So, this might a bit of a curfball questions. This is one of the walls in our basement in our house in the Azores. Very humid and salty climate. There are a lot of cracks in between the natural stones that the walls are built from. Every week I'm sweeping up loads of debris from the plaster that's crumbling out. I'd like to cover up the gaps in between the stones with a grout that does not cause any new problems like growing mold, etc. What materials would you recommend I use for this?

Wildlife habitat: These areas provide critical habitat for salmon, trout, elk, and other species that depend on undammed, unlogged streams and connected landscapes.

Old growth & carbon storage: Roadless areas contain vast swaths of the nation's remaining old-growth forest and store significant amounts of carbon.

Wildfire risk: Wildfires are 4x more likely to start near roads, and roughly 90% start within half a mile of one — directly undercutting the administration's stated rationale for the rollback.

Drinking water: Roadless national forests provide drinking water to 60 million Americans, since intact forests filter water naturally.

Fiscal responsibility: The existing road network already carries an $8.5+ billion maintenance backlog, and building more roads would only add to it.

I've worked in fashion industry over 20 years. And this is one of the pineapple farms connected to the material we're working with now. The huge amount leaves can be processed to extract fiber.

I’ve been digging into this for work and the biggest headache so far is getting reliable emissions data in one place. It seems like different teams keep their numbers in spreadsheets, invoices, supplier records, etc., which makes it hard to build a complete picture.

How are other companies handling this once things get bigger, especially when Scope 3 and supplier emissions come into play? Are you still piecing everything together manually, or are you using dedicated software to keep the data and reporting under control?

I’m currently looking at Sweep as one option since it seems to bring emissions tracking, supplier data and reporting into the same workflow instead of having everything scattered across different files.

From Agricultural Resources to Sustainable Materials for the Global Textile Industry

Dhaka, Bangladesh — As the global textile and manufacturing industries search for renewable, biodegradable and lower-impact alternatives to conventional materials, a young Bangladeshi company is working to transform one of the country’s most abundant resources—agricultural biomass—into commercially valuable natural fibers.

Friends Fiber Yarn Limited (FFYL) is a Bangladesh-based natural-fiber manufacturing, sourcing and exporting company established in 2025. With its head office in Dhaka and production operations in Madhupur, Tangail, FFYL is developing a business around Pineapple Leaf Fiber (PALF), Banana Fiber, Cottonized PALF and Cottonized Banana Fiber, with applications extending from textiles and yarn development to composites, nonwovens, handicrafts, sustainable fashion and other bio-based materials.

The company’s story begins with a simple proposition: what is considered agricultural waste can become a valuable industrial resource.

A New Chapter for Natural Fibers in Bangladesh

Banana plants and pineapple cultivation generate significant quantities of plant residues. After harvesting, banana pseudostems and pineapple leaves are frequently treated as agricultural by-products with limited economic value.

FFYL sees an opportunity in these materials.

Instead of viewing discarded plant biomass simply as waste, the company works to recover the natural fibers contained within it and prepare them for higher-value applications.

Its website describes the FFYL approach as a circular-economy model: collecting agricultural resources, extracting natural fibers, cleaning and drying them, grading them according to characteristics such as fineness and strength, and preparing them for commercial use.

This approach connects agriculture with manufacturing while creating a pathway for natural materials to enter modern supply chains.

From Banana Stems to Premium Natural Fiber

Banana Fiber is one of FFYL’s principal product categories.

Extracted from banana pseudostems, banana fiber can offer a distinctive combination of natural strength, breathability, texture and biodegradability. Depending on grade and processing, it can be explored for textile applications, handicrafts, composite materials, nonwoven products, packaging and other sustainable-material applications.

FFYL supplies different grades of banana fiber for different end uses, including textile-oriented material and stronger grades for craft and industrial applications.

The company is also developing Cottonized Banana Fiber, aiming to make banana-based fiber more suitable for blending and yarn-development projects.

For the textile industry, this is an important direction.

The future of natural fibers will not depend only on discovering new plants. It will also depend on making those fibers compatible with existing industrial systems.

Pineapple Leaves Become a New Textile Resource

Another major focus of FFYL is Pineapple Leaf Fiber (PALF).

Pineapple leaves are a natural agricultural resource that can contain strong, fine fibers. FFYL processes pineapple leaves into fiber intended for textile, fashion, craft, composite and other sustainable-material applications.

The company’s PALF portfolio includes premium natural pineapple leaf fiber as well as Cottonized PALF, a spin-oriented form developed to facilitate experimentation with blended yarns.

This reflects FFYL’s broader ambition: to move natural fibers beyond traditional handicrafts and into modern industrial textile development.

The company is positioning Cottonized PALF as a potential material for blending with conventional and regenerated fibers such as cotton, viscose, modal and other suitable textile fibers, subject to spinning-mill testing and product requirements.

From Raw Fiber to Spin-Ready Innovation

One of FFYL’s most important areas of development is the transition from raw natural fiber to industrial-ready fiber formats.

Raw agricultural fibers often require additional preparation before they can be evaluated by modern spinning mills. Fiber length, fineness, cleanliness, moisture, softness, strength and staple formation can all influence their suitability for yarn development.

FFYL’s Cottonized PALF initiative is therefore aimed at addressing an important gap between agricultural fiber extraction and the requirements of textile manufacturing.

The company is seeking collaboration with spinning mills, yarn manufacturers, textile producers, sustainable-fashion companies, material developers and research organizations interested in developing new natural-fiber blends.

Its public communications also show a growing emphasis on research and development, encouraging universities, textile institutes and material researchers to evaluate banana fiber and PALF in areas including yarn development, composites, sustainable fashion, nonwovens and new-material innovation.

Building a Circular Fiber Economy

For FFYL, sustainability is not intended to be limited to the final product.

The company’s business model is connected to the idea of a circular agricultural economy—where plant residues can be recovered, processed and converted into new commercial materials.

Such a model can potentially create value at several levels.

Farmers can gain additional economic opportunities from agricultural by-products. Local processing can create employment and technical skills. Manufacturers receive access to renewable fiber resources. And global buyers gain another option for developing products with plant-based materials.

FFYL’s website states that its supply-chain vision includes relationships with rural farming communities and opportunities for local employment and artisan participation.

In this sense, the company sees natural-fiber development not only as a manufacturing opportunity but also as a way of connecting Bangladesh’s rural agricultural economy with international sustainable-material markets.

Bangladesh as a Source of Sustainable Materials

Bangladesh is globally recognized for its textile and garment manufacturing capabilities. The country possesses a large textile manufacturing ecosystem, experienced workers, established export infrastructure and a long history of supplying international markets.

FFYL believes Bangladesh can also play a stronger role further upstream—as a source of innovative natural fibers and sustainable raw materials.

Rather than limiting Bangladesh’s role to garment manufacturing, the company wants to contribute to the development of new material supply chains originating from the country.

Its vision is to connect Bangladesh’s agricultural resources with international textile manufacturers, spinning mills, brands, researchers and material innovators.

This creates an interesting intersection between two of Bangladesh’s important economic strengths: agriculture and textiles.

A Young Company with a Global Ambition

Although Friends Fiber Yarn Limited was established only in 2025, its business direction is deliberately international.

Public supplier profiles identify FFYL as a manufacturer/exporter and show its focus on Banana Fiber and Pineapple Leaf Fiber, with commercial interest extending into international markets.

The company is developing relationships with prospective buyers and industrial users across different markets while offering samples, technical specifications and customized fiber solutions for product-development projects.

Its public business communications show particular interest in international textile markets, spinning mills, sustainable fashion, research institutions and manufacturers exploring bio-based materials.

For a young company, the objective is therefore larger than simply selling fiber by the kilogram.

The long-term ambition is to become a reliable Bangladesh-based source of innovative natural-fiber materials for global industry.

Beyond Textiles

Although textile and yarn manufacturing remain central to FFYL’s strategy, the potential applications of its materials extend considerably further.

Banana Fiber and PALF can be explored in areas such as:

• Sustainable textiles and yarns
• Natural-fiber blends
• Sustainable fashion
• Nonwoven materials
• Handicrafts and lifestyle products
• Vegan-material development
• Composite materials
• Bio-based boards and panels
• Sustainable packaging
• Handmade paper and related products
• Research and academic development
• New-material and product innovation

The company is particularly interested in collaboration with researchers and manufacturers who want to test natural fibers in applications beyond traditional textiles.

This multidisciplinary approach could become an important part of FFYL’s future.

Quality, Customization and Export Readiness

Entering international fiber markets requires more than having a sustainable raw material.

Consistency, grading, moisture management, packaging, fiber specifications and communication with buyers are essential.

FFYL states that it prepares fibers according to quality requirements and offers customized specifications where required. Its website identifies quality-control considerations including moisture management, fine combing, tensile testing and secure export packaging.

This export-oriented approach is intended to help international buyers evaluate Bangladeshi natural fibers not simply as craft materials, but as potential industrial raw materials.

The Vision Ahead

The global materials industry is entering a period of significant change.

Consumers are demanding greater transparency. Fashion companies are exploring renewable and recycled inputs. Manufacturers are looking for alternatives to fossil-based materials. Researchers are developing bio-based composites and new-generation textiles.

Within this changing environment, natural fibers derived from agricultural resources may have an increasingly important role to play.

Friends Fiber Yarn Limited wants to be part of that transformation.

Its vision is straightforward but ambitious:

to turn Bangladesh’s agricultural resources into globally relevant sustainable materials.

The journey from a pineapple leaf or banana pseudostem to a commercial textile fiber may appear simple, but it represents a much larger opportunity—connecting farmers, processors, researchers, textile manufacturers, designers and international buyers through a circular value chain.

For FFYL, the objective is not merely to sell Banana Fiber or Pineapple Leaf Fiber.

It is to help create a future in which agricultural resources are valued as raw materials, natural fibers become part of modern manufacturing, and Bangladesh becomes recognized not only as a textile manufacturing hub, but also as a source of innovative sustainable materials.

From Bangladesh to the World

Friends Fiber Yarn Limited represents a new generation of Bangladeshi enterprise—one that sees sustainability, agriculture, technology, manufacturing and international trade as interconnected opportunities.

From banana stems to fiber, from pineapple leaves to PALF, and from natural resources to new industrial possibilities, FFYL is building its story around one central belief:

Nature already provides many of the materials the future needs. The challenge is to unlock their value responsibly.

I’m researching renewable energy technologies for a large navigable freshwater river and would appreciate some engineering input. The river reach I’m looking at has an average discharge of ~8,076 m³/s, an estimated river-current power resource of ~290 MW, and an average annual energy resource of about 2,540 GWh/year before recovery factors. The flow is relatively consistent, and I’m trying to determine what type of in-stream energy technology would be the best fit. I’m considering horizontal- or vertical-axis hydrokinetic turbines, ducted turbines, oscillating hydrofoils, biomimetic membranes, or other emerging technologies.

For a river with this level of flow, along with commercial navigation, debris, sediment, and environmental considerations, what technology would you recommend and why?
