing plastic waste and the need for frequent jug purchases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If consumers purchase new plastic jugs for each laundry detergent purchase, then they have access to fresh detergent, but plastic waste increases and consumer costs increase
Solution Approach 1:
The system divides the detergent product into two separate components: a durable refillable jug (container) and disposable detergent refill pouches (contents). This segmentation allows the container to be reused multiple times while only the detergent contents are discarded, directly reducing plastic waste from the container portion while maintaining convenience through easy refill acquisition
Solution Approach 2:
The system implements a recovery loop where the jug is retained and reused across multiple purchase cycles. Instead of discarding the entire jug after one use, consumers return or retain the jug and purchase separate refill pouches, thereby recovering and reusing the container portion repeatedly while only discarding the depleted detergent contents
2Loss of substance
If consumers purchase new plastic jugs for each laundry detergent purchase, then they have access to fresh detergent, but recurring costs increase
Solution Approach 1:
By separating the jug from the detergent contents, the system allows consumers to make a single investment in the durable jug and then purchase only the essential detergent portion in subsequent refills, reducing the recurring cost burden by eliminating the need to repeatedly purchase expensive new containers
Solution Approach 2:
The recovery model enables consumers to retain the value of the jug across multiple purchase cycles. The initial jug purchase pays for itself over time through multiple refills, effectively reducing the per-use cost and total expenditure compared to purchasing complete jug-and-detergent units repeatedly
3Loss of energy
If a small concentrated pouch of detergent premix is used to fill a large jug, then plastic waste is reduced and shipping costs are minimized, but the mixing process requires consumer action
Solution Approach 1:
The system changes the concentration parameter of the detergent product by providing it in a highly concentrated premix form in the refill pouches. This concentration allows the same amount of active detergent to occupy much less volume, reducing shipping energy and costs while still providing sufficient quantity to fill the large jug when mixed with water
Solution Approach 2:
The system transfers the mixing function to the consumer at home, where they simply combine the concentrated premix with water in the jug. This self-service approach eliminates the need for the manufacturer to perform energy-intensive dilution and shipping of ready-mixed detergent, while the consumer performs a simple mixing action that requires minimal effort
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system significantly reduces plastic waste, lowers consumer costs, and promotes sustainability by allowing the reuse of the refillable jug, potentially for the lifetime of the product, while minimizing shipping energy and costs.
Implementation Method 1
a small first packet or pouch of water soluble laundry agent premix in dry or liquid concentrate form

AI summary
A system and method for supplying liquid laundry detergent refills to a consumer. A new empty refillable original laundry jug or container made of plastic or similar is sold with a small, lightweight first-use pouch of water-soluble laundry detergent pre-mix as a unit at a retail point of purchase. A separate supply of refill pouches of the pre-mix powder are available for purchase at any time after or separately from the original purchase of the original new empty jug. A consumer only needs to purchase the new empty refillable jug (with its included first-use pouch) once; subsequent refill pouches are purchased without a jug, and used to make an unlimited number of liquid refills in the originally purchased jug.
