Award [1] for each of three distinct points in an explanation of how the manufacture of the Treak Village plastic brick addresses the green design objectives of materials, energy and waste.
Mark as [3] + [3] + [3].
Materials:
The plastic brick uses plastic produced from waste ✓
This replaces the aggregate/stone that would otherwise be used
in the brick ✓
Reducing the quantity of raw materials used in the production
of the brick ✓
Energy:
The concrete for the plastic bricks is mixed/moulded by hand/locally ✓
This requires less energy than manufacturing bricks commercially ✓
Reducing energy used in production/transportation ✓
Waste:
The plastic brick reduces the amount of waste remaining/circulating
in the environment ✓
By recycling the plastic found locally ✓
So it is no longer visually polluting/causing contamination ✓
Award [1] for each of three distinct points in an explanation of why end- of-pipe technologies may not be the most effective strategy to reduce pollution of up to [3 max].
Answer in brackets is not required to award the mark
Do not award marks across clusters
end-of pipe technologies only focus on reducing pollutants at the
end of a process ✓
however pollutants may still be released during the production process ✓
strategies (system level solutions) that capture the pollutants earlier in the production process can result in less pollutants being emitted overall ✓
end-of pipe technologies only focus on reducing pollutants at the end of a process ✓
different types of pollutants can be released during the manufacturing process ✓
that may not be addressed/eliminated with one single solution ✓
Award [1] for each of three distinct points in an explanation of why products may be designed so that they cannot be easily disassembled up to [3 max].
Answer in brackets is not required to award the mark
Do not award marks across clusters
some products are designed with planned obsolescence (in mind) ✓
meaning products need to be replaced/consumers need to buy new products ✓
increasing sales/profits (for the company) ✓
some products are designed to prevent access to (internal) components/parts ✓
due to structural/mechanical/electrical/chemical risks ✓
to ensure safety/prevent possible injury ✓
consumers may attempt to repair/modify a product themselves ✓
using incorrect techniques/incompatible components ✓
which can impair the performance/function/quality of the product ✓
Award [1] for each of three distinct points in an explanation of why the smartwatch is an example of a converging technology up to [3 max].
converging technology is the merging of information/communication technologies ✓
the smartwatch combines the traditional wristwatch with modern digital applications/technologies ✓
in a single wearable device/reducing the need for multiple devices ✓
Award [1] for identifying how the IDEO trolley is an example of incremental green design strategy and [1] for a brief explanation.
small scale change / making minimal changes to the system ✓
that leads to a more efficient/environmentally product / leads to continuous improvement / reduces costs to improve the product / based on feedback from users ✓
Award [1] for each of three distinct points in an explanation of how the IDEO trolley uses waste mitigation strategies.
Mark as 3 + 3 + 3
Do not award marks across different clusters
reuse ✓
reuse of a product in the same context or in a different context ✓
the trolley can be reused by other people for water delivery / The trolley can be used for purposes other than delivering water ✓
recycle ✓
using materials from obsolete products to create other products ✓
once the trolley becomes obsolete the steel / wheels can be recycled for other products ✓
repair ✓
the reconstruction or renewal of any part of an existing structure or
device ✓
if the tyres get punctured they can be fixed / patched / inner tube
replaced ✓
if the wheels get damaged / worn they can be straightened / have new bearings fitted ✓
if the steel frame gets damaged it can be welded back together ✓
recondition ✓
rebuilding a product so it is in an “as new” condition ✓
the frame can be repainted to return to as new condition ✓
the wheels can have new bearings fitted so they run smoothly as new ✓
reengineer ✓
redesign components or products to improve their characteristics or performance ✓
the steel frame is easy / inexpensive to modify, so it can be reengineered to suit changing needs ✓
dematerialisation ✓
the reduction of total material and energy throughput of any product ✓
the steel frame is very basic, using the bare minimum of materials needed, reducing the energy required for materials and production ✓
the wheel configuration is simple, using only three wheels with no steering, this is the minimum required for the trolley to function ✓
Award [1] for identifying a reason why the Powerwall may be seen as an example of eco-design and [1] for a brief explanation.
Do not accept any answers in relation to cost or general terms such as environmentally/eco-friendly or green design.
uses solar energy ✓
which is a renewable / infinite resource / minimises energy derived from fossil fuels ✓
reduces the use of non-rechargeable batteries ✓
which lowers the impact on landfill / toxins in the environment ✓
adaptable / makes use of existing infrastructure ✓
as it connects to national grid ✓
Award [1] for identifying each difference between renewable and non-renewable energy up to [2].
renewable resources will not run out / can be replenished within a reasonable timeframe / are infinite ✓
non-renewable resources will run out / cannot be replenished as they do not re-form at a rate that makes its use sustainable / are finite ✓
Award [1] for identifying a reason why the efficiency of a lithium ion battery will not remain at 92% and [1] for a brief explanation.
the battery’s life will decrease over time ✓
due to degradation occurring through discharge / repeated charging
cycles ✓
the location of the battery in direct sunlight / exposed to high
temperatures ✓
may lead to increased rates of thermal degradation ✓
Award [1] for a correct definition of embodied energy
the total energy required to produce a product
Award [1] for listing each driver for employing clean technology in the production of the Dish Doctor.
Do not accept answers such as “reduce environmental impact” or “environmentally friendly”
promoting positive impact ✓
ensuring neutral impact ✓
minimising negative impacts through conserving natural resources ✓
reducing pollution and use of energy ✓
reducing wastage of energy and resources ✓
legislation ✓
incentives ✓
consumer/pressure groups/media ✓
