Earth Rover, a UK based agri-robotics company and Agri-EPI Centre member, has developed the LightWeeder to solve key challenges faced by laser-based weeding systems


The LightWeeder is said to be the world’s first eye-safe, herbicide-free, carbon-neutral, commercially viable weeding system. The LightWeeding technology uses semiconductor LEDs to solve key technical, safety and commercialisation challenges faced by laser-based weeding systems.

The LightWeeder is part of CLAWS (Concentrated Light Autonomous Weeding and Scouting), an agri-robot that can kill weeds using a unique concentrated light method, and can also scout fields to obtain a complete data map of all crops after planting, showing the crops exact location, size, and any early signs of disease.

The main features of CLAWS are:

  • Weeding – chemical-free and inherently safer than laser weeding. No till and no crop damage and can be used in any conditions without compacting the soil.
  • Scouting – In-depth analysis of crops to allow better harvest predictions and increased yields.

The complete system is ultra-lightweight at 300kg, meaning it requires low amounts of energy to run, and is also claimed to be cheaper and more environmentally friendly than many of its competitors. The system currently runs on batteries and in future, solar panels therefore uses no fossil fuels and help farmers meet their net-zero targets.

With increasing types of chemical-resistant weeds, a significant downturn in availability of hand labour plus a shift in society towards more organic options, now more than ever there is a need to change the way we farm. A recent report by Rothamsted Research shows weeds pose an unprecedented threat to our food security and highlights the need to diversify weed control as an urgent priority.

As explained by John Taylor, farm director at Pollybell Organic Farm, “The key element here is that the LightWeeder not only makes chemical-free farming more effective but it also solves the huge issue farmers are facing today in terms of the huge loss in the labour force. Being able to weed fields autonomously means that food production doesn’t just grind to a halt.”

According to Earth Rover, LighWeeder is energy-efficient and no-till and does not cause damage to drip irrigation or crops. It is also not dependent on soil conditions and does not enable weeds to develop resistance.

Equipment

Zoomlion Heavy Industry Science & Technology Co., Ltd. took centre stage at the 4th China-Africa Economic and Trade Expo in Changsha, China, from 12 to 15 June, showcasing its latest agricultural and engineering machinery solutions tailored specifically for the African market

Since making its entry into Africa in 2007, Zoomlion has played an integral role in infrastructure development and agricultural modernisation across the continent. The company has also been committed to nurturing local talent, evident in its ongoing technical training programmes, such as those provided to Ugandan farmers to enhance agricultural skill sets.

At the trade expo, Zoomlion displayed a comprehensive line-up of machinery, ranging from construction cranes and earthmoving equipment to aerial work platforms and advanced agricultural machinery. These products are engineered to withstand and perform efficiently in Africa’s diverse and often demanding working conditions.

Zoomlion’s footprint in Africa has expanded significantly over the past 18 years. The company has delivered more than 10,000 units of equipment to markets across the continent, establishing itself as one of Africa’s leading machinery suppliers. In addition to setting up subsidiaries in key markets like South Africa, Nigeria, Kenya, and Tanzania, Zoomlion has developed a robust after-sales infrastructure. This includes spare parts centres in Algeria and South Africa, a joint-venture manufacturing plant in Algeria, and an expanding network of dealers and service providers across the region.

The company has also been instrumental in supporting critical infrastructure projects throughout Africa. These include Egypt’s New Administrative Capital—home to Africa’s tallest skyscraper at 385.8 metres—the Julius Nyerere Hydropower Project in Tanzania, which boosts the country’s energy capacity nearly fourfold, and the N'Djamena Stadium in Chad, designed to host international sports and cultural events. Another notable contribution is the Rosso Bridge, linking Senegal and Mauritania, which will enhance regional trade and connectivity.

Zoomlion’s growth trajectory in Africa continues to accelerate. Sales in the first quarter of 2025 alone accounted for 60% of the total recorded in 2024, underlining rising demand for its solutions. As of May 2025, the company’s Africa team comprised over 300 employees, with more than 90% of them being locally hired—demonstrating Zoomlion’s commitment to job creation and skills development in the region.

Technology

Entocycle, a UK-based developer of insect farming technology that transforms food waste into sustainable protein for animal feed, has collaborated with Siemens to launch the country’s first digitalised insect farm showroom

The facility is uniquely located beneath four Victorian railway arches in central London.

Focused on creating a sustainable protein alternative, Entocycle chose the high-profile London Bridge area to boost visibility, attract top talent, and engage potential investors in its innovative approach to circular food systems.

Before construction began, Entocycle used Siemens’ digital twin technology to create a virtual model of the site. This simulation helped maximise the use of the complex arch-shaped space and minimise construction errors, saving time and costs.

The site has since undergone a full digital transformation and now runs on Siemens AI and automation systems. Advanced technologies integrated into the facility include robotic arms, machine vision systems that monitor 3,000 larvae per second with up to 100% accuracy, and climate-controlled chambers. These upgrades have significantly enhanced production by reducing larvae growth time and improving survival rates by 30%.

Now in operation for a year, the facility has demonstrated that insect farming can address two major environmental challenges: cutting the UK’s annual 10.7 million tonnes of food waste (of which 30% is lost through supply chain inefficiencies) and reducing reliance on 3.3 million tonnes of imported soy used for animal feed.

With proof of concept established, Entocycle plans to expand its model to industrial scale, aiming to support farms, agri-businesses, and waste management companies in cutting emissions and rethinking protein supply chains.

Matt Simonds, managing director at Entocycle, said: “We’ve spent a decade developing this concept, which has grown from equipment pieced together from hardware retailers to the bespoke and highly advanced factory we’re running today. The London Bridge centre proves our concept, which leverages the black soldier fly as nature’s recycler, that can be scaled around the world to help tackle the dual issue of food waste and sustainability issues in animal feed supply.

“Insect farming is an exciting emerging industry, and our vision is to be the go-to provider of technology to customers alongside our partner Siemens. In 10 years’ time, we expect Entocycle-designed farms to be processing millions of tonnes of food waste around the world, saving millions of tonnes of carbon emissions with it. Partnering with Siemens to deliver our solution internationally provides us with the trust and scalability we need to deliver on our global ambitions.”

Keith Thornhill, head of food and beverage for UK & Ireland at Siemens said: “Entocycle has created the blueprint for high-tech insect farming. It’s successfully applied modern manufacturing technology to its highly niche subject of rearing black soldier flies. And the outcomes are clear to see in increased insect survival rates and slashing the time staff would spend counting insects.

“It’s a fantastic concept ready to be delivered to customers around the world, regardless of site size and location. We’re proud to support it as a great example of technology with a purpose in addressing crucial sustainability challenges.”
