Description:

Hydroflight is a watersport where the user utilizes a waterjet-propelled backpack to fly over water. These backpacks are usually powered by purpose-built equipment but can also be propelled by personal watercraft. To have full control over movement during hydroflight, the user needs to adjust the throttle of the watercraft, which is commonly performed by converting the system to remote-controlled operation. However, care should be taken during conversion to ensure safe operation and avoid harm to the user. This paper presents a failure analysis of sudden safety mode activation on a personal watercraft converted to remote control for hydroflight applications, as well as actions taken to avoid full shutdown in the case of communication loss, without compromising user safety.

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2023-01-01

Volume: 51

Issue: 3

Page Range: 270-274

Description:

It is difficult to determine the ideal way for collecting selective waste since calculations must be made taking into account a variety of collection vehicles, containers, city regions, and verifying vehicles. Additionally, we need to keep in mind that acquiring some statistical information on container filling is crucial for organizing the gathering process. The majority of the vehicles used for the gathering operate on fossil fuels like gasoline, which releases carcinogens into the atmosphere. Since the engine drives a hydraulic pump that generates power to lift the container when it is being emptied, the exhaust emissions are not solely coming from the vehicles when they reach the container. As a result, it is crucial to describe the entire gathering process. On the one hand, we want to safeguard the environment by utilizing selective gathering, but on the other hand, there are gathering vehicles that emit carcinogenic exhaust gas. In order to reduce unneeded pollution from the gathering vehicle, we aim to identify the best solution in this paper for choosing the appropriate selective material collection method.

Maximizing the Capacity Utilization of Selective Waste Collection Vehicles

István Lakatos Ádám Titrik

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2022-01-01

Volume: 19

Issue: 7

Page Range: 165-176

Description:

Selective Waste Collection is an essential part of recycling raw materials, in order to protect our environment. The waste collection is carried out by using a seriously polluting vehicle, due to the fact that most of the gathering vehicles are using fossil energy sources, like gasoline. High volume of carcinogenic elements are contained in the emitted exhaust gases. The current waste collection methods are just focusing on the load of the selective waste collective vehicle during a collection route. The goal of this research is to find the best solution to use the full storage capacity of the selective waste collecting vehicle with the lowest volume of residual air due to the effectively compressed waste. The closed and uncompressed PET bottles require the largest volume in the waste collecting vehicle. It is essential to minimize the air in the PET bottles to decrease the volume. Different methods have been examined to increase the density of the selectively collected waste. Statistical data have been used to determine the collecting parameters – nowadays, a 15 t waste collecting vehicle, with a 20 m3 load capacity is only gathering 1-1.5 t PET due to the ineffective use of its load compartment. The application of the method herein, enhances the efficiency of the waste collecting vehicle by gathering 4-10 times more waste than currently used methods.

Page Range: 167-171

Description:

Due to continuous developments, the exhausting and unpleasant work done by humans is going to be partly or totally replaced by automated devices. Such developments can be found in the field of transport concerning autonomous and networked vehicles. Although we are at a quite early stage of development, it is highly practical to make plans for a more distant future, i.e. targeting a totally automated selective waste gathering. Apart from the application of smart containers, this study presents alternatives for networked automated selective waste gathering.

Logistic conception for real-time based info-communication system applied in selective waste gathering

István Lakatos Ádám Titrik Tamás Péter

Publication Name: 2017 IEEE 14th International Scientific Conference on Informatics Informatics 2017 Proceedings

Publication Date: 2017-03-27

Volume: 2018-January

Issue: Unknown

Page Range: 203-209

Description:

Decreasing of available raw materials, fossil energy source and new approach made recycling necessary and inevitable. For recycling selective waste areas have been placed, where inhabitants can drop their waste for free. Waste containers have different saturation time, while gathering process is predefined, therefore independently whether it is needed or not they will be emptied. Further problem is that there is no optimization on the way to the container, which results in serious environmental load (noise and air pollution). This study deals with high level route optimization to minimize environmental load concerning noise and air pollution and by the application of real-time communication the appropriate containers are only going to be emptied.

Description:

In the field of municipal waste, expanding cities and growing trend of the population have increasing and problematic effects. Improperly emptied containers jeopardize the possibility of the development of cleaner and more liveable city. Directly occurring problems can be the environmental and road-safety aspects during reaching the containers. Through the application of modern technologies, there are opportunities to apply sign-in-time frequency-based communication. This leads not only to the optimization of the collection route but also to the reduction of the above mentioned problems and problematic effects.

Saturation optimization of selective waste collection vehicles based on real-Time info-communication system

Publication Name: Proceedings of the ASME Design Engineering Technical Conference

Publication Date: 2015-01-01

Volume: 9

Issue: Unknown

Page Range: Unknown

Description:

New technology trends are spreading in selective waste collection, which apply real-Time based info-communication systems defining the saturation of the containers. Merely defining the routes to containers is not enough; saturation of the waste gathering vehicle should also be measured for optimization. In practice, the compression scale of homogenous recyclable waste types is different meaning that saturation optimization cannot be based on this value. This study aims to provide answers to the above-mentioned problem. In order to have an extended analysis the whole city traffic should be taken into account as waste collection traffic may be obstructed by traffic itself. The RPC (Route Planning Center) will apply optimal control for the entire traffic network, which is elaborated by a network analyst pre-calculating network state parameters. The extended approach is based on a determined complex road network modelling technique. Thus further research will be able to integrate the circumstances of the entire traffic network like the definition of traffic network dependent optimal trajectory in chapter 8.

Effect of PET Bottle Compaction on the Saturation of the Waste Container

Szabolcs Fischer Ádám Titrik Mykola Sysyn Dmytro Kurhan

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2026-01-01

Volume: 54

Issue: 1

Page Range: 62-70

Description:

Engineers and users are being pushed by environmental concerns to maximize efficiency while minimizing ecological damage. Waste collection vehicles require fossil fuels during their collection route, as well as when lifting and emptying the containers, even if the design of separate waste collection islands has focused on the idea of recycling. Even in a computer plan–assisted collection, saturated containers may have low waste density, meaning that a sizable portion of the container becomes unusable due to the shape of the waste. To maximize container utilization, this study will investigate the type and compaction potential of each container. The simulation study will provide an answer to the question of how the density of waste placed in the various containers changes as a result of compressing each bottle. The research and development will optimize not only the saturation of the container but also the number of collection routes; in addition to the economic benefits, the environmental load will be reduced. The frequency of lifting and emptying the container will decrease, resulting in reduced maintenance and repair costs for the vehicle′s lifting system and container. It is a misconception that compaction by hand in one place, throughout the diameter of the PET bottle, is the optimum way to increase the efficiency of waste collection. Based on the tests carried out in this paper, foot diameter compaction at full height is considered to be the most appropriate method after the use of a costly compactor.

Page Range: 215-230

Description:

Effective waste management is key to creating more sustainable cities. This study explores a straightforward but impactful way to enhance waste collection efficiency – by optimizing the compaction of metal cans. Various methods of compressing metal containers, including hand and foot compression (middle, full diameter, and full height), were tested to see how much they could reduce the volume of these cans. Our simulations showed that full-height and full-diameter compression were the most effective, significantly increasing container capacity by minimizing empty space. This approach is not only practical but scalable, offering waste management operators a clear pathway to improving resource efficiency. Beyond the immediate benefits of reduced collection frequency and lower fuel consumption, this method contributes to broader sustainability goals by minimizing the carbon footprint associated with waste management. These findings have wide-ranging implications, from urban policy-making to everyday waste disposal practices, highlighting a simple yet transformative step toward a cleaner environment.
