• Features: Reduces food waste from households

The Lomi indoor composter uses an intensive process to turn your food waste into dirt with a press of a button. This is hugely impactful for the environment. The USDA estimates that 30-40% of the food supply is wasted every year, and Feeding America clarifies that food waste in our homes makes up about 39% of the overall amount or 42 billion pounds of waste a year.

Enter the Lomi, which tackles that problem with a solution you can place on your countertop. This gadget has fascinated me for a while. You fill the Lomi about 75% full with food waste and it not only processes that waste in a usable way with the right setting and keeps it out of landfills, but it also reduces the mass of the waste.

• Price: $230
• Features: Self charging | Powered by natural and artificial light | On ear | Wireless | 80 hours of battery life

The Adidas RPT-02 SOLheadphones are incredibly innovative, using Exeger's Powerfoyle™ light cell material to convert natural and artificial light into battery life. The on-ear, wireless headphones self-charge by taking in light and giving you up to 80 hours of stored playtime in exchange. The price point is similar to what you'd pay for a pair of good Beats or Sony headphones, but you don't have to worry about charging and you get a lot more listening time. The RPT-02 SOL are partially built from recycled plastics, upping their environmentally-friendly footprint even more. According to Adidas, 87% of the plastic in the product is post-consumer recycled PC-ABS and recycled nylon (excluding plastics in electronic components) and only 51% of the overall product is made of plastic. The headphones are sweat-proof and splash-proof and, if you need to, you can remove and wash the inner headband and ear cushions.

• Price: $58+ with discounts
• Features: Plants grow faster than when grown in soil | Grow on your kitchen countertop | No pests | Automatic watering | Grow fruits, veggies, flowers, and herbs year-round

If you live in an apartment or a small space, it can be hard to grow plants indoors. Soil is messy and hard to clean, and it attracts unwanted pests into your home. Even if you have a backyard, you too might not want to grow plants for fear of attracting pests. A hydroponic indoor garden allows you to circumvent seasonal and space limitations and grow fruits, veggies, herbs, and flowers year-round, albeit in small quantities, from the comfort of your own home. It's 30-50% faster to grow plants hydroponically instead of in soil, and you don't need to worry about the plants getting sunlight either: Hydroponic systems come equipped with LED lights that simulate natural sunlight, a water reservoir, and a circulation system. Even if you go out of town, you don't need to worry about watering your plants or turning on the LED lights, as the lights come with automatic timers and the water reservoir simply has to be filled in order for water to automatically circulate. This is a cool system built with a purpose. The only downside is that the quantities of plants grown can be low, so you may be better off growing herbs instead of larger plants. You also have to keep purchasing pods to keep using the machine, which is similar to buying seeds again and again for an outdoor garden.

• Price: $0 to $299 for experiences and $199 to $1,299 for getaways
• Features: Versatile | Gives the recipient choices | Adjustable to your budget

Gift a sustainable getaway for you and your significant other.

When you gift a Tinggly gift box, you're giving someone the freedom to choose from a wide range of experiences or getaways in more than 100 countries. Depending on your budget, you can go for a $0 free experience, or purchase an experience box ranging from $59 to $299. The Be my Valentine box offers more than 1,000 experiences in over 100 countries, including swimming with the manatees in Florida, taking surfing lessons in California, enjoying a sightseeing sail trip for two in Maine, experiencing a gourmet five-course dinner in Rio de Janeiro, visiting the Harry Potter studio in London, touring a Game of Thrones experience in Croatia, or visiting a Beijing opera night show. There's no expiration date and each gift box plants trees.

You can select either an experience box or a getaway box -- the latter includes a hotel stay of the recipient's choosing. A getaway box can be more expensive, ranging from $199 to $1,299. You can purchase an additional $10 gift box, so that your gift recipient has a physical gift to open, or you can send the gift as an eVoucher via print or email. The latter option is more eco-friendly and it's good to have as backup in case the person loses the gift box.
