Creative Ways To Recycle Plastic Lattice: Reuse And Upcycle Ideas

Plastic lattice is a popular material for landscaping due to its durability, ease of cleaning, and resistance to insects and rotting. However, its proper disposal or recycling is essential to minimise its environmental impact. While plastic can take hundreds of years to biodegrade, recycling it can help conserve natural resources and energy. Before recycling, plastics are sorted by resin type or colour, and then undergo mechanical or chemical recycling processes. However, not all plastic lattice may be widely recyclable, and proper disposal methods should be followed to avoid causing harm to the environment.

How to Recycle Plastic Lattice

Cutting plastic lattice

Preparation:

Before you start cutting, it is important to take the necessary safety precautions. Put on protective gear, including plastic safety glasses to shield your eyes from any debris and work gloves to protect your hands from potential splinters or chips. Measure your project space accurately using a measuring tape, and mark the lattice with a pencil and straightedge to indicate where the cuts need to be made. Clamping the lattice in place will also help stabilise it during the cutting process.

Choosing the Right Tools:

The type of saw and blade you choose will depend on the material of the lattice and the precision required. For plastic lattice, it is recommended to use a circular saw with the appropriate blade. If you are working with vinyl lattice, a fine-toothed blade is ideal to prevent chipping. You can install a fine-tooth paneling blade backwards in your circular saw, which will melt through the vinyl smoothly without causing ragged edges. Alternatively, you can use a reciprocating saw (Sawzall) or jigsaw with a medium-toothed blade. If you prefer using a handsaw, opt for one with fine teeth to achieve a clean cut.

Cutting Technique:

When using a circular saw, set the blade depth slightly thicker than the lattice panel to avoid cutting into your work surface. Adjust the blade depth by releasing the blade lever on the back of the saw. Hold the saw against the lattice and let the blade dip below the lattice's level before securing the depth. Follow the marked line with the saw at a steady pace to avoid chipping. If you are using a handsaw, maintain a slow and steady hand to keep the cut straight. For curves, a jigsaw with a fine-toothed blade is recommended, and you should go slowly to maintain control. Remember to remove any staples from the lattice beforehand to prolong the life of your blades.

Post-Cutting Touch-ups:

After cutting the lattice, you may encounter rough edges. To smooth these out, use fine-grit sandpaper and gently sand the cut edges. Be cautious not to over-sand, as this could result in removing too much material or rounding off the edges excessively.

Preparing plastic lattice for recycling

Next, you will need to disassemble the plastic lattice by removing any staples, nails, or other fasteners. Manufacturers often use these fasteners to hold the lattice together, but they need to be separated before recycling. Use a flat screwdriver or a similar tool to carefully pry and remove the staples and nails. Make sure to wear protective gear, such as gloves and safety glasses, during this process to prevent any injuries.

Once the lattice is disassembled, separate the plastic lattice from any other materials that may be attached or combined with it. This could include dividers, frames, or other components made from different materials. Use a straightedge and a pencil to mark the separation points, and then use a saw to carefully cut and separate the plastic lattice from the other materials.

After separation, cut the plastic lattice into smaller pieces. You can use a circular saw or a reciprocating saw for this step, ensuring that the blade is appropriate for cutting plastic. Cut the lattice into uniform-sized pieces that will be easier to handle and process during recycling. Remember to wear protective gear and follow safety precautions during the cutting process.

Finally, collect and sort the plastic lattice pieces into containers or bins based on their type. Different types of plastic will need to be recycled separately, so check for any recycling symbols or numbers on the lattice to identify its specific type. If your local recycling program does not accept a particular type of plastic lattice, you may need to dispose of it separately or find an alternative recycling centre that accepts it.

Mechanical and chemical recycling processes

Plastic recycling technologies reprocess or remanufacture plastic waste for reuse. The dominant technology for plastic recycling is mechanical recycling, which uses physical processes such as sorting, grinding, washing, separating, drying, and re-granulating to recover plastics that can be substituted for virgin, or new, plastics. Mechanical recycling prepares waste polymers for reuse without significantly altering the chemical structure of the material. The separated, single-polymer stream is washed, granulated, and then re-extruded to make recycled pellets ready for moulding applications.

However, mechanical recycling has its limitations. The technology is expensive and labour-intensive, and the recycled plastics are generally lower quality than virgin plastics. As such, the industry is considering advanced recycling technologies, such as chemical recycling, as an alternative or complementary process.

Chemical recycling is a broad term for a range of emerging technologies in waste management that enable the recycling of plastics that are difficult or uneconomical to recycle mechanically. It uses heat, chemical reactions, or both, to recycle used plastic into virgin-equivalent plastic, fuel, or other chemicals. Chemical recycling can be divided into three categories based on the position of their outputs in the plastics supply chain:

• Depolymerisation and feedstock recycling: This process breaks down long hydrocarbon chains in plastics into shorter hydrocarbon fractions or monomers using chemical, thermal, or catalytic processes.
• Conversion: This process focuses on converting polymers into smaller molecules through techniques such as pyrolysis and gasification. Pyrolysis, sometimes called "plastics-to-fuel," involves heating plastic waste to high temperatures (300-900°C) in an oxygen-absent environment, turning plastic waste into a synthetic crude oil that can be refined into diesel fuel, gasoline, heating oil, or waxes. Gasification also heats plastic waste to high temperatures (500-1300°C) but in a low-oxygen environment, converting plastic waste into synthesis gas or "syngas," a fuel mixture containing hydrogen and carbon monoxide.
• Other chemical recycling technologies: These technologies aim to improve plastic recycling rates and divert plastic waste from landfills or incineration by further extracting value from polymers.

Removing old lattice

Firstly, it is important to gather the required tools and materials. You will need a flat pry bar, a reciprocating saw or a small carpenter's cat's paw, a screwdriver, protective gear such as gloves and goggles, and a flat surface for cutting. Ensure that you have a safe and clear workspace before starting.

Next, put on your protective gear, including gloves and goggles, to safeguard yourself from any debris or sharp edges. Inspect the old lattice to identify any staples, nails, or other fasteners. Use the screwdriver or small carpenter's cat's paw to gently pry off and remove these fasteners. Be careful not to damage the surrounding structures, such as the porch, deck, or support columns.

If the lattice is particularly stubborn or difficult to remove, you can use the reciprocating saw to cut through it. This will weaken the structure of the lattice and make it easier to remove in smaller pieces. Ensure that you are confident in using a reciprocating saw safely, or consider hiring a professional if you are uncomfortable with this step.

Once the lattice is removed, dispose of it properly. Lattice can often be recycled, so check with your local recycling guidelines to determine the appropriate method of disposal.

Finally, inspect the area where the lattice was removed. Ensure that there is no remaining debris or damage to the surrounding structures. If necessary, make any needed repairs or touch-ups to the area before installing new lattice or completing your desired project.

Remember to take appropriate safety precautions during the entire process, and do not hesitate to seek professional assistance if needed. Removing old lattice can be a challenging task, but with careful planning and execution, it can be accomplished successfully.

Attaching lattice to frames

Planning and Preparation:

First, measure the openings between the columns or posts of your deck or porch. The completed frames should be 1/2 inch narrower than the overall width and 1 inch shorter than the height to allow for a proper fit. Clear any debris or vegetation from the area and level the ground if necessary. Check the support structure of your deck or porch and address any issues before installing the lattice.

Assembling the Frames:

Assemble wooden frames that fit the openings you measured. Each frame should have four sides and a center stile. The center stile provides support and helps to secure the lattice in place.

Cutting the Lattice:

Before attaching the lattice to the frames, you need to cut it to the appropriate size. Measure the dimensions of the frames and cut the lattice panels using a sabre or circular saw. Allow for a small buffer of 0.25 inches on each side to accommodate expansion and contraction due to weather conditions.

Now you are ready to attach the lattice to the frames. Lay the frames face down and place the lattice over them. Secure the lattice to the frames using 1-inch pan head screws driven through washers. Drill clearance holes that are slightly larger than the screw shanks to allow for the expansion and contraction of the lattice. Leave a 1/4 inch gap on all sides between the edge of the frame and the lattice.

Finishing Touches:

Before installing the framed lattice panels, you can paint or stain them to complement your home's architecture and personal style. If you choose to paint or stain the lattice, make sure to cover all sides of the wood. Allow the paint or stain to dry completely before attaching the panels to your deck or porch.

Attaching Framed Lattice Panels:

Finally, you are ready to attach the framed lattice panels to your deck or porch. Use 3 or 4-inch straps, T-hinges, or T-plates to secure the panels in place. Screw the hinges or T-plates to the lattice frames first, and then attach them to the porch or deck using a drill with a screwdriver head. Ensure that the panels swing up and down smoothly and make any necessary adjustments by removing or adding soil in front of and underneath the panels.

By following these steps, you can successfully attach plastic lattice to frames and create a functional and aesthetically pleasing addition to your outdoor space.
