Alternative of Plastic: Innovations in Bioplastics

published on 09 March 2024

Searching for an alternative to plastic? Bioplastics, made from renewable resources like plants and algae, offer a promising solution. Unlike traditional plastics derived from fossil fuels, some bioplastics are biodegradable, contributing less to pollution and greenhouse gas emissions. However, they currently face challenges like higher production costs and the need for specialized recycling systems. Here's a quick rundown of what you need to know:

  • Sources: Bioplastics come from renewable sources, unlike traditional plastics from oil and gas.
  • Environmental Impact: They're generally more eco-friendly but require careful resource management.
  • Biodegradability: Some bioplastics can naturally decompose under the right conditions.
  • Applications: Bioplastics are being used more in packaging, biomedical products, and daily items.
  • Costs and Production: Higher costs and lower production capacities are challenges for bioplastics.
  • Legislative Support: Government policies can play a key role in promoting bioplastic use.

Quick Comparison:

Category Traditional Plastics Bioplastics
Cost Cheaper but volatile Generally higher but decreasing with scale
Environmental Impact High pollution and emissions Lower emissions; biodegradability varies
Source Non-renewable (oil, gas) Renewable (corn, sugarcane, algae)
End-of-Life Non-biodegradable; recycling challenges Some are compostable; recycling infrastructure needed

Bioplastics could significantly reduce our reliance on traditional plastics, but adoption requires overcoming economic and logistical hurdles. Continued innovation and supportive policies could make bioplastics a viable and sustainable alternative.

Understanding Traditional Plastics and Bioplastics

1. Traditional Plastics

Material Source

Traditional plastics come from things like oil and natural gas, which the earth made over millions of years. We use them faster than they can be made again, so they won't last forever.

Environmental Impact

Making plastic uses a lot of energy and creates pollution, including gases that warm the planet. The whole process, from getting the materials to throwing away the plastic, hurts the environment.


Regular plastics are made to last a long time, so they don't break down easily. This means they pile up in places, causing problems for nature.

Industrial Applications

Plastics are used everywhere because they're cheap, strong, and easy to shape. You find them in things like packaging, buildings, cars, electronics, and everyday products.

Cost and Production Challenges

Making plastics is cheap because we've been doing it for a long time. But, the price of the oil and gas we need can change a lot, making it hard to predict costs. Also, there might not be enough of these materials in the future.

Legislative Support

Countries are starting to make rules to use less plastic and recycle more. But we need more laws to help use more bioplastics and make things better for our planet.

2. Bioplastics

Material Source

Bioplastics are made from stuff that grows back, like plants, algae, and tiny living things, not from oil or gas. You'll often find them made from corn, sugarcane, wood bits, and oils. Because we can grow these again, they're a smarter choice for our planet than using stuff that runs out.

Environmental Impact

Making bioplastics is generally better for the air and uses less energy than making regular plastics. Some types can even naturally break down, which means less trash. However, growing lots of plants just for bioplastics can hurt nature too, so we need to be careful about how we do it.


Certain bioplastics can break down into simpler parts with the right mix of heat and moisture, especially in special compost places. But, some need very specific conditions to break down, so they might still end up not breaking down when thrown away. We need more places and ways to properly get rid of them.

Industrial Applications

Bioplastics are being used more and more, not just for packaging, but also for things like bags, cups, electronics covers, car parts, and medical tools. They're getting better at doing the job, but they usually cost more and aren't as tough or bendy as the usual plastics.

Cost and Production Challenges

Right now, making bioplastics can be 20-50% more expensive because the places that make them are smaller and the process is a bit more complicated. If we put more money into making them and figure out easier ways to get the materials, the cost could go down. Having a steady supply of cheap materials to make them from is also important.

Legislative Support

Countries all over are making new rules to help recycle more and compost. Some laws now say certain plastic items must be made from stuff that can grow back. Money help and tax breaks for making bioplastics are also helping this industry grow. More support from laws and policies can make it easier for bioplastics to become more common.

Environmental Impact Comparison

When we talk about how green plastics are, it's important to look at their whole journey - from where they come from, how they're made, to what happens when we're done with them. Overall, bioplastics are better for the planet than regular plastics, but there's still room for improvement.

Greenhouse Gas Emissions

Making regular plastics from oil and gas uses a lot of energy and creates a lot of pollution - it's like adding 400 million tons of bad gases to the air every year. Bioplastics, on the other hand, are cleaner to make, cutting down bad gases by about 25-50%.

Bioplastics can also break down faster, which means they don't add to the gas problem when they end up in landfills. But, growing the plants we need for bioplastics sometimes uses a lot of resources and can cancel out some of these benefits. Using stuff like algae might be a better way to keep the air cleaner.

Pollution and Ecosystem Impacts

Both kinds of plastics can pollute the air, water, and land during their production. But, making bioplastics is usually less harmful to the places around them.

Also, plastic trash that gets into nature can be really bad. Bioplastics that break down easily can help reduce this problem. But, we still need to make sure they're thrown away properly to avoid hurting the ocean.

Growing plants for bioplastics needs to be done carefully to not harm the environment. Using leftovers from other industries, algae, and even captured carbon to make bioplastics could also help use less land.

The Path Forward

As we get better at making and using bioplastics, they could become a much greener choice than regular plastics. Keeping an eye on how they affect the planet, choosing the right materials, farming in a way that's good for the earth, making sure they can break down properly, and recycling more will help make bioplastics truly beneficial. Laws and investments that support these efforts can speed things up.

Biodegradability and End-of-life

Biodegradability means how well something can break down into nature-friendly stuff like water, carbon dioxide, and plant food under the right conditions. It's a big deal when we talk about whether something is good or bad for the Earth.

Biodegradability of Traditional Plastics

Most of the usual plastics we use, like the ones made from oil, don't break down easily. Things like plastic bags and bottles can stick around for hundreds of years, piling up and causing pollution.

In places like landfills, these plastics can take more than 400 years to even start breaking down a little. And even with sunlight helping, they don't fully go back to nature. They just break into smaller pieces but don't completely disappear.

Biodegradability of Bioplastics

Bioplastics come from plants and other renewable sources, so they can break down better compared to regular plastics. But, not all bioplastics break down fast or easily. How quickly they break down depends on things like how wet or warm it is around them.

Most of these plant-based plastics need to go to special places where they're treated to break down. If you just throw them in your backyard compost, they might not break down properly. Some can take a few years to break down if not treated right.

Bioplastics like PHA and PLA are better at breaking down than regular plastics. PHA can break down in a few months in the right conditions, but PLA might take over a year.

Optimizing End-of-Life Systems

We can use composting to help reduce plastic waste with bioplastics. But, our current recycling systems have trouble sorting them out from other plastics. This means bioplastics might end up where they shouldn't, like in landfills or mixed with other recyclables and messing up the recycling process.

To make things better, we need:

  • Bioplastics that break down well in different places
  • More places that can properly treat bioplastics
  • To teach people how to throw away bioplastics the right way
  • Better technology to sort and recycle bioplastics
  • Encourage recycling bioplastics in a way that they can be used again

Working together on these things can help reduce how much plastic waste we have. But, it's also important to use less plastic in general to really help our planet.

Industrial Applications and Innovations

Bioplastics are slowly becoming more popular in different businesses as they try to be more eco-friendly. Even though regular plastics are still used more because they last longer and cost less, new types of bioplastics are being made that could be good alternatives.

Bioplastics Gaining Ground in Packaging

Packaging uses a lot of plastic, over 40% of all plastic made. Since it's hard to recycle all this plastic, some companies are trying bioplastic packaging to be better for the environment.

  • Tipa creates packaging that can break down in your compost pile using materials like corn starch or sugarcane.
  • Ecovative makes packing foam from mushroom roots that can also be composted.
  • Full Cycle Bioplastics turns leftover food into PHA bioplastics for packaging that breaks down in nature.

Although these bioplastics cost more to start with, they help companies reduce waste and attract customers who care about the environment.

Biomedical Applications Expanding

Bioplastics are also being used for medical stuff like tools, implants, and medicine coatings. Hospitals throw away a lot of plastic, so finding alternatives is important.

PLA is used in 3D printers to make custom medical tools. PHA is used for stitches and meshes that the body can break down after they've done their job. Genecis is working on plant-based capsules for medicine that release the drug slowly.

With more research, bioplastics could make medical care better and reduce plastic waste. The EU wants to use more recycled plastic in medical technology by 2025.

Reusable Food Service Items Reduce Waste

In places like cafes and restaurants, bioplastics are being used for things you can use again and again, like containers and cutlery. This helps cut down on single-use plastics. Companies like Refork and OMAO are making these items stronger so they can be used many times.

These reusable items can handle both hot and cold and can be cleaned in the microwave or dishwasher. While we need more information on how much better for the environment these are, they're a step in the right direction.

Governments are banning single-use plastics, and big food chains are promising to use more sustainable packaging. As more places offer perks for using reusables, bioplastic items could become more common.

Even though regular plastics are still more common because they work better and cost less, the development of bioplastics in different areas gives us hope for less waste in the future. With more research and investment, bioplastics could slowly start to replace oil-based plastics and help us take better care of our planet.


Cost and Production Challenges

When we look at the money and effort it takes to make traditional plastics and bioplastics, we find that bioplastics often have a harder time.

Cost Comparison

  • Making stuff from oil and gas is cheaper because we've been doing it for a long time. The factories and ways we make these plastics are set up to save money.
  • Bioplastics, on the other hand, need a lot of money at the start for research, special machines, and setting everything up. This means they usually cost more, about 20-50% more than regular plastics.
  • As we get better at making bioplastics and do it more, the cost should go down. But we need cheaper materials and better ways to make them first.

Production Capacity

  • Traditional plastics have a big advantage because they have a lot of factories that can make a lot of plastic easily. Everything is set up and ready to go.
  • Bioplastics don't have as many factories, so it's harder to make a lot of it. We need more factories and better ways to make bioplastics if we want everyone to use them.
  • Sometimes, it's hard to get enough plants to make bioplastics because of weather or bugs. Finding a steady supply of plants that we can use at a good price is important.

In short, making bioplastics costs more and is harder right now compared to traditional plastics. We need to put money into making better factories, finding better ways to make bioplastics, and making sure we have enough materials. But for now, traditional plastics have a big lead because they're cheaper and easier to make.

Legislative Support and Policies

Governments around the world are stepping up to fight plastic waste and encourage the use of greener options like bioplastics. But, there's still a lot more work to do for bioplastics to really take off.

Government Regulations on Plastics

Countries are starting to:

  • Say no to single-use plastics like bags and straws
  • Make companies take care of the plastic waste they create
  • Set goals for how much plastic should be recycled
  • Demand that some plastic items are made from stuff that's been recycled before

For instance, the US has a law called the Save Our Seas 2.0 Act that stops plastic beads in cosmetics and helps improve recycling. The EU has a rule, the Single-Use Plastics Directive, that bans certain throwaway plastics.

These rules help create a need for alternatives like bioplastics. But, we still need more laws that specifically support making and using bioplastics.

Bioplastic-Specific Policies

Some places have special rules for bioplastics to:

  • Set clear labels and claims
  • Include bioplastics when talking about recycled content
  • Give money for research and building the right facilities
  • Give tax breaks to companies making bioplastics

For example, Italy gives tax perks for investing in bioplastics. South Korea covers 30% of the cost for new bioplastics equipment.

The EU wants to make a lot more bioplastics by 2030 with rules on buying green products and clear standards. Some US states also don't tax bioplastics.

Still, all over the world, we're missing a full set of rules that help bioplastics compete with regular plastics in all the ways we use them.

Path Forward

To really get bioplastics into the mainstream, we need:

  • More bans on bad plastics to push for bioplastics
  • Rules and perks for using bioplastics in things like packaging
  • Money for looking into bioplastics and building what's needed
  • Clear rules on what makes something biodegradable or compostable
  • Better ways to manage waste and recycle

With the right rules and support at every step, from making to throwing away, bioplastics can lead the way to a world where we use plastics in a smarter, greener way.

Pros and Cons

When we compare regular plastics and bioplastics, each has its own set of good and not-so-good points, especially when we look at how much they cost, how well they work, and how they affect the environment. Here's a quick chart to show you the main differences:

Category Traditional Plastics Bioplastics
Cost ✅ Cheaper to make in big amounts
❌ The price of oil and gas can go up and down a lot
❌ Usually costs more right now, about 20-50% higher
✅ Should get cheaper as we make more
Performance ✅ Really strong and lasts a long time
✅ Can be made to fit lots of needs
❌ Not always as strong or bendy
✅ Getting better thanks to new ideas
Environmental Impact ❌ Can't break down in nature
❌ Making them releases a lot of pollution
✅ Pollutes less when made
✅ Some can be turned into compost
Infrastructure Compatibility ✅ We're all set up to use regular plastics ❌ Need special places to break them down or recycle
Supply Availability ❌ Depends on oil and gas, which won't last forever ✅ Comes from plants that we can keep growing
Maturity ✅ Been around for a long time and we know how to make lots of it ❌ Still pretty new and figuring things out

Good Points About Regular Plastics

  • Cost less to make right now
  • Really strong and can last a long time
  • We already have everything set up to make and use them

Not-So-Good Points About Regular Plastics

  • They don't break down, so they can pile up and pollute
  • Making them releases a lot of harmful gases
  • They rely on oil and gas, which we could run out of

Good Points About Bioplastics

  • They're made from plants, which is better for the planet
  • They usually pollute less
  • Some types can be turned into compost

Not-So-Good Points About Bioplastics

  • They cost more to make right now
  • They're not always as strong or flexible
  • We need special places to break them down or recycle them
  • They're still pretty new and we're learning how to make them better

Bioplastics could help us deal with some big problems like pollution and using up oil and gas. But, regular plastics are still cheaper and work really well for a lot of things. The best choice might depend on what we need the plastic for and how we can take care of the planet at the same time.


Bioplastics are a promising choice instead of regular plastics because they're better for the environment and can do a lot of the same jobs. As we get smarter about making and using them, bioplastics could become a big deal.

Here's what we found out:

  • Bioplastics usually don't harm the planet as much as regular plastics. They need less energy to make and don't let out as much bad air.
  • A lot of bioplastics can break down into natural stuff if we handle them right, which means less trash hanging around. But, we need to get better at dealing with these materials after we're done using them.
  • Bioplastics are getting better and can be used for more things now. But, regular plastics are still tougher in many situations.
  • Right now, bioplastics cost more, but they could get cheaper as we make more of them. Making them less expensive also depends on finding easier ways to produce them.
  • Laws that help the environment and encourage using green products are really important for getting more people to use bioplastics.

Switching to bioplastics isn't easy, but we need to try because plastic waste is a huge problem. If everyone from companies to governments to regular folks works together, bioplastics could replace a lot of the regular plastics we use.

Here's what needs to happen:

  • Keep coming up with new ideas to make bioplastics better and cheaper
  • Set up systems for dealing with bioplastics once we're done with them
  • Make rules clear about what makes bioplastics good for the environment
  • Teach people how to throw away bioplastics the right way and help them choose to buy them
  • Make more laws and programs that support using bioplastics, like banning harmful plastics, taxing them, or giving rewards for choosing green options

The way to less plastic pollution will need a bunch of different solutions. But because bioplastics come from renewable sources and often can break down naturally, they could lead the charge in making a world where we use plastics in a smarter, cleaner way. Their progress points to healthier oceans, less bad air, and fewer trash piles.

What are plastic alternatives bioplastics?

Bioplastics are a type of plastic made from things that grow, like plants, instead of oil or gas. Some common types are PLA (which comes from corn starch or sugarcane) and PHA (made from vegetable oils or fats).

Here’s how they're different from regular plastics:

  • Origin: Bioplastics are made from things that can grow back, while regular plastics come from oil and gas.
  • Biodegradability: Some bioplastics can break down naturally in the environment, but regular plastics can't.
  • Price: Making bioplastics usually costs more, about 20-50% higher than making regular plastics.

In short, bioplastics are a more earth-friendly choice than regular plastics, but they're still more expensive.

What are the alternatives to using plastic?

Instead of using plastic once and throwing it away, we can use:

  • Metal, glass, and ceramic containers for keeping and carrying food
  • Cardboard and paper for packing stuff
  • Bags made from natural materials like cotton for shopping
  • Wooden spoons and forks
  • Wraps made from beeswax instead of plastic cling film
  • Drink bottles and cups that you can use over and over

Choosing items that last longer and are made from materials like metal, glass, and natural fibers can help us use less plastic.

Can bioplastics replace plastics?

Bioplastics have the potential to take the place of many regular plastics, but there are still challenges with cost, how well they work, and getting the systems in place to handle them properly. With more development and support from policies, bioplastics could replace a lot of traditional plastics. For now, it’s also important to use less plastic overall, along with using bioplastics.

What alternatives do we have to replace non biodegradable plastic that has accumulated in our streams rivers and oceans?

To tackle plastic pollution, we can:

  • Ban harmful plastics: Stop using plastics that are bad for the environment and hard to recycle.
  • Encourage alternatives: Use laws and education to promote eco-friendly options like reusable items, bioplastics, and cardboard.
  • Improve waste and recycling systems: Invest in better ways to collect, sort, and recycle plastic waste.
  • Develop cleanup solutions: Support technologies that can clean up plastic from our waters.
  • Rethink plastic usage: Change how we use plastic in our daily lives to reduce waste.

By taking these steps, we can fight plastic pollution, protect our planet, and move towards a more sustainable way of living.
