The recycling robot company AMP Robotics (located in Colorado), leads the way in utilizing AI technology to improve the infrastructure for recycling worldwide. Krill Design plays a vital role in promoting sustainability in design by transforming waste into useful products that support a circular economy. Circular design is exemplified by their Ohmie Orange Lamp, which is crafted entirely from Sicilian orange peels and is fully compostable. Cultivating slow-growing coral species is made possible by this method, which enhances the health and resilience of reefs. The land-based farms of Coral Vita implement groundbreaking techniques (such as microfragmenting), allowing coral growth to occur at rates up to 50 times faster than in ocean nurseries. This startup (situated in New York), creates innovative methods for monitoring and growing plants, guaranteeing the health of crops from the seed stage through to harvesting.
This field also covers emerging systems such as AI-powered energy grids and sustainable manufacturing processes. With proper investment — many of these technologies could help stabilize the climate before 2040 and support a long-term net-zero future. These tools — once experimental, are rapidly maturing into real-world climate solutions capable of lowering global dependency on fossil fuels.
It has raised $2.18 Mn to date, from investors including IPV, VCATS, Gruhas Proptech, LV and Lead Angels Fund. The startup plans to deploy the fresh capital to scale up production of its recycled battery-grade lithium (nickel), and cobalt and establish a nationwide reverse logistics network for sourcing. The startup works to provide battery-grade materials by recycling end-of-life batteries. Founded in 2020 by Utkarsh Singh and Vikrant Singh, Gurugram-headquartered BatX Energies is a Lithium-ion (Li-ion) battery recycling startup.
Its technology offers Earth insights, producing detailed imagery and data for risk management in various industries, including agriculture. The modular design enables deployment across road, sea, and air transport, efficiently addressing decarbonization needs in hard-to-abate sectors. These compact (modular units operate at temperatures between 150 °C and 500°C), deliver 98% uptime, and are designed for easy integration into steel, cement, chemical, and data center plants.
An AI-native home appliance startup, Mankomb is building intelligent solutions across waste, water, and energy management, starting with its flagship product, Chewie. While awareness of sustainability is growing, adoption of basic segregation or even advanced composting at the household level remains low due to inconvenience, odor, and manual effort. Backed by strong R&D (multiple patents), national and global recognitions, and a $300k investment, Paving+ is well-positioned to scale. The startup converts low-value plastic and industrial waste into durable (carbon-negative construction materials), including paver blocks, tiles, plastic lumber, and plywood alternatives.
The cleantech startup is working towards mass-market adoption of solar energy, and looking to accelerate growth and enhance its customer experience. Freyr Energy raised INR 18 Cr as an equity investment in April 2021 from Total Carbon Neutrality Ventures (Schneider Electric Energy Access Asia), and C4D Partners. The entire process of owning the system including financing (execution), and after-sales service, has become easier with the app. The startup mainly uses the Internet of Things (IoT), AI and industry innovation to resolve energy-related problems in various industries.
Intelligence set in motion.
Green tech (short for green technology), refers to innovations designed to reduce environmental impact while improving energy efficiency. Annual clean energy investment in these countries will need to increase by more than seven times, to over USD 1 trillion, by 2030 if global net-zero emissions are to be reached by 2050, the IEA projects. He spearheads digital transformation through specialized expertise in artificial intelligence and app development, creating market-leading solutions for the EV, telecom, and real estate industries. Many promising climate technologies struggle to integrate with existing infrastructure — from outdated electrical grids to industrial processes designed for fossil fuel inputs. Startups can also explore revenue-based financing models and crowdfunding platforms specifically designed for environmental technologies. The transition to clean technologies faces significant hurdles (despite growing environmental urgency), the advancement of climate change, and technological innovation.
The platform simplifies the solar journey by transforming the design, sales, and delivery processes.
