Startups with a sustainability focus


The “Starting Business” start-up service supports students and scientific staff who are starting their own business, from conception to implementation. To date, a large number of sustainability-related start-ups have been successfully founded, and there are already spin-offs of companies.

  • Crafting Future

    Crafting Future was founded in 2020 by students of Leibniz University and currently employs 18 staff. They represent a wide variety of courses of study: Business Administration, Business Information Systems, Social Sciences, Mechanical Engineering, International Business, Economics and Product Design.

    Crafting Future develops and produces measurably sustainable reusable plastic products - Made in Germany. The startup's mission is to challenge the plastics industry, fight waste and the climate crisis with their sustainable alternatives for zero waste. The startups goal is to close material cycles by introducing effective bowl-to-bowl recycling so that resources can be reused again and again. Crafting Future want to push the use of bioplastics to create a sustainable alternative to petroleum.

  • eco:fibr

    Starting off as the voluntary project "Musa Fibra", which was initiated in 2017, the idea evolved into the business start-up eco:fibr GbR in 2020. A limited company (GmbH) spinoff is planned in 2022. The team currently consists of seven people who have studied life science, water- environmental- and coastal engineering, mechanical engineering and economics, among other subjects. eco:fibr has developed an environmentally friendly process for extracting cellulose from pineapple plant remains. This process makes it possible to produce sustainable pulp from a waste product, which is an alternative to conventional pulp made from wood fibers.

    With their mission of "turning waste into purpose", eco:fibr aims to actively combat a throwaway culture by using existing residual materials as raw materials.

    In the long term, eco:fibr wants to recycle as many plant residues as possible worldwide, and supply the alternative raw materials to the paper and packaging industry.

  • Fenntec

    Fenntec builds robots for weed control without the use of pesticides. The robots are designed to replace the prevailing environmentally harmful method of weeding by spraying herbicides. They will make organic food more affordable by replacing time-consuming hand weeding. Currently, the GmbH is focusing on onion cultivation. Soon, the robots will be able to work a field of up to 40 hectares and will be used on a large scale in various crops by organic farmers. A long-term goal is also the autonomisation of their robots. Fenntec GmbH was founded in May 2020. Today, the GmbH employs four people, from the Department of Computer Science and Physics and students of Mechanical Engineering at Leibniz Universität Hannover.

  • Hybrid Indoor Vertical Farming

    Hybrid Indoor Vertical Farming

    The founding team of "Hybrid Indoor Vertical Farming" is developing a vertical system to plant planat-based food in a glass house of the LUH. The goal of vertical farming is to save space and ressources. The special idea of this concept is to use the sun energy to reduce costs. To compensate bad lightning conditions, they use an intelligent LED-system. 

    This way of planting is much more sustainable than conventional farming. The concept solves problems, that the farming industry is facing. They don't use any pesticides and there is no water waste. The concept is also avoiding long transportation ways, because it can be used anywhere and therefore produce locally.

  • HAIP Solutions

    HAIP Solutions is a tech startup from Hannover founded in 2018. True to the motto "TechforGood" they develop, produce and distribute user-oriented hyperspectral imaging (HSI) camera solutions for B2B customers in the field of agriculture/forestry, research, food as well as recycling. The startup wants to develop technology for meaningful purposes. The special cameras offer completely new analysis possibilities, whereby in the field of agriculture or plant breeding, for example, plant stress (e.g. nutrient deficiency, diseases, drought stress) can be detected, which is not yet visible to the human eye. They are also used for sorting machines in the recycling sector, e.g. to separate different types of plastic such as PE, PP or PET and thus be able to produce recycled materials over and over again. The food industry uses hyperspectral technology, for example, to sort out foreign substances in the process chain or to check the quality of food, such as bumps on fruit that cause products to ripen too quickly. In this way, the startup wants to bring more sustainability into the supply chain. HAIP Solutions was founded by four students of Leibniz University. Currently, the team consists of seven people.

  • Hypnetic

    Hypnetic is a technology startup founded in 2019 by three students from Leibniz Universität Hannover. Hypnetic developed a novel energy storage solution based on a hydropneumatic concept for industry and commerce, aiming to accelerate the energy transition by providing cost- and energy-efficient energy storage systems made exclusively of sustainable materials. The technology startup reduces system costs and increases efficiency as well as durability and thus aims to improve the integration and use of fluctuating solar & wind power in the power grids. Company target is a 130 MWh installed storage capacity by 2025. This could actively save about 20,000 tons of CO2 per year compared to the current electricity mix. If the same capacity were realised with batteries, it would require about 50 tons of pure lithium and the same amount of pure cobalt, which are considered critical raw materials due to mining conditions and environmental impact.

  • MAS green ideas

    MAS green ideas was founded in Hannover in 2022. The vision is to offer people, regardless of origin, education or status, low-threshold solutions for a more sustainable life as well as to network with each other with the aim of leaving the world a better place. With the product sustAInable with AI, the starup wants to establish decision heuristics that can be used in personal and digital product advice to understand the individual preferences of customers, promote sustainability and, if necessary, document it in a legally secure manner. The service is initially aimed at the finance and insurance industry because in the field of insurance and finance, due to the high regulatory requirements, sustainability seems to be particularly difficult to grasp. A detailed and individual sustainability profile is generated with just a few, everyday inputs. MAS green ideas works closely with its partner vtmw AG, as a specialised consultancy for technical projects in the insurance industry. The resulting synergies are used for a quick and demand-oriented expansion into other industries, and to make sustainability tangible.

  • Mango.Bananen

    Mango.Bananen is a zero waste company, founded in 2020 by two students in Hanover.

    They produce everything themselves and sell it afterwards at their Onlineshop. The produce for example reusable coffee-filter, teabags and make-up removal wipes. They are all made from 100% natural resources like cotton or linen. The yarn and labels are also made from biological cotton.

    Besides the shop they also present a sustainable way of life on their instagram channel: They are giving tips how to use the products, for example concerning storage or proper use. Their mindset: many small steps can have a big impact!

  • WasteSide

    Team Wasteside´s mission is to encourage people to form sustainable habits. The platform can be used by participants to challenge eachother in different tasks, like "eat vegetarian today". For each challenge you can collect points, which can then be used to get coupons for cafés or other prizes.

    In summer 2023 the project startet at the Contine for the first time. With different challenges around the topic of food waste and sustainable eating habits, students could win coupons for cafés in Hanover. The main prize was a breakfast for two! The project won the Youth-Climate-Competition 2023.

    That´s why the platform is in further development right now. The team is organizing the next round of the challenge at the moment. The plan is to implement the system also at other organisations to reach as many people as possible.
