Full polymer catering trolley
Together with the AeroCat alliance – Promolding innovated the aluminum airline catering trolley to an EASA and ETSO certified full polymer trolley. The TIGRIS trolley distinct from any other competitive product in the market. The TIGRIS trolley provides a substantial con- tribution to a greener, healthier and safer airline environment as a whole and airline catering logistics more in specific. A casters alignment system is an option.
Passangers or operator benefits:
The TIGRIS trolley will enable to change the airline catering logistics substantially. The trolley will introduce new polymer applications to the industry, thus being able to optimize existing catering operations and shaping the industry for future innovative solutions. More specific, airlines will realize a high return on their investment by substantial fuel reductions, less maintenance costs, an attractive residual value of their investment, lower spending to cool food and beverages. longer lifetime and the possibility for future trading of emission rights (2012, ETS law), due to the low carbon ]]]footprint. Furthermore substantial savings can be realized by the related effect – using RFID technology – on the overall catering logistics. Additional value will be realized by attendant’s increased satisfaction on the several improved ergonomic aspects of the trolley and its aesthetics. Overall the airline has an attractive opportunity to contribute to a better world and thus creating an improved environmental friendly image for the airline industry.
Reducing negative effects in the environment
The trolley is from origin eco-designed for closed loop recycling, with the lowest carbon footprint in its kind (reference: Life Cycle Assessment of TNO).
Compared to aluminum trolleys, TIGRIS trolleys reduce the carbon footprint by a factor 2.2, not taking into consideration the differences in the use phase as a result of lower weight. The main difference comes from the differences in material production and the CO2 bonus for the recycling.
If saved CO2 emissions could be traded, with a CO2 price of €20 per ton, each FS TIGRIS trolley saves €41 of CO2 per year and each HS trolley €21 per year.
REDUCING THE TOTAL COST OF OWNERSHIP OF OPERATORS
The TIGRIS trolley will lower the Total Cost of Ownership substantially.
In most of the scenarios the IRR calculation shows attractive returns with already 100% return on the investment in the first year.
THE SPECIFIC BENEFITS OF THE TIGRIS TROLLEY
Fully sealed and will prevent putting unwanted items between the walls of the trolley, thus improving the overall safety on board;
The predicted lifetime is at least 10 years, by normal wear & tear;
The trolley body is developed with a ‘No Maintenance’ philosophy in mind;
A modern and appealing look, that will]contribute to overall passenger satisfaction;
No hidden corners and edges,]therefore easier to clean.
Better insulation than aluminum, due to its full polymer body with static air chambers. This will cause less use of dry ice, thus contributing positively to a lower carbon footprint;
High impact resistance. This will cause less damage to the trolley during the catering process and a longer attractive look;
Several ergonomic improvements. With these aspects, the airline improves automatically its health- and safety care for personnel, resulting in an overall improved satisfaction of the crew;
Visibility of scratches will be minimal by through and through colored polymer, thus maintaining a good look & feel. The overall image of the airline will be better sustained;
Standard equipped with 4 modern passive RFID tags, approved for airline use, resulting in optimized logistics processes.
THE TECHNOLOGICAL BREAKTHROUGH
A breakthrough design was needed. The objective was to develop a full polymer eco-designed trolley at low cost. The TIGRIS solution is a patented construction that facilitates a low cost- high volume production process in such a way that only virgin polymer material is used, providing a closed loop same level re-use. Furthermore, the full polymer characteristic provides the best situa- tion possible for use of RFID tags.
To develop an environmental friendly trolley, Promolding has chosen to produce its trolley from material that could be closed loop re-used, that would fit mechanical properties, that would be tough enough for misuse and that could face harsh chemical situations (washing street). The choice was made for the PPSU polymer (RADEL R) of Solvay.
The trolley body, a part of the door and the top tray are produced by extrusion. The production is on ‘infinite’ length and subsequently sawed to size. The extrusion made body is of such a dimension and difficulty that it’s unique within the polymer manufacturing industry.
The door is made in a combination of injection molding parts and an ‘inner wall’ extrusion part. Promolding succeeded in developing a door of full polymer by using its unique and patented design on the closing mechanism along the long side of the door panel. Along both long sides of the door, the hinge and the patented door locking mechanism keep the door in place at requested loads for certification
The TIGRIS trolley is developed for fast, high volume, robotized manufacturing thus keeping production costs at attractive levels and preventing low cost labor.
