From 14-20 November 2021, Systems & Components will draw a picture of the present and future of mobile automation

The B2B platform for the supplier industry of the entire off-highway sector, which will be held for the fifth time as part of AGRITECHNICA at Hanover exhibition grounds, is supported by the guiding theme: Green Efficiency – inspired by solutions. This topic will be discussed among engineers and technical experts as part of the ‘Future Lounge’ technical programme, the digital trade forum of Systems & Components.

Green efficiency - inspired by solutions, the guiding theme of Systems & Components, aptly describes the situation in which the designers of mobile machinery from agriculture, the construction industry and mining find themselves. The vehicles are not only exposed to extreme weather conditions but also environmental conditions like temperature and contaminants, which place enormous demands on the robustness of the technologies and materials used.

Added to this are the growing demands for digitalisation and automation of the individual assemblies used in work machines. Intelligent mechatronic assemblies are increasingly being integrated to improve the precision and safety of mobile machinery. Above all, however, it is the desire to increase productivity and reduce the ecological footprint that now drives off-road technology developments.

Requirements for the technology drivers of tomorrow

The experts agree on one thing: Internal combustion engines will remain an important pillar in heavy off-highway applications in the medium to long term. They will continue to be used even after petrol engines in passenger cars have been replaced by alternative concepts. However, the ever stricter exhaust emission limits pose an increasing challenge for manufacturers of heavy-duty engines. With the EU Stage V emission standard introduction, the permissible emission values have been pushed down even further. At Systems & Components, this will result in a more energy-efficient engine portfolio that combines emission specifications and market requirements.

In order to comply with the particle number limit, which has been a legal requirement since 2019, exhibitors are focusing on modular exhaust after-treatment, Selective Catalytic Reduction (SCR) catalysts and particulate filters. On the agenda in Hanover, there are further technical concepts that aim to achieve maximum flexibility in fuel selection - an important aspect on the way to a carbon-neutral future that is being discussed in the digital trade forums of the ‘Future Lounge’. The presentations will also deal with the use of so-called e-fuels or power-to-liquid fuels, as well as the large area of e-mobility. Modular scalable drive trains and downsizing promise measurable cost and emission advantages.

Ready for electrification

Systems & Components shows how off-highway electrification works in practice. This trend is reflected at the trade fair grounds in hybrid concepts that combine smaller and lower-emission diesel engines with electric drives and lithium-ion batteries. The solutions represent a further option, especially for low-load applications in material handling and compact construction machinery. The electric motor is mechanically connected to the diesel engine via a gearbox with an integrated disconnect clutch. This also enables the vehicle to operate purely electrically. Another advantage of hybridisation is implementing additional functions for energy recovery or operating auxiliary units such as the Power Take-off (PTO) electrically. The system suppliers' electrification solutions range from motors and inverters to hydraulic pumps, transmissions, and battery solutions. In the ‘Future Lounge’, the digital trade forum of Systems & Components, this topic is discussed in-depth among engineers and technical experts.

M2M communication in the field

Designing digitalisation as a sustainability engine for agriculture is another aspect that Systems & Components is aiming at with its guiding theme “Green Efficiency - inspired by solutions”. The prerequisite for this is the intelligent and targeted management of agricultural land - in line with precision farming, a mega-trend which the exhibitors in Hanover will address with intelligent solutions. The aim is always to obtain a differentiated knowledge of all essential aspects of the field and crops with the help of various sensor systems. As a result, the demands for precision, safety and performance in the field are increasing.

Seed drills, fertilising, and harvesting machines are being digitally upgraded step by step. They are being networked with the tractor and act increasingly autonomously. The advent of Machine to Machine (M2M) communication not only makes it possible to control agricultural implements from the tractor cab but with TIM, the Tractor-Implement Management system, it also works the other way round. Already today, seed drills, sprayers or balers equipped with TIM technology can give commands to a tractor via the ISOBUS to independently optimise their work flow. Even though by no means all devices are equipped with this feature in practice: The steadily growing number of electronically controlled components is pushing the ISOBUS architecture to its performance limits. Ethernet-based backbones are paving the way for high bandwidths, as required for real-time M2M communication or cloud-based diagnostic functions. Which bus system is the future - the high-speed ISOBUS, which is currently being worked on at as a priority, or the open source protocol POWERLINK - is likely to be one of the main topics of discussion at the B2B trade fair.

Smart sensor technology takes over driver assistance

In addition to GPS positioning systems, the prerequisite for autonomous and semi-autonomous working machines are above all sensors for short and long-distance monitoring. Their task is to detect objects and persons in the vicinity, relieve the driver, and, therefore, ultimately prevent injury and damage to man and machine. In the development of 3D cameras, LiDAR sensors or laser scanners, ultrasonic and tilt sensors, encoders and inductive proximity sensors, as well as intelligent assistance systems, the exhibitors at Systems & Components rely on a broad range of technologies. Recent innovations include steer-by-wire technologies, where the steering column can be removed and replaced, allowing smaller, more precise mechanisms such as joysticks or mini steering wheels. The result is solutions that provide additional flexibility in cockpit design and help reduce the operator’s workload, therefore improving productivity.

On the way to autonomous working machines

It will take several more years before electrically driven and autonomously driving working machines dominate construction sites and agricultural land. With industry know-how and a broad portfolio of digital technologies, the exhibitors at the Hanover trade fair grounds will accompany the upcoming change in the off-highway sector. Technically, the way to automated driving is already paved by assistance systems and sensor technology. But which approaches promise the greatest success for practical application? From 14-20 November 2021, Systems & Components will provide answers to this question and invite discussion on new technologies’ opportunities and challenges.

Crayfish provide a nutrient-dense, low-impact protein source that requires minimal feed.

Aquaculture

The Philippines has taken a decisive step toward strengthening its position in global aquaculture with the launch of its largest crayfish nursery—a flagship development designed to scale production of the high-value Australian Redclaw crayfish.

The project, built through the partnership of Farm Fresh Early Catch Inc., Taiwan’s Da Shin Biotech Ltd., and the Department of Agriculture’s Bureau of Fisheries and Aquatic Resources (DA-BFAR), marks a defining moment for the country’s fast-growing aquaculture sector.

The new nursery will focus on mass-producing Cherax quadricarinatus, a resilient and fast-growing species prized by both domestic and international markets. Government officials say the initiative supports national efforts to strengthen food security while boosting long-term livelihood opportunities in rural areas.

Agriculture Secretary Francisco P. Tiu Laurel Jr., in remarks delivered by Assistant Secretary and spokesman Arnel de Mesa, highlighted the power of collaboration behind the facility. “Built through the partnership of Farm Fresh Early Catch Inc., Da Shin Biotech, and the DA-BFAR, this nursery shows that when government, private innovators, and fisherfolk come together, progress stops being a dream—it becomes our shared reality,” he said.

Tiu Laurel added that crayfish aquaculture “opens new doors for our fisherfolk—bringing in more income, more livelihood, and more food on our tables,” while underscoring the need for responsible production and adherence to BFAR’s ecological protection guidelines. Every pond, he said, must “nurture care, discipline, and respect for the balance of our ecosystems.”

Situated in Candaba - a wetlands area renowned for its freshwater abundance—the 1,280-square-metre facility features 16 tanks capable of producing up to 48,000 fry every two weeks. It also introduces advanced water-recycling systems that help reduce waste and conserve freshwater, addressing one of the most common environmental criticisms of aquaculture operations.

The nursery will supply Farm Fresh’s existing 3-hectare grow-out ponds, which already produce around 30 tonnes of market-ready crayfish each year. It will also support a broad network of partner growers as production expands nationwide.

From 2026, Farm Fresh plans to roll out large-scale grow-out operations covering 1,500 hectares in Luzon and 750 hectares each in the Visayas and Mindanao. When these sites reach full capacity, they are projected to deliver more than 1,200 tonnes of crayfish every six months—volumes that could position the Philippines as a competitive player in the regional and global aquaculture market.

Crayfish provide a nutrient-dense, low-impact protein source that requires minimal feed. The project is expected to generate over 3,000 direct jobs and stimulate additional enterprise in farming communities.

The launch marks the beginning of a world-class crayfish industry designed to place the Philippines firmly on the global aquaculture map.

Hydroponic Systems is helping greenhouse growers tackle the challenge of optimising microclimates without compromising light or productivity.

In warm regions, particularly for heat-sensitive crops like strawberries, tomatoes, and peppers, managing radiation, temperature, and heat stress is critical. Heat-diffusing mesh has become an essential tool in balancing light levels and reducing heat buildup inside greenhouses, proving to be one of the most effective solutions for these challenges.

The mesh works by partially blocking infrared radiation while allowing useful diffuse light to pass through. This reduces internal temperatures, alleviates heat stress, and sustains photosynthetic activity. According to Hydroponic Systems, this approach helps "improve fruit quality, reduce plant stress, and stabilise growing conditions," especially during periods of high radiation.

The mesh achieves this through a combination of light diffusion and thermal reflection. The diffusion process disperses light, preventing hot spots and ensuring even distribution of photosynthetically active radiation (PAR) across the plant canopy. This enables middle and lower leaves to contribute more effectively to photosynthesis. Aluminium particles embedded in the polymer structure reflect infrared radiation, which helps control heat accumulation. The result is a more stable greenhouse environment with fewer temperature spikes.

Hydroponic Systems recommends the Agrifresh aluminium thermodiffuser mesh as a proven solution. This patented fabric creates an effective thermal barrier without compromising light quality. According to the company, it works best in professional greenhouses of around half a hectare or more, where managing temperature and radiation is crucial for maintaining high yield and quality.

In practice, reduced infrared radiation leads to lower heat accumulation and fewer temperature fluctuations, especially during critical growth stages. Increased diffuse light improves PAR distribution, supports stable photosynthesis, and reduces the risk of heat stress. As a result, growers experience "more uniform fruit, fewer deformities, and better colour and firmness."

Strawberries, in particular, show significant benefits, with improved uniformity, firmness, colour, and crop stability. Similar positive trends have been observed in tomatoes, peppers, cucumbers, and other crops.

For optimal performance, proper installation is key. Correct height, tension, and orientation affect the mesh's effectiveness. Hydroponic Systems advises careful integration with ventilation systems for best results.
